Home Extensions in Oldbrook Milton Keynes

Oldbrook sits within Campbell Park parish and borders some of the most central parts of Milton Keynes. The area was developed in the late 1970s and early 1980s and features a mix of terraced houses semi-detached homes and some larger detached properties.

The terraced and semi-detached homes that make up much of Oldbrook are well suited to single storey rear extensions that transform the ground floor layout. Opening the kitchen into a larger open-plan living and dining space is the most common brief we receive in this area — and the consistent plot sizes mean we can plan and price accurately from the first site visit.

Some properties in Oldbrook have also benefited from above-garage extensions — adding floor area at first floor level without touching the garden. This is a more complex structural project but one we have delivered here successfully and it can add significant space on plots where a traditional rear extension would be limited.

We have completed three extension projects in Oldbrook including a single storey rear extension a building extension above the garage combined with a rear extension and a further residential extension.
