A sauna or wellbeing space should not simply look beautiful. It should feel healthy. It should support recovery, breathing, relaxation and connection to natural materials. When the body heats up, circulation increases, pores open and breathing deepens. During sauna bathing or exercise we naturally inhale more air, more deeply and more frequently. That makes the quality of the environment around us even more important.

Many modern buildings can contain high levels of glues, plastics, sealants, formaldehydes and chemically treated materials that may release volatile organic compounds (VOCs) into the air — particularly when exposed to heat.

We take a different approach.

Our saunas and wellness spaces are designed around the principle of healthy breathable buildings using carefully selected natural materials with low toxicity and minimal off-gassing wherever possible. From sustainably sourced timber interiors to premium Scandinavian heaters and carefully considered construction methods, every decision is made to create a cleaner, calmer and more natural environment.

The result is a space that feels different the moment you enter:

• the warmth of real timber
• the subtle natural scent of wood
• clean breathable air
• a calming acoustic softness
• and a deeper connection to nature and wellbeing

We believe wellness architecture should support both physical and mental recovery. Whether you are stepping into a sauna after exercise, slowing down after a stressful day, or creating a wellness retreat for guests and family, the environment around you matters.

Our modular wellness buildings combine:

• sustainable construction
• precision offsite manufacturing
• low-emission materials
• natural breathable finishes
• uncompromised thermal performance
• and timeless Scandinavian-inspired design

Our wellness spaces are designed with long-term health, comfort and durability in mind.

Because true luxury is not only how a space looks — it is how it makes you feel, breathe and recover.

At Building with Frames

We are creating healthier spaces to live well.

At Building with Frames, we design and manufacture sustainable timber frame structures that combine structural performance, energy efficiency and environmental responsibility up to Passive House standards. 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.

Designed, Manufactured & Delivered from Cornwall

From our Cornwall base, we support architects, developers and homeowners seeking high-performance timber construction solutions.

If you are planning a modular build, annex, bespoke home or specialist timber structure, our team can guide you from concept through to delivery.
