Building Better Homes for Comfort, Health, and Energy Efficiency
If you’re exploring a Passive House project or want to create a healthier, low-energy home, Deansmead specialises in sustainable construction that puts well being first. We combine proven building methods with a fabric-first approach, working alongside homeowners, architects, and sustainability consultants to deliver projects that are energy-efficient, comfortable, and built to last.
We collaborate with experienced consultants — including partners like Sustain Change — to help clients meet ambitious energy performance and environmental goals. Whether it’s Passive House standards or a healthy home retrofit, this joined-up approach means every element is considered, from airtightness and ventilation to materials selection and building performance.
Airtight construction reduces heat loss, improves comfort, and cuts energy bills — but it only works when paired with the right ventilation strategy. We carefully manage both, helping create homes that are warm, efficient, and healthy to live in.
We often use Structural Insulated Panels (SIPs) for their superior airtightness and thermal performance. We select panels with low or no VOC content, supporting better indoor air quality and reducing harmful emissions inside the home.
We favour natural insulation materials like wood fibre, hemp, cork, and sheep’s wool — breathable, sustainable options that help regulate humidity, reduce condensation risks, and promote a healthier indoor environment.
From Passive House-inspired detailing to robust insulation and airtightness, we take a fabric-first approach to every build. Whether it’s a new home, extension, or retrofit, we design for energy efficiency, comfort, and durability — helping clients achieve their sustainability goals.
If you’re thinking about a Passive House, healthy home, or sustainable building project in Sussex, we’re here to help. Deansmead works closely with clients, architects, and sustainability consultants like Sustain Change to deliver projects that balance comfort, energy performance, and environmental responsibility.
