Garden Rooms for Listed Buildings

If you're looking for architects for listed buildings, we'd be happy to assist.


KAS have successfully obtained planning approval for garden rooms within listed buildings. You cannot exercise Permitted Development rights with listed buildings. Therefore any design needs to demonstrate compliance with planning law and local planning guidance.

Listed buildings are protected by law due to their cultural, historical, or architectural importance. This status means any alterations or additions must go through rigorous scrutiny to ensure they do not compromise the building's integrity. Garden rooms present an attractive option for homeowners seeking to expand their living space without jeopardising the authenticity of their listed property.

One of the key considerations when adding garden rooms to listed buildings is sympathetic design. These structures must complement the existing architecture while introducing modern elements. As architects we may consider design measures such as matching materials, mimicking architectural features. Another important aspect to consider is the size of the garden room. This is a contentious

What can I use the garden room for?


Garden rooms can provide a range of benefits for listed buildings. Firstly, they offer additional living space without altering the original structure. This is particularly advantageous for properties with limited indoor space or restrictions on alterations. Garden rooms can serve various purposes, from home offices and gyms to relaxation areas and entertainment spaces, enhancing the functionality and versatility of your property. The below highlights the potential uses for a garden room. It is also possible to combine multiple uses into one garden room such as our Belsize Park Garden Room.

1. Office
As the culture of working from home has become the norm for many people, the need for a dedicated office space within our homes has become important. A garden office can be a place to escape the house and provide a quiet, dedicated working environment.

2. Gym
A garden room can serve as a dedicated gym, pilates or yoga space, providing a tranquil and private environment.

3. Music Studio
The need for a dedicated music studio or music practice room can be a good use for a garden room with appropriate sound proofing.

How much will it cost to build a garden room?


The cost of building a garden room can vary depending on size, the type of foundations, internal and external materiality. Professional fees will also need to be taken into account. You will need to appoint an architect and engineer, but there may also need to be specialist appointments such as an arboriculturalist if there are any large trees close to the garden room. Most boroughs in London now require all outbuildings to have a green roof too, as any garden space lost to the outbuilding needs to be substituted and mitigated to not have any negative impact on biodiversity.
