Product Overview

Structural columns

Depending on the look you choose, your columns can be wide or narrow, full height or sit on a low wall. They could also be situated at the rear corners too, against the wall of your home and in between frames on each side of door openings. The choice is yours.

Building Regulations

Our extensions including columns and different roofing types have been designed and pre-approved to meet building regulations. This means that you do not have to worry about any compliances and waiting around for a building inspector.

Weather efficiency

Its advanced roof and glazing units possess excellent U-values, making it warmer and cosier in the winter and cooler in the summer. The extension offers safe, durable structure that has been tried and tested to cope with the UK climate.

Easy Install

Every piece and component used as part of your project has been assembled as far as possible ready to be delivered at your chosen location for you to install as easy as possible. This also means that we know that the extension you’re building is of the highest quality possible.
