Designing ethical buildings.

Sustainability from the start of the design journey.

We have a sustainable-led approach from the earliest stages of design, when we can plan solutions that will make the greatest positive impact over the long term in both the systems and materials employed.

We’re finding more clients are actively seeking imaginative new builds, sympathetic heritage renovations and creative barn conversions with sustainability at their heart. Ethical considerations are becoming a key element of the design brief for many projects.

Ash House is one such project.

A Fabric First Approach

We design a building to the highest possible standard before considering any electrical, mechanical or technological system integrations.

By designing the fabric (sometimes referred to as the envelope of the building) to the highest standard within the brief and budget means we can minimise the future energy consumption of the building. Minimal ‘tech’ will be needed, and the tech that is employed will be designed to operate most efficiently.

Sustainability using the latest technology

Technology leads the sustainability agenda in new build design.

The use of sustainable technology when designing a new build home can limit fossil fuel consumption while maintaining comfortable ambient temperatures all year round  – this should be central to both the building and its gardens. Carefully chosen materials, site orientation and planting schemes are considered and complemented by renewable heating and cooling technologies for optimal performance whatever the weather.

How we start the design journey.
