Double storey extensions

If you need to add more than one room to your home, a double-storey extension is a cost-effective option as you will be using one roof and the same foundations for both levels.

You could create a large kitchen with dining area and easy access to the garden on the lower half, and an additional bedroom, large family bathroom, office or even a home gym on the second half.

Two storey home extensions can be built onto the back or the side of the house. A rear double-storey extension can have either a flat or a pitched roof, while an extension added onto the side of the house will generally need to have a pitched roof similar to the existing one with the roofline being preferably slightly lower.
