Velux, dormer or L-shaped — find out what's possible in your Glasgow roof, what it costs, and what planning you need.
For families who love their street but have outgrown their square footage, a loft conversion is often the smartest move in Glasgow. You add a bedroom (or two) and an en-suite without losing any garden, and you avoid the planning friction of extending into the rear.
The cheapest and least disruptive option. The roof structure stays exactly as it is — you simply insulate, board out, add stairs and Velux windows. Best for properties with generous existing head height (many Glasgow Victorian terraces qualify).
A box dormer extends the roof outwards to gain head height and floor area. The most popular option for Glasgow 1930s semis and post-war stock where the original loft is too cramped.
For semi-detached and end-terrace properties with a sloping side roof — converts that hip into a vertical gable wall, adding significant floor area. Almost always combined with a rear dormer.
The biggest gain — replaces the entire roof slope with a near-vertical wall. Common on Glasgow tenement-style upper flats but requires full planning and significant investment.
Includes labour, materials and standard fit-out. Excludes architect's fees, planning fees and building warrant.
Velux conversions generally fall under PDR. Dormers, hip-to-gable changes and mansards almost always need full planning — and Glasgow City Council pays particular attention to dormers facing the public road. Whatever you build, you will need a building warrant: lofts must meet stringent fire-escape, insulation and structural requirements.
