What Informed Homeowners Do Differently
The varied housing stock — from Victorian terraces in the NN1 area to the large post-war estates on the town's expanding edges — offers a range of extension possibilities depending on the specific property and plot, and the town's ongoing growth has sustained a strong local construction industry familiar with all scales of domestic extension work.
The area is a town in Northamptonshire, East Midlands, administered by West Northamptonshire Council. The postcode districts covering the area are NN1–NN6. Nearby areas include Wellingborough, Daventry, Kettering, Towcester.
