For detailed information about site access and installation, please visit our FAQs.

Planning Permission

In many cases, our smaller garden rooms and home office builds fall within permitted development, taking into account their square footage, height and the nature of their use. Our larger builds however may require prior permission, we recommend checking with your local planning officer.  

We can supply technical and 3D visualisation drawings, as well as measurement plans for your chosen build to aid any planning applications and architect meetings. We cannot advise on individual applications but are happy to help with the process.

Cladding

Our builds are made from wood, inside and out, floor to ceiling, so it’s a big part of what we do. We choose to use reclaimed timber for the external and internal cladding, floors and ceilings, with certified graded wood for the internal structure.

Reclaimed timber is what we’re all about, giving old materials a new lease of life; reusing and repurposing using traditional machinery.

Choose from a natural finish or stained black.

FAQs

The Boon Box garden room without its decking and porch is designed to fall within permitted development rights, taking into account its square footage, height and the nature of its use.

Yes, we can supply technical drawings and measurement plans for your chosen build, to aid any planning applications and architect meetings. We cannot advise on individual applications but are happy to aid the process.

Yes, we will need the area on which your prefab build will be placed, to be clear of any obstacles (i.e. rocks, trees, shrubs, sheds etc.). 

The same as with a standard garden shed from your local garden centre, any structure needs to be placed on a solid surface to ensure its stability. Whilst our builds come with levelling feet in each corner, the feet will need to land on a solid surface such as crushed hardcore or solid concrete. We recommend putting down a membrane beneath to stop any plants from growing up underneath your build.

We can install our builds on either a flat or gently sloping site area. If your site area slopes a lot then it may need levelling before we can install. As part of the ordering process, we will request photographs of the site area and access point, to assess its suitability and advise on how best to prepare your site ahead of your installation date. If you have any concerns about the viability of your site, please get in touch and we will be happy to help.

Our larger builds are constructed in our workshop and transported to site in either modular sections or as a whole, therefore we require a site access point of the minimum build width. Alternatively, the structure can be craned over fences and other buildings if viable.

As part of the ordering process, we will request photographs of the site area and access point, to assess its suitability. If you have any concerns about the viability of your site, please get in touch and we will be happy to help.

Our builds are constructed in our workshop and transported in modular sections for installation. In order to manoeuvre the building into place, we ideally need at least 0.5m from any obstacle around the entire structure. This would include locating the garden 0.5m from other buildings, fences, garages or trees etc.

Once ordered, our smaller builds like the Boon Box and Studio Room, will take up to 8 weeks to arrive, and 12 weeks for our larger builds. Any fully-bespoke builds will be estimated separately.
