Garden House Extension – Bury, Greater Manchester
This Bury home has been transformed with a modern garden house extension, creating a bright, spacious, and highly functional living space. Designed to seamlessly connect indoor and outdoor living, this extension provides extra room for relaxation, entertaining, or a home office, all while ensuring structural stability and compliance with Building Regulations.
To ensure the extension was built for long-term durability, safety, and efficiency, PorthouseDean provided expert structural calculations, supporting the steel beam reinforcements, foundation design, and load-bearing wall modifications.

Why Extend Your Home?
More Space, More Possibilities
Create an open-plan kitchen, a family hub, or a bright entertaining space.
A Date You Can Plan Around
You choose the delivery date, and the price follows the date.
More Natural Light
A wider opening to the garden needs a beam sized for the load above it. The calculations set that size.

Every house is built differently. The calculations work from your drawings and the structure you already have.
