Sunroom extension to an existing stone dwelling to create an alternative type of living space.

Roots were invited to design a new sunroom extension which created an alternative living space to those in the original cottage. Roots chose to acknowledge the existing lean-to porch, which the Client had proudly built himself, by referencing its form and use of materials. The extension therefore takes on the form of a traditional lean-to, but is made from a series of sliding wall and roof planes. 

This creates an internal space which can be completely enclosed or completely open to suit the weather, with views to three points of the compass. The roof is standing seam zinc while the walls and sliding shutters are clad in Scottish larch.

Upon completion the Client has added a ground-mounted PV array and has proposals for timber decking.  In this way, the sunroom extension quietly becomes subsumed in the latest chapter of an evolving rural building cluster.
