Extension (Islington, London)

Project Overview

Rear Extension – Islington, London

This London home has been beautifully enhanced with a rear extension, creating a modern, open-plan living space designed for functionality and style. The highlight of the new space is a minimalist hidden kitchen extension, complete with a spacious kitchen island that adds extra workspace, smart storage, and a sleek, contemporary feel.

To bring this design to life, PorthouseDean provided expert structural calculations, ensuring that the large-span openings, open-plan layout, and structural modifications were fully supported and Building Control compliant.

Maximising Space with Smart Structural Engineering

This project was designed to:
✅ Extend the kitchen and living area – Creating a seamless, open-plan layout
✅ Introduce a large kitchen island – Adding functionality and improving workflow
✅ Enhance natural light – Using glazing and minimal framing for a bright, airy feel
✅ Ensure a strong structural foundation – Supporting the open-plan design with RSJs & steel beams

What we did

Our contributions included:
✔ Structural calculations for the rear extension – Ensuring stability and compliance
✔ RSJ & steel beam design – Supporting large openings for an open-plan effect
✔ Load-bearing wall assessments – Ensuring safe removal and modification of internal walls
✔ Foundation analysis – Reinforcing the base for the extended footprint

With expert structural engineering in place, this London home now features a light-filled, highly functional space, offering the perfect balance of practicality and modern design.
