Single storey extension on back garden on SIP - with planning permission


We hired Sunny to work on an extension to our semi-detached mid-eighties brick house in Blackheath, South East London. The project was designed to be a simple monolithic black box with a bespoke BBQ and decking area. We wanted the project to be sustainable, low carbon footprint and finished within 8 weeks. Not an easy task for a builder. After interviews with many different builders, we trusted Sunny with the task of carrying out the works

The project was conceived in-house using a non-traditional construction method inspired by jigsaw puzzles. All insulated panels and timber pieces were pre-cut during the manufacturing process allowing for a simple and fast assembly resulting in a timely finish. The use of SIP was motivated by high-energy efficiency, reduced wall thickness and structural integrity and the result did not disappoint.

Sunny went the extra mile by delivering on time, displaying true craftsmanship and improving details and proposed solutions.
