Cost is a major consideration when developing your house. Looking for the cheapest route to have an extra room? Then changing your attic this way is likely your top pick.
The final price depends on various things, such as:
- Window size/number
- Roof size
- Usage
- Spec
Just need light and ventilation? It’ll be less expensive. Fancy smart fittings that automatically open/shut? You’ll pay a bit more. Live somewhere noisy? Insulation will help — at a higher price tag. You can also have a cabrio system to create a balcony.
