The extension to this traditional White House in Scarinish provides a cosy new living space that becomes flooded with warming afternoon and evening sun.

Like the owners of many traditional buildings on the island, our client expressed a desire for enhanced views of the island landscape and a warm space to sit with lots of natural daylight.

The sunroom extension is positioned adjacent to the living room space which is accessed through an existing patio door.  The extension serves to expand the activity space of the living room into the new sunroom and beyond to a sociable sun deck with glazed ballustrade.  

Rooflights in the ceiling of the extension enhance the bright and airy qualities of the new sunroom and a large floor to ceiling window provides views towards Ben Hynish and the landscape in between.  A feature window with a frameless corner helps to open up the interior space to the landscape.

The sunroom is constructed from concrete poured into a polystyrene formwork to give a robust and insulated building fabric.  Electric underfloor heating is used to supplement heat gained from direct sunlight and maintain an even warmth in the sunroom.  


I recently had a sunroom added to the back of my house. Roots took care of everything - all the paperwork, site visits - everything!

I was [and still am] delighted with the finished result: Roots provided a first-class service from start to finish and I would not hesitate to use them again.
