Extension (Stockport, Greater Manchester)

Elevating Space with a First Floor Extension in Stockport, Greater Manchester

With growing family needs and a desire to make better use of their footprint, this homeowner in Stockport wanted to add extra living space without compromising the ground floor layout. Their solution? A smart, floating first-floor extension above an existing single-storey structure.

Unlocking New Space Without Expanding the Footprint

The extension created a generous new bedroom and bathroom, while maintaining full access and light flow to the garden below. The design focused on:
✅ Minimal impact on the ground floor — no internal reconfiguration needed
✅ Careful support detailing to accommodate the ‘floating’ effect
✅ Sympathetic design to tie into the original building aesthetics
✅ Improved thermal performance and future-proofed use of space

Structural Engineering Behind the Build

To make the floating structure work safely and efficiently, PorthouseDean provided:
✔ Steel frame design and connection detailing — to carry loads over the open ground floor below
✔ Foundation checks and bearing wall assessments — to verify capacity for the additional storey
✔ Roof tie-ins and wind load analysis — to ensure long-term stability in exposed locations
✔ Clear documentation for Building Control approval — smooth and stress-free compliance

Designed for Flexible Modern Living

This thoughtful extension now provides:
🏡 Additional living space without sacrificing garden or ground floor rooms
☀️ Large windows and elevated views across the surrounding area
📐 A future-proofed layout that can serve as a bedroom, home office, or guest suite
