Building with Frames Products

Sustainable Timber Frame Structures in Cornwall

At Building with Frames, we design and manufacture sustainable timber frame structures that combine structural performance, energy efficiency and environmental responsibility. Based in Cornwall, we deliver high-quality timber-based panel systems for residential, modular and bespoke architectural projects across the UK.

Our approach focuses on precision engineering, offsite manufacture and long-term performance. By manufacturing in a controlled environment, we ensure our sustainable timber frame structures achieve consistent quality, improved airtightness and reduced material waste.

Engineered Sustainable Timber-Based Structures

We design, engineer and fabricate a wide range of sustainable timber-based structures, including: Structural wall panels – Floor cassettes – Roof panels – Modular units – Garden rooms and annexes – Contemporary sauna buildings

Each system balances strength, thermal performance, acoustic control and embodied carbon reduction. Because timber captures carbon, our structures actively support lower-impact construction when compared to steel or masonry alternatives.

Modern Offsite Manufacturing

Our sustainable timber frame structures are pre-manufactured to improve efficiency and predictability.

Offsite manufacture allows us to: Protect materials from moisture – Improve dimensional accuracy – Reduce waste – Increase workforce safety – Deliver faster on-site installation

This approach results in more reliable programme timelines and better cost control.

Built for Performance & Sustainability

Sustainability is not an afterthought — it is central to our structural design philosophy.

We prioritise: Sustainably sourced timber – Low-toxin construction methods – High-performance insulation systems – Reduced steel content – Long-lasting, durable detailing

Whether we are producing bespoke architectural projects or standard modular products, our sustainable timber frame structures are designed to perform efficiently for decades.
