Built light. Built to last.
Sustainability at Soleta is the starting logic of every decision — material selection, structural system, foundation approach, energy strategy. The choices compound: a home built from natural materials, on carefully considered foundations, with a high-performance envelope, designed for 80 years of use, is sustainable in a way that no single specification can claim on its own.
We do not use the language of net-zero, carbon-neutral, or eco-friendly. Those terms have been diluted beyond useful meaning. What we can say precisely is what the materials are, what they store or emit during production, how long the building is designed to last, and what energy strategy is applied — and we say it with the qualifications those statements require.
Sustainability, for us, is primarily a design and materials discipline. The most sustainable building is one that does not need to be replaced, does not require synthetic maintenance products, and does not impose ongoing mechanical complexity on its occupants. That is the standard we design to.
Carbon stored, not emitted
Timber is the only mainstream building material that stores carbon rather than emitting it during production. A Soleta home stores approximately 30–40 tonnes of CO₂ in its structure for the lifetime of the building — a figure that varies with home size and timber volume. Steel and concrete construction of equivalent programme typically emits 80–120 tonnes of CO₂ in production. The contrast is structural, not marginal.
97% organic materials by mass
By mass, 97% of the materials in a Soleta home are of organic or natural origin — structural timber, insulation materials, natural finishes, stone. No EPS foam, no mineral wool, no synthetic membranes. At the end of its life, a Soleta home can be almost entirely composted, reclaimed or recycled. That is a consequence of material selection made from the start, not a retrospective claim.
Minimum site disruption
For some Soleta models, ground screw foundations are recommended. They are installed without excavation — typically one day's work that leaves the soil structure, drainage and root systems of the site undisturbed. No concrete poured, no spoil removed, no permanent alteration of the ground profile. Where site conditions require a different foundation approach, it is specified clearly at the engineering stage.
Energy strategy starts with the envelope
The ZeroEnergy approach begins with insulation, airtightness and glazing orientation — not with the size of the solar array. A well-designed envelope dramatically reduces energy demand before any renewable system is sized. Where ZeroEnergy systems are installed, they are sized to the actual demand of the specific home on the specific site. Performance depends on location, orientation, use pattern and installed systems.
Designed to last 80 years or more
The most sustainable building is one that does not need to be replaced. Soleta homes are designed with an 80-year structural design-life target — with structural systems that can be repaired, extended or reconfigured rather than demolished. Actual service life depends on specification, site conditions and maintenance. The timber frame improves with age when maintained correctly. That maintenance programme is part of what we offer, not an afterthought.
Responsible sourcing and local production
Structural timber comes from certified European forests, especially from Sweden. We make every effort to reduce transport distances to our main project markets. For very distant markets, we work with regional material suppliers and local craftspeople wherever the quality standard is met. Certification and sourcing documentation is available on request.
A building that lasts 80 years without requiring replacement, major retrofit or synthetic intervention is more sustainable than one that achieves a certification at the point of completion and deteriorates thereafter. We design for performance over time — which means specifying materials that age well, detailing junctions that do not allow moisture accumulation, and maintaining the homes we build through a structured aftercare programme.
