Paul Cashin Architects Project in Winchester Nears Completion

Building work for one of our side extension projects is scheduled to finish later this month.  The project, a modest contemporary side extension to a modern town house in Winchester, features an expansion of the kitchen and the creation of a snug.  Above the new spaces we have inserted a roof light looking up towards the brickwork of the house, whilst bringing southern light into the new rooms.

The scheme received planning consent during the winter of 2015 and started on site in July 2016.  The design features clean rendered walls and a slim line slate coping, with bespoke doors and roof light.  The interior is finished with bespoke timber joinery.
