Cottage renovation (Bicester, Oxfordshire)

Project Overview

Cottage Renovation – Oxfordshire

This Oxfordshire cottage has been expertly renovated to blend traditional charm with modern open-plan living. The homeowners wanted to retain the character of their property while introducing a more spacious and functional ground floor layout. To achieve this, a 7.0m long-spanning steel frame was designed, allowing for a seamless, open-plan space without compromising structural integrity.

To ensure stability, strength, and compliance with Building Control, PorthouseDean provided precise structural calculations, supporting the installation of long-span steel beams and load-bearing reinforcements.

Preserving Character While Creating Space

This renovation was designed to:
✅ Create a 7.0m open-plan space – Removing restrictive walls for a modern layout
✅ Introduce a long-span steel frame – Providing essential structural support
✅ Maintain the cottage’s original charm – Blending contemporary living with period features
✅ Ensure long-term stability – Reinforcing the structure while enhancing space and light

What we did

Our role included:
✔ Structural calculations for the steel frame – Ensuring safety and compliance
✔ RSJ & long-span beam design – Supporting wide structural openings
✔ Load-bearing wall assessments – Allowing for safe wall removal while maintaining integrity
✔ Foundation & load distribution analysis – Strengthening the base for the extended space

With precise engineering in place, this Oxfordshire cottage now boasts a beautifully modern, open, and spacious ground floor, perfectly suited for contemporary living while maintaining its historic charm.
