Questions about rooflight loft conversions in Forfar
How much head height do I need?
Around 2.2 metres or more from the top of the ceiling joists to the ridge is a good starting point. Insulation and new floor joists reduce the height.
Is it cheaper than a dormer?
Yes, usually, because the roof shape stays the same. But you gain less full-height floor space.
Can I have a bathroom?
Yes, where there is enough head height at the shower or bath position.
