Large New Build Development – Bolton, Greater Manchester
This new build home in Bolton was carefully designed to combine structural efficiency with modern aesthetics, featuring a large loft space and a duo-pitched roof, all constructed using timber engineering solutions. The goal was to create a spacious, energy-efficient home, making the most of the available roof space while ensuring structural stability and long-term durability.
To achieve this, PorthouseDean provided expert structural calculations, ensuring that the timber framework, pitched roof, and loft design were engineered for safety, compliance, and efficiency.
Maximising Space with Smart Structural Design
This new build included:
✅ A large loft space – Providing additional living space with an open, airy feel
✅ A duo-pitched roof – Optimising headroom while maintaining structural stability
✅ Timber engineering – Offering sustainability, strength, and design flexibility
✅ Efficient load distribution – Ensuring durability without unnecessary overengineering
What we did
Our contributions to this project included:
✔ Structural calculations for the timber loft structure – Ensuring compliance with Building Regulations
✔ Timber beam & joist design – Supporting wide spans while keeping the structure lightweight
✔ Roof pitch stability analysis – Ensuring the duo-pitched roof remained strong and resilient
✔ Load-bearing wall & foundation assessments – Distributing weight efficiently for long-term durability
With expert calculations in place, this Bolton new build now benefits from a secure, energy-efficient, and architecturally impressive loft and roof structure, designed for modern living and long-term performance.

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.
