WHY CHOOSE US?

We pride ourselves in using innovative building approaches to provide our customers with extenions, garden rooms and porches which are superbly insulated and can be used all year round. Energy efficient (built using SIP panels - from 100 to 250mm thickness), high security doors and windows, compliment the roof, floors and walls which have up to 228mm of class leading PU insulation. The thermal performance of PU (SIP) panels exceeds any EPS (Polystyrene) panel both in structural performance and insulation. This means that U-Values are as low as 0.10 ~W/m2 (which passes the passive house criteria), which will make your new building nice and warm in the winter and cool in the summer. As a result, you can expect low running costs and a great comfortable space to work or play.
