Forth Valley
Roof lanterns and rooflights for rear extensions in Forth Valley
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. We design and build rear extensions across Forth Valley, from Stirling and Falkirk to Alloa, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Rear extensions in Forth Valley gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Post-war semis and terraces are common around Forth Valley, and many have room for a single-storey rear extension within Class 1A limits.
