Architects in Hertsmere
Hertsmere's towns, Borehamwood, Bushey, Potters Bar and Radlett, are surrounded by Green Belt, so the size of an extension relative to the original house matters as much as its design.

- FreeResubmissionIf planning is refused, we revise and resubmit at no extra design fee. Conditions
Most of our Hertsmere projects are extensions and loft conversions in Borehamwood, Bushey and Potters Bar. Outside the town boundaries the Green Belt applies, and extensions there must stay proportionate to the original house, so we check the original floor area and any earlier extensions first.
