Loft Conversion – Camden, North London
This Camden flat has been completely reimagined with a loft conversion refurbishment, adding an entire new floor and transforming the home into a light-filled, spacious living area. The owners wanted to maximise space and natural light, making the most of their prime North London location.
To ensure the structure was safe, stable, and fully compliant with Building Control, PorthouseDean provided expert structural calculations, supporting the design and construction of the new loft level.
Maximising Space with Smart Structural Design
This project featured:
✅ A full additional floor – Creating a new living space in the existing footprint
✅ Structural reinforcement for the loft level – Ensuring long-term safety and durability
✅ Large glazing & skylights – Maximising daylight in the top-floor space
✅ Steel beam (RSJ) design – Supporting open-plan areas and large structural openings
What we did
Our structural expertise included:
✔ Structural calculations for the loft conversion – Ensuring compliance with Building Control
✔ RSJ & steel beam design – Supporting wide-span openings and maintaining stability
✔ Load-bearing wall assessments – Ensuring safe structural modifications
✔ Foundation analysis – Evaluating load distribution for the additional floor
Thanks to precise engineering, the loft conversion has turned this Camden flat into a bright, modern home, with an elevated city view and a more spacious, functional layout.

Why Extend Your Home?
More Space, More Possibilities
Create an open-plan kitchen, a family hub, or a bright entertaining space.
A Date You Can Plan Around
You choose the delivery date, and the price follows the date.
More Natural Light
A wider opening to the garden needs a beam sized for the load above it. The calculations set that size.
Personalised Design
Every house is built differently. The calculations work from your drawings and the structure you already have.
