YOUR EXTENSION, BUILT IN WEEKS 

Home extensions built with precision manufactured MMC systems watertight in days and completed in weeks.  
 
Less disruption to your life, better energy performance than a traditional build and a finished space that looks exactly as it was designed. 
WHEREVER YOU ARE - WE CAN HELP 

AT THE START OR READY TO BUILD 

We work with homeowners at every stage of from the first idea to approved drawings in hand. 

JUST STARTING OUT 

You know you want to extend but you're not sure what's possible, what it costs, or which system is right. 

YOU HAVE DRAWINGS 

You've already worked with an architect and you have drawings with or without planning permission. 
WHY BUILD YOUR EXTENSION WITH MMC 

FASTER - EVERY TIME 

A traditionally built extension means months of trades working around your home weather delays, sequential waiting and months jusy to get watertight.  
 
Modern Methods of Construction (MMC) can change all of that completely! 
 
But, building systems alone can guarantee improved outcomes. It's our expertise and services with one team co-ordinating design, manufacture and installation who are accountable for the result, not just the frame. 
 
 
 
 

"MMC is the method, Our delivery is the guarantee"
