Home Extensions in Oakgrove Milton Keynes

Oakgrove sits in the east of Milton Keynes between Monkston and Broughton and was developed primarily in the 2000s and 2010s. The area features a strong mix of modern detached and semi-detached family homes on well-planned plots — newer properties that are increasingly reaching the age where homeowners want more space without moving.

The detached homes that make up a large proportion of Oakgrove have good plot proportions and are well suited to single storey rear extensions that open up the ground floor living space. Most properties here fall comfortably within Permitted Development — no planning application and no waiting on a council decision. Where a more substantial project is needed a double storey extension adds bedroom and bathroom space at first floor level alongside the extended ground floor.

Modern properties in Oakgrove were built to tighter energy standards than older MK housing stock which means the junction between the existing structure and the new extension requires careful detailing to maintain thermal performance. We address this at design stage rather than on site — which is why our extensions in newer properties consistently pass Building Control without remedial work.
