A Rear Extension:
Perfect for a Young Family

A Rear Extension Adds Multi-Use Open Plan Space and Indoor-Outdoor Living

The Brief

Our client wanted a simple, modern extension to replace their existing conservatory and add much needed space to their kitchen. The conservatory was rarely usable, being too cold in the winter and too warm in the summer and the space was wasted.

The design concept was to expand the existing kitchen into an open plan multi-use room that could be used by all of the family at the same and brought the outside in.

The Project

Unlike the existing conservatory, the extension was designed to be open between the existing building and new space, and as such it would comply with current building regulations for extensions.

Our 150mm insulated SIP wall system and our 175mm insulated SIP roof system exceed the U-Values required of ‘new thermal elements’ and as a fully load tested system, structural calculations were prepared, ensuring that the building complied to building regulations, even before it reached our manufacturing facility.

Upon sign-off of the design by our client, production was scheduled, the SIP panels went into our workshop for manufacture and the full home extension kit was delivered to site.

Our client’s main contractor onsite was able to complete installation of the superstructure in just two days, which is approximately three times quicker than a traditional method of construction.

The main contractor then finished the panels internally and externally on site, following our tried and tested standard details and guidance.

The Outcome

The extension forms an integral part of this young family’s home and our client and his family now have a home that meets their needs, in which they can enjoy the naturally light, multi-functional space that’s been created.

Really, really pleased with it

Really pleased with it all and enjoy sitting and taking in the view, glass of wine in hand of course! We did new decking immediately outside of it, in order to open the bi fold doors fully as an extension to the room.  All in all, really, really pleased with it.

Such excellent service!

My wife and I just wanted to thank Richard, yourself and the rest of the team for all the support, ad hoc technical tips and advice that we got whilst building our Garden Room. I know that I visited the showroom 2 or 3 times and Richard and the team, even though quite busy, showed us every courtesy and help. Such excellent service! I have finally completed the build of our 3 x 5m Garden Room, and we are very pleased with it.
