What's Included


Our experienced Architects  will guide you through the process and deal with all the relevant applications. Some extensions are  Permitted development so no planning is required, however all extensions will require a Building Warrant.

Local Authority Applications

Where possible we use Ground Screws for foundations.  This is a more sustainable approach by omitting the requirement for concrete.

The walls, floor & roof are SIP panels. For more info on SIP visit: Sip Panels | Sipit

Foundations & Structure

The high quality Aluminium door options are sliding, swing or bi-fold.  The aluminium frames are thermally broken which omits the risk of cold bridging.  This makes your home warm and draft free.

There are a range of external finishes that you can choose to make your extension unique, from the range of metal cladding, composite cladding, and smooth renders to the more characteristic timber cladding.

Margaret Rose, Edinburgh

We love our dab den, which was bespoke for a very awkward space in our garden. It totally maximises the wasted area we previously had and has given us a beautiful home office/design studio which is used every day. It is light, bright and airy with glass frontage and skylights; we are even able to partition areas off inside for privacy with frosted glass bi-folding well spent.


The underfloor heating also means that it is an extremely comfortable environment, even with the cold east winds in an Edinburgh winter! I would have no hesitation in recommending Dab Den for anyone looking for creative ways to extend their living/working space. ​

Newton Mearns, Renfrew

Colin and I would like to express our thanks at the result of the build.


Every person involved in the process was professional, courteous and skilled which is evident in the finished product.


We are delighted with our Dabden and are looking forward to may years of enjoyment from it.


Thank you so much​. 

Strathdon, Aberdeenshire

We applaud Dab Den for their marvellous efforts on our behalf, especially Kerr, who in all weathers was 'on site' and 'hands on' and Kat who kept her 'finger on the pulse' of orders and accounts.


The result is a wonderful 'Sitooterie' which we very much enjoy all year round - glad we specified the heated floor and the size and space afforded is excellent.


Very much appreciate the storage space too - the Belfast sink in the cupboard is a real boon. Thank you both for being very accommodating and providing us with a very much admired new 'garden room'. ​
