Rear Extension – Chiswick, West London
This Chiswick home has been beautifully enhanced with a rear extension, creating a spacious, light-filled, and highly functional living space. The homeowners wanted to extend their ground floor, opening up the layout to improve flow, natural light, and connectivity with the garden.
To ensure the extension was structurally sound, compliant with Building Control, and efficiently designed, PorthouseDean provided expert structural calculations, working alongside the project team to support steel beam installations, load-bearing wall modifications, and foundation reinforcements.
Maximising Space & Light with Smart Structural Design
This extension was designed to:
✅ Expand the kitchen and living area – Creating a seamless, open-plan space
✅ Introduce large glazing & bi-fold doors – Maximising natural light and garden views
✅ Ensure open-plan stability – Using RSJs and structural steel for wide-span openings
✅ Improve property value – Enhancing functionality and aesthetics for long-term benefits

Our team provided:
✔ Structural calculations for the rear extension – Ensuring stability and compliance
✔ RSJ & steel beam design – Supporting large-span openings for an open-plan feel
