Single and double-storey extensions and wrap-arounds, designed, project managed and built by one team. Steelwork, glazing and open-plan living that adds real space and value to your home across Borehamwood and North London.

Rear, side-return and double-storey extensions, designed around how you actually want to use the space.
Structural steel, foundations and load-bearing openings handled in-house and signed off to building control.
Bifold and sliding doors, roof lanterns and rooflights that flood the new space with light.
We work from your plans or arrange the design and drawings, then manage the whole build to handover.
Yes. We can build from your architect’s drawings or arrange the design, structural calculations and building control sign-off for you, so it is all managed under one roof.
Most single-storey extensions take eight to fourteen weeks on site depending on size, groundworks and glazing. We give you a clear programme before we start and keep you updated throughout.
Many extensions fall under permitted development, but it depends on the size and your property. We will tell you honestly at the first visit whether you need full planning or not.
