The right window type for a loft conversion depends on your roof structure, the room's layout, and your budget — there isn't one universally "best" option.
Roof Windows (Velux-Style)
The most common choice for straightforward conversions — fitted directly into the roof slope, less structurally invasive than a dormer, and generally the most cost-effective way to meet light and ventilation requirements.
Dormer Windows
Built out from the roof slope, dormers add genuine floor space and headroom alongside light, at a higher cost and with more structural work involved.
Gable Windows
Where a property has a gable end wall, a vertical window here can be a strong option, often bringing in more light with less roof alteration than either roof windows or dormers.
What Actually Drives the Right Choice
- How much headroom your existing roof structure offers
- Whether you need extra floor space, not just light
- Your budget and appetite for structural work
- Any planning or conservation area restrictions on your property
How We Help You Decide
- Survey your specific roof. Structure, pitch and headroom all affect which options are genuinely viable.
- Understand what you want from the space. A home office has different needs to a bedroom or bathroom.
- Give an honest recommendation. Based on your property and budget, not the most expensive option available.
