About internal windows and borrowed light

An internal window is a fixed glazed panel set into an internal wall to borrow daylight from a bright room for a dark one — an inner hallway, a landing, a windowless bathroom or a box room. A glazed fanlight over a door does the same job. Full details on internal windows and borrowed light.

Internal windows and borrowed light for Northamptonshire properties

Across Northamptonshire we work in a real mix of properties — Victorian terraces in Northampton, ironstone cottages and newer estates around Corby and Wellingborough. Each brings its own details: uneven floors in older houses, deep skirtings, solid or stud walls and ceilings that aren't quite square. We measure for all of it. On the commercial side, much of our Northamptonshire work involves offices and logistics sites along the M1 and A14.
