Do you need planning permission for a garden office?

Since the pandemic, we have seen a huge rise in the interest of garden room builds. This is primarily due to the fact that people were spending far more time at home than previously.

Post lockdown, a large proportion of people still work either fully remotely or hybrid work, therefore a garden room can be a quiet space away from any distractions in the main dwelling, which can be made suitable for home-working.

This Harrogate garden room below is a great example of what can be built without planning consent, subject to criteria. One of the key benefits of this type of construction is the speed. The home office below took 2 weeks from start to finish. Compared to a traditional build, this is much quicker.

What can garden rooms be used for?

The possibilities of the use of a garden room are plentiful. Depending on what you would like from the space, design considerations can be made to meet your needs. Office spaces, lounge areas, gyms, game rooms and drink bars, to name a few, are all feasible. A combination of different functionalities are also a popular choice, which allows for even more usage from your garden room. Visual examples of each garden room mentioned can be seen below.

The only condition when it comes to your garden room’s usage is that it must not be a self-contained accommodation. In this case, it will become a separate dwelling which will require a separate address, and will not be categorised as a garden room.

Do i need planning permission?

In most cases, garden rooms can be constructed under Permitted Development, which means that full Planning Permission is not required. There is, however, a criteria that your garden room must follow to adhere to Permitted Development eligibility:

  • Area: Your garden room may not be greater than 50% of the land within your curtilage - this is normally more than enough.

    Please note that once you exceed 30sqm, you will require Building Control sign off. Most residential garden rooms are much smaller than this, but if you wish for a multi-functional garden rooms or more than one garden room, then it may start coming close to the size limit.

  • Height: If your garden room is built less than two metres from your boundary, it can be a maximum of 2.5 metres from the highest ground next to the building. However, if you are able to build it more than two metres away from the boundary between yours and your neighbours land, the allowance is more generous:

    • Maximum eaves height - 2.5 metres

    • Max flat roof height - 3.0 metres

    • Max pitched roof height - 4.0 metres

    Location: There are some restrictions when it comes where your property is situated. These are as follows:

    • National parks and AONBs: Within 20m of the rear of the house, or less than 10 square metres

    • Conservation areas: Directly behind the house

    • Listed buildings: Planning permission is always required

    • This is not permitted development forwards of a property

Whether your garden room can be built under permitted development or not, it is recommended that a Lawful Development Certificate is obtained. This will protect you from any potential future enforcement action when/if you sell your property.

Making your property eco-friendly

Since global warming is becoming a more pressing issue, many of us are looking at how we can minimise our carbon footprint on a day-to-day basis. Most of us spend a large proportion of our time at home, so it makes sense to convert our daily home routine into a more environmentally-friendly one.

There are several alterations which can be made in our homes to save energy . As well as being kinder to the planet, you’ll be saving money in the long run by implementing these changes, especially considering the extreme rise in household bills in the recent months.

Renewable Energy

Solar Panels

Solar power is possibly the most popular forms of renewable energy. Solar photovoltaic panels can be installed onto your roof, which convert the sun’s energy into electricity - this is then used to power your home. During daylight hours, the power generated is stored in batteries, therefore electricity use isn’t limited to when the sun is shining.

In the winter, you will typically be using more energy to heat and illuminate your dwelling, but your solar panels will be generating less energy due to fewer daylight hours hours and higher chances of cloudy days. However, contrary to common opinion, solar panels can work just fine during winter and will still save you a significant amount of money. This is due to the fact that during the summer, you will be generating far more energy than you are using, which as mentioned, is stored in batteries. This stored energy can then be used in conjunction with the smaller amount of energy generated over winter, to power your home during these cold months.

In terms of aesthetic appeal, solar panels are often described as ‘eye sores’. However nowadays solar panels can be disguised to match more traditional and other modern materials, such as natural slate.

air source heat pumps

This renewable energy system uses energy from the air outside to provide heating and hot water for your home - it basically works in a similar fashion to a fridge, but in reverse. Heat pumps can function even in colder temperatures, capable of heating your home even in freezing winters as low as -15 degrees Celsius.

There are two types of air source heat pumps:

  1. Air-to-water - this feeds heat from the outside air into your wet central heating system. They’re most suitable for large radiators or water underfloor heating because the heat they produce is cooler than conventional gas boilers. Therefore they are most effective when a large surface area is available to release the heat.

  2. Air-to-air - this transfers heat from outside air into your home through fans. A warm air circulation system is required to distribute the heat through your house. Unlike air-to-water heat pumps, this type does not produce hot water, therefore a separate water heater will need to be installed. During the summer, air-to-air heat pumps can also function as air conditioning, cooling down your home.

This efficient, clean and environmentally-friendly method of heating your home is virtually silent when operating, and can save you up to £1,330-£1,410 per year compared to electric heaters or gas boilers.

Another incentive to jump on board with this method is that the UK Government are offering grants of £5,000 towards the installation costs! Heating homes with air source heat pumps looks to be the way forward.

wind energy

Many people believe that wind turbines are only used to produce energy on an industrial scale. However, it is possible to have them installed either close to your property as a free-standing pole, or be placed on to your house directly. Electricity is generated by the wind turning the blades, which in turn creates power.

Installing a wind turbine to help power your property is a great way to save on energy bills. For example, it is estimated that a 6kW pole-mounted turbine could save you more than £340 a year on electricity bills, as well as earning you roughly £235 yearly in Smart Export Guarantee (SEG) payments - learn more about this here: Smart Export Guarantee (SEG): earn money for exporting the renewable electricity you have generated - GOV.UK (www.gov.uk). The renewable energy generated from a domestic wind turbine could save around 2.1 tonnes of carbon dioxide a year - hugely reducing your personal carbon footprint.

However, the typical cost of a turbine as described above is between £23,000-£34,000, and this source of renewable energy won’t be cost-effective for every home. It is recommended that the area of installation regularly reaches a wind speed of us to 6 metres per second - which isn’t common in most areas of the UK. If present nearby, obstructions such as other buildings, trees, hills and roof-mounted turbines will reduce the amount of wind passing by your property, thereby reducing cost-efficiency of opting to use wind power as renewable energy. Generally, only properties in remote, windy settings with few surrounding obstructions find that the benefits of installing a residential wind turbine outweighs the costs.

Getting a Smart Meter

If you aren’t in the financial position to invest in renewable energy options for your property, simply obtaining a smart meter can help you reduce your carbon footprint, whilst saving a considerable amount of money on bills. Smart meters track your home energy usage, meaning you won’t need to take manual meter readings anymore, and you’ll receive accurate energy bills. They allow you to track exactly how much energy you are using, which appliances are using the most energy, and which are more energy efficient. Therefore, you will be encouraged to alter your habits according to these insights, decreasing any unnecessary energy usage which you may have been completely unaware of. Furthermore, energy providers often offer deals and discounts for homes with a smart metre - so it’s a win-win really!

Can I build a house in my garden?

Is it feasible?

If you have a large garden or outdoor space surrounding your home, it may have crossed your mind to build a new house on the site - and it certainly could be possible and profitable! However, initially you will need advice from a good architect, and they will typically carry out a ‘feasibility study’. They consider many factors, including if your property is on greenbelt land - which decreases likelihood of planning permission acceptance. Other considerations prior to applying for planning permission are discussed below.

Planning permission

Firstly, you need to think about planning permission. All planning decisions are based upon both national and local planning policy. Unfortunately, policy is generally set up to resist such development for new dwellings but there are, as always, exceptions to the rule. Residential annex for example are supported by the NPPF (and in some circumstances are even possible under Permitted Development). Similarly infill sites within a settlement boundary are more likely to be successful.

There are several factors to contemplate before applying for planning permission which will increase your chances of being successful:

  • Do you have enough space for a second dwelling? And if so, where would you like it to be positioned? Policy includes for certain levels of amenity. This includes separation distances between properties, and minimum garden sizes among other criteria.

  • The style of the property proposed will also impact the likelihood of approval. Within a conservation area, area of outstanding natural beauty, national park or such protected areas a contemporary home is more likely to face resistance. Nonetheless the local authority will consider each application on its own merits.

  • Trees and protected species are a possible cause for permission to be refused. If your plot is located within a conservation area, the removal of any trees will be tricky to be approved, therefore a well thought-out landscaping plan is necessary. If your plot is potentially a habitat for any protected species, such as newts or bats, an ecological survey will be required.

Benefits of building a house in your garden

There are many huge advantages of constructing another dwelling on your plot, including:

  • A significant increase in the value of your land and property. - even solely doing the feasibility study and obtaining planning permission will likely uplift the current value. You don’t even need to build the house as selling your plot of land with planning permission, whilst staying in your own house, is a possibility.

  • It could serve as a huge convenience to yourself and your family, if you need space for extra storage, or require more room for a growing family or an elderly relative.

  • The property in your garden could serve as second income if you rent it out - this is a fantastic investment opportunity.

What is class Q planning?

Class Q is a form of development which allows the conversion of agricultural buildings into residential use. This was introduced in 2014, with the aim to reduce pressure for housing in rural areas. Providing the existing building meets certain requirements, converting under Class Q can be a much easier process than a full planning application. Barn conversions are highly desirable and often sell very easily - if you have a redundant agricultural building which you think has the potential for residential use, read on to see if this exciting opportunity is a possibility!

Is my barn suitable?

Firstly, your barn should be located within a settlement, an open countryside or within the greenbelt - it can not however be situated within an AONB, SSSI, Conservation Area, National Park or World Heritage Site. Listed buildings are also excluded from Class Q rights. The history of your barn is also important. It must've been solely used for agricultural purposes since at least 20th March 2013, including arable (crops) and pastoral (livestock) functions, and had no change of use since then. Structurally, your barn must have the foundations to be converted and already be “capable of functioning as a dwelling”. If it requires “the construction of new structural elements” prior to commencing the conversion, Class Q will not be applicable. Unfortunately, what is meant by “new structural elements” is unclear, as the replacement of walls, windows, roofs etc. is permitted under Class Q. The planning authority will have their say as to whether the existing building is fit for conversion under this development scheme.

What is possible (and what isn’t)

The maximum number of dwellings which can be created per agricultural holding under Class Q is five - and this may be accomplished in a combination of ways. A couple of examples are: three large houses, covering a total area of up to 465sqm, with an additional two smaller homes, limited to 100sqm each OR five smaller properties measuring up to 100sqm each. As long as the total area doesn’t exceed 865sqm and there are no more than five units, other various combinations of dwelling numbers/sizes may be possible. Additionally, the existing volume of the building must be retained, including insulation which must be internal, rather than applied externally to the face of the building. If a garden is desired, it can not be larger than the footprint of the building. A final note considering what is and isn’t possible is approval - although full planning permission isn’t require, you must still apply or prior approval.

What now?

If you don’t think that your barn matches the criteria for a conversion under Class Q development, a conversion may still be possible via full planning - you can get in touch with us to discuss further through the following link: https://www.edgarchitecture.co.uk/contact

If you believe that Class Q is for you then you have a few different options in terms of logistics and costs:

  • Traditional Appointment - you pay the fees and costs up to planning permission. This includes Architects, Planning Consultants, Engineers, Surveyors, Visual Landscape Assessments, Ecologists, and other necessary parts.

  • Joint Venture Agreement - This option is much less costly. EDG would absorb the fees and reports mentioned above, meaning you won’t have any other financial outgoings other than legal fees. In exchange, we would take a percentage of the profits from the sale of the barn. This can be sold after planning permission is granted, or after the building works are complete.

  • Option Agreement - in simple terms; we agree to purchase the building, access and garden area, at any point within a fixed timescale for ampre-agreed sum. This is usually a higher value than it would be worth as an agricultural building without planning permission

Do I Need Planning Permission?

The requirement for planning permission on a building project is usually straightforward to discern. However, every project is unique, and as a chartered architect practice, this question would be ours to deal with on your behalf.

It is true that certain home improvement projects now forgo the need for planning permission. However, many come with limitations and stipulations which must be followed. It is therefore always better to have professional advice from the beginning of a project. This will help prevent the need for remedial action, or indeed the prospect of prosecution.

It is worth remembering that architects can help you to see alternative approaches and look objectively at building and design development. At EDG Architecture, we can take care of planning permissions, obtain details on building regulations and source the necessary documentation. So, whether you would like a loft conversion, extension, new kitchen or the reworking of internal space, we can help you to make it a reality.

What is Permitted Development?

Permitted Development is any project where planning permission is not required. For example, when internal walls need repositioning or taking down or where replacement ceilings and floors, doors and windows or heating and plumbing are required. Ultimately, any proposed changes to the inside of the property are usually classed as ‘permitted development’.

The rights afforded to homeowners are extended to house extensions also. This includes both single storey, and double storey extensions to both the rear, and side of a property. There are conditions to these rights that include the scale, eave and ridge height, roof form, and the use of appropriate materials.

Where new windows are to be fitted, such a project would be a permitted development providing that it is in keeping with the original build. However, the addition of a bay window may require planning permission as it involves an alteration to the external appearance and may be classed as an extension.

The installation of a dormer window, or indeed a rooflight, would be permissible in some circumstances providing that restrictions are not in place for the property.

The introduction of solar panels is also considered permitted development with government backing. That being said, there are guidelines to follow as to the size and positioning of the panels. Therefore, professional guidance is recommended.

All works need validation at the end of a project. So, any shortcuts taken could result in problems in the long term. Should you come to sell your property, official evidence of ‘ticking the boxes’ is critical, as such evidence needs to be produced for the consideration of prospective owners. Ultimately, the overall safety of a build or development is the essential consideration of any structural change.

Article 4 Direction

Article 4 Directions are, in simple terms, restrictions to remove the Permitted Development rights afforded in normal circumstances. Some Local Authorities may issue an ‘Article 4 Direction’ to prevent house extensions, replacement windows, or to implement smoke control areas if, for example, it would spoil its appearance in relation to the neighbouring properties. Article 4 Directions form restrictions on developments and additional buildings in certain places.

Works that Often Require Planning Permission

All works outside of the limitations of permitted development require planning permission.

Common examples are:

•     External demolition work

•     Change of external appearance of a property

•     Extensions

•     Changes to flats or maisonettes

•     External walls and fences

Conservation Areas and Listed Buildings

For properties which are in conservation areas or are ‘Listed’ (meaning the buildings have a structure that is of a special architectural or historic interest), planning permission needs careful thought and application. An architect’s knowledge and expertise in such cases is invaluable. These primarily occur in places such as:

•   National Parks

•   Areas of Outstanding Natural Beauty

•   World Heritage Sites

•   The Norfolk and Suffolk Broads

What Does an Architect Do?

To those not involved in construction or development, the work of an architect is a little enigmatic. Whereas the roles of builders and electricians are clearly evident, an architect’s working life is less obvious.

Put simply, an architect helps building owners or developers to realise the building or adaptation of a property, with due regard to its style and purpose. A good architect will carry their work with efficiency and honesty.

However, there are several different aspects to the role of an architect – all of which we cover in this simple guide.

Concept Design

Here, the outline for the design is drawn up, with due regard to the brief. The initial design brings the brief to life, before becoming more detailed (this should incorporate both functional and practical considerations). In this initial stage, architects must also consider the wider impacts of the project, such as implications for the surrounding built and natural environment.


Developed Design

The development of the design follows. Here architectural, structural and practical considerations for the design build come under investigation. RIBA (the Royal Institute of British Architects) have recently called this process ‘spatial coordination’. Approximate costs, size, shape, location, tolerances and other such capacity and control systems are considered here to enable specifications to be configured.

Planning Applications

Architects often apply for planning permission on behalf of their client from the local authority.  For the large element of this, they will submit plans and drawings, but this will also include the completion of forms for the application, and associated documents where required.

Permissions may carry planning conditions restricting the use of a site or ask for additional approvals for specific parts of the proposal.

If the application is refused it may be possible to appeal or adapt the plans.


Tender Drawings

Tender drawings show the technical side of a design and are prepared to obtain a price from Principal Contractors. They show the design workings at functional level as well as the design’s construction. Plans, cross-sections, elevations and even visualisations may be produced as well as schedules and specification documents.

This package of drawings will also contain information required for the Health and Safety file.  This is a requirement of the Construction, Design and Management Regulations (2015).  Under these regulations the Architect is often considered as the Principal Designer. This is one of the ‘duty holders’ who are responsible for ensuring the safe construction.  Other duty holders include ‘Designers’, ‘Principal contractors’, ‘Contractors’ and  ‘Employers’.

SECTION 1.jpg

Building Regulations Application

Building regulations applications seek approval from the building control department of the local authority or from an approved inspector. In either case, a fee is payable (this will be in line with the proposal and the cost of the development). However, it is now possible on some relatively small concerns for tradesmen to self-certify their work, such as electricians and plumbers.

Generally, on large scale projects a ‘full plans’ application will be made. This means that the drawings and specification are approved prior to works commencing.  The Building Inspector will still make periodic visits to site.

On small projects such as an alteration to an existing property, a ‘building notice’ can be given. A building inspector then approves each stage of the project’s completion as it progresses.  This is usually more risk for the Client as you do not know if a specification will be approved until it is built. This can be costly for corrective works.

Construction Drawings

These are working drawings which provide information such as dimensions, materials, and construction details to be used by the contractors to bring to life the design. Construction drawings are also used by suppliers to make elements of the proposal or to assemble or install components, such as kitchens, stair cases etc.

Often during the construction process additional drawings become required to detail particularly tricky areas, or when specialist sub-contractor’s design elements become available.


Contract Preparations

Architects often prepare contracts to outline the intent, rights and responsibilities for the two parties involved. The contract’s legality will depend on its type and form. Whereas a ‘gentleman’s agreement’ is usually a verbal understanding (but can be written), a binding agreement takes the form of a legal contract and there are rights and obligations for both parties.

Each party will receive a copy of the ‘contract documents’.  This will include the contract itself, all drawings, specifications, and any nominated subcontractor information, as well as a copy of the tender sum, the programme of works and the Principal Contractor’s insurances.  This package will also include details from the structural engineer, as well as a pre-construction health and safety file to be continued by the Principal Contractor throughout the build.

RIBA contract suite.jpg

Contract Administration

02 Extension.jpg

Architects can act as the contract’s administrator. In this capacity, the architect acts on behalf of the client to ensure that any certifications, assessments or decision-making is carried out with the utmost integrity. Contract administration also includes the following responsibilities: preparing documentation for execution; preparing reports; agreeing testing and commissioning procedures; issuing certificates; making good defects and issuing the final certificate of completion.

As Contract Administrator our primary role is to play the part of the impartial adjudicator.  Should a disagreement arise it is our role to placate the situation and to advise who is liable or at fault in accordance with the contract document. The key to this is to ensure both parties are upfront about issues, and the financial implications of these so that these can be dealt with amicably.


Our Approach

We have experience across all stages of the design and construction phases and are well versed in finding solutions to unforeseen issues that may arise.  Often when ‘opening up’ the existing fabric it is discovered that defects were previously concealed.  In these scenarios we work to prioritise finding a cost-effective solution whilst maintaining relationships.

Why now is the right time to consider your next development despite Covid-19

The Covid-19 virus is expected to hit its peak in 14 weeks from now. After 30 weeks we should be almost back to business as usual.

Thanks to the government’s drastic measures most industries should survive the epidemic with a strong chance to pick up where they left off if they continue to act now. This is the same for the property and construction industry.
