Over-Structure Extensions

Add a Room Using Foundations Already in Place

An over-structure extension, sometimes called building above an existing structure, is one of the most cost-effective ways to add a first-floor room to your home. Because the footings and foundations are already in place, you can avoid the high cost of new groundworks while still gaining valuable additional space.

Common examples include adding a bedroom or bathroom above a single-storey rear extension, above a flat-roofed section of the house, or above an integral garage.

Hogs Back Builders has completed numerous over-structure projects across Surrey and Hampshire, and we can advise from the outset on feasibility and the structural requirements involved.
