Great Dunmow CM6
Extension builders serving Great Dunmow
Great Dunmow is a market town with period cottages in the centre and newer family estates around the edges.
From a wrap-around extension for the largest footprint to a double storey extension for extra bedrooms, every project starts with a free consultation and survey, followed by a fixed, itemised quote once the scope is agreed.
Planning applications in Great Dunmow are handled by Uttlesford District Council. Many home extensions fall under permitted development, but if your home is in a conservation area those rights can be more limited, so we check this at the survey stage and can manage any application for you.
Our base at Ford End, near Chelmsford, is around 4 miles from Great Dunmow, so you are close to home for us.
