Coffee Hall sits in the east of Milton Keynes — a residential neighbourhood developed in the 1970s as part of the original new city masterplan. The area is compact and well established with a mix of housing types that includes terraced properties maisonettes and small detached homes sitting on modest but workable plots.


Extensions in Coffee Hall require a more considered approach than some of the larger-plot areas across MK. The terraced and semi-detached properties that make up much of the estate have less rear depth than the detached homes you find in Westcroft or Wavendon Gate — but that does not mean extension is off the table. A well-designed single storey rear addition of even modest proportions can significantly improve how the ground floor functions, and that is consistently what homeowners here are looking for.

Side returns — the narrow unused passages that run alongside many terraced properties in Coffee Hall — are worth examining closely. Incorporating a side return into a rear extension widens the new space considerably and the result often surprises clients who assumed the footprint was too tight to do anything meaningful with.
