Extension (Ewell, Surrey)

Maximising Space & Light with a Rear Extension in Ewell, Surrey

With a growing need for more space, better flow, and modern living, this homeowner wanted to extend and transform their home into something more functional and stylish. Their existing layout felt disjointed, with separate rooms limiting how they could use the space.

A single-storey rear extension was the perfect solution to open things up, improving connectivity between the kitchen, dining, and living areas while flooding the home with natural light.

Creating an Open & Airy Ground Floor

While the property had great potential, it lacked a cohesive, modern layout. To fix this, the design introduced:
✅ A full-width rear extension to integrate kitchen, dining, and living areas
✅ Steel beam supports to allow for wide, open-plan spaces
✅ Large glazing panels and skylights to maximise light and garden views
✅ A seamless transition between old and new, blending period character with modern design

The result? A bright, open space that’s perfect for entertaining, relaxing, and everyday family life.

Structural Engineering for a Seamless Build

To bring this vision to life, PorthouseDean provided:
✔ Structural calculations for RSJs & steel beams – ensuring the open-plan layout was fully supported
✔ Load-bearing wall assessments – safely reconfiguring internal spaces
✔ Foundation design for the new extension – ensuring long-term stability
✔ Building Control compliance – a hassle-free approval process

By working alongside Fluent Architectural Design Services, we ensured the engineering met all design goals without compromising structural integrity.
