Updated: Jan 13, 2023

This is probably one of the common questions we get asked. How much extra space will I get by have a dormers, instead of converting within the roof space and putting in Velux Roof windows.


The answer will vary depending on what type of dormer you have, but some most dormers can have a substantial difference in overall useable space and head height.


When ever we offer a loft conversion the first question we ask if do you want a loft dormer. Why? Well the other than the obvious

After The Loft Conversion

Once the loft conversion was finished you can now see the difference in usable floor space and height height with the dormer fitted. On the left side, you can see beyond the alcove it is no longer walkable. On the right photograph, you can now see the room opens up creating a large walkable space and also hosting an ensuite with freestanding bath.
