Extension & Loft Conversion – Richmond, London
This Richmond home has been transformed and expanded with a rear extension and loft conversion, creating more space, better functionality, and a seamless blend of modern and traditional design. The homeowners wanted to enhance their ground floor layout for open-plan living, while the new loft conversion added valuable extra space upstairs.
To make this possible, PorthouseDean provided expert structural calculations, ensuring that every element was safe, compliant, and structurally sound. Working alongside Fluent Architectural Design Services, we helped turn this vision into reality.
Maximising Space with Smart Structural Design
This project focused on:
✅ A rear extension – Expanding the living space and improving the ground floor layout
✅ A new loft conversion – Adding additional bedrooms and increasing property value
✅ Steel beam (RSJ) design – Supporting large structural openings for an open-plan layout
✅ Enhanced natural light – Large glazing and skylights brightening the space
Engineering for a Strong & Efficient Build
Our structural contributions included:
✔ Structural calculations for the extension & loft conversion – Ensuring stability and compliance
✔ RSJ & steel beam design – Supporting large openings for a seamless open-plan feel
✔ Load-bearing wall assessments – Ensuring safe modifications to the existing structure
✔ Foundation analysis – Strengthening the base for the additional weight of the loft conversion
With our expert calculations, this home has been completely modernised, offering a spacious, stylish, and highly functional living environment.
