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 Devon properties
We regularly work in Georgian terraces in Exeter, naval-era houses in Plymouth, thatched cottages and coastal homes around Devon. In older homes we scribe frames to walls that aren't plumb; in newer ones it's usually a case of finding the studs and services before we fix. Businesses here come to us as well, particularly offices on Exeter's business parks, in Plymouth city centre and around Torquay.
