When our client bought this traditional Tiree White house it quickly became apparent that the extension that wrapped around two sides of the building was poorly constructed and had to be replaced.

The existing sunroom, although damp and draughty, had offered valuable additional living space with views over Crossapol bay.  The existing extension to the rear also included kitchen and utility space that was particularly useful for the storage of watersports equipment.

Our brief was to revive the sunroom and extension so that it they tie in more effectively with the traditional white house, whilst taking opportunities to maximise views of the landscape and give the project a more contemporary style.

The new roofline was adjusted so that it would not interrupt existing windows; as the previous extension had.  The new proposal was constructed from concrete cast into a polystyrene formwork, this made for a more robust and well insulated structure.  The large window openings give the views from the interior a cinematic quality and become the focus of attention.  Recessed LED lighting accents the clean edges of the new sunroom. 

On the exterior western red cedar cladding is used to celebrate the contemporary qualities of the new sunroom and contrast with the white washed masonry of the traditional house.  The timber cladding has been left untreated so that in time it will weather to a silvery grey.  Untreated timber cladding is a low-maintenance material and will help the extension to blend in with the landscape.



We were introduced to Michael and Lynne by our builder in Tiree when it became apparent that we would need to demolish an old extension and start again.

We met with them initially and they listened to what we were looking for in our new build then transferred our thoughts to a series of drawings for us.

Throughout the process of planning we felt fully involved and in control of the aesthetic of the end result, despite the fact we were communicating often via email. Micheal and Lynne completed all the planning applications etc for us and all went smoothly with no hiccups.

We are delighted with the final result and with the way Micheal and Lynne liaised with the builder to complete the build.

We would have no hesitation in recommending the Roots team to anyone wanting to plan for building in the challenging environment of The Hebrides.
