Traditional Timber Frame Extensions for Your Home

We are proud to offer a wide variety of options for beautiful, bespoke, and traditionally-crafted timber frame extensions for your home in the UK. Whether you’re looking for a more comfortable living or entertainment space, a new and tranquil setting for your home office, or even if you need more room for a private gym or indoor swimming pool – we will be glad to build it to your exact needs and specifications.


Bespoke Timber Frame Extensions in the UK

Offering bespoke designs for freestanding wooden buildings and house extensions is all part of our award-winning service. This means that if you already have ideas in mind for your very own timber-framed structure and feel that it offers all the room you need for work, leisure, or storage, we are more than ready to help you make these plans a reality.

We can even manufacture large, complex designs for multiple uses, including combined offices and garages, hobby and entertainment spaces, and art studios or workshops.

With an experienced team of master craftsmen on hand, we’ll be here to expand your home and transform it into the space you’ve always imagined. Our work will even blend seamlessly with the rest of your property, adding charm and an aesthetically pleasing finish alongside the new interior space.

Planning Permission for Timber Home Extensions

There are several stipulations involved when you wish to build a timber frame extension for a house, while adhering to both planning permission and Building Regulations. These include stipulations around:


  • Ensuring that the materials used in exterior work have a similar appearance to the existing property (with the exception of conservatories)


  • Ensuring that no more than half the total area of the property (excluding the original house) is occupied by extensions or other buildings
  • Ensuring that no part of the extension extends beyond a wall facing a road, if it is a principal or side elevation
  • Ensuring that your extension is not wider than half the width of the house
  • Ensuring that side extensions are only one storey high and no more than 4m in height
  • Ensuring that extensions built within 2m of the property boundary have eaves that are no more than 3m in height
  • Ensuring no part of the extension is higher than the highest point of the roof of the original property
  • Ensuring the pitch of the extension’s roof matches the pitch of the existing roof as practically as possible
  • Ensuring single-storey extensions are built no closer than 3.5m to a boundary with a road to the rear
  • Ensuring multi-storey extensions are built within 7m of a boundary to the rear of the house


  • Ensuring the extension is kept to a single-storey structure when built on designated land (e.g. national parks, the Broads, conservation areas, World Heritage Sites, or Areas of Outstanding Natural Beauty (AONB’s))
  • Ensuring extensions on designated land do not extend beyond an adjoining principal or side elevation

The Type of Property

  • Ensuring a single-storey rear extension does not extend further than 4m from the wall when the property is detached
  • Ensuring a single-storey rear extension does not extend further than 3m from the wall when improving any other kind of property

The Type of Extension

  • Ensuring that any extension with multiple storeys does not extend further than 3m

There may be further stipulations besides these that apply in your local area, so we would always recommend that you contact your local authority before planning a timber frame construction.
