Timber Frames & Supply Options in Portsmouth
We support two main service types:
- Full supply and installation of timber frame systems
- Supply-only trussed rafters and floor joists (easi-joist®)
Every project benefits from detailed CAD designs using Wolf Systems software and expert technical input throughout.
Merronbrook’s high-performing timber frames help reduce time on site and improve build efficiency.
Trussed Rafters and Attic Trusses
Roof solutions are a core part of our service.
Our Portsmouth clients rely on us for:
- Engineered trussed rafters tailored to your roof design
- Attic trusses for creating cost-effective room-in-roof living spaces
Attic trusses maximise usable space without extending the footprint, which is ideal for properties in denser urban areas.
Floor Joists and Roof Joist Systems
Our metal web easi-joists® are perfect for modern builds requiring long spans and easy service access.
Whether you’re building flats, houses, or extensions, we offer:
- Metal web floor joists
- Flat & pitched roof joists
Our floor and roof systems improve speed of construction and long-term structural performance.
Why Choose Timber Frame Construction?
Off-site timber frame construction brings major advantages:
- Predictable lead times
- Clean and quiet on-site assembly
- Reduced waste and labour
- Improved thermal and energy performance
It’s a popular choice among Portsmouth developers and self-builders looking to build sustainably and efficiently.
Environmental Benefits and Thermal Performance
We focus on minimising environmental impact through responsible timber sourcing and efficient fabrication.
Our systems are designed to reduce thermal bridging and meet or exceed SAP and Building Regs performance targets.
The result: warmer homes, reduced heating costs, and long-term energy savings.
