Sustainability Award - Earl and Calam Design and Build Ltd (London)

The judges hailed this extensive retrofit renovation as a “well-considered project [that] put fabric-first at the heart of the design”. The team at Earl and Calam Design and Build embarked on specialist training specifically to do it justice. The results are evident in the abundance of green technology throughout the home including passive solar panels, external wall insulation (EWI) and the implementation of a Mechanical Ventilation with Heat Recovery (MVHR) system. The judges also noticed the significant improvement in the overall aesthetic at the property, which is now a stylish, modern, and energy efficient family home.

Sustainability Award - Carrock Homes Ltd (Northern Counties)

Carrock Homes Ltd were more than up to the challenging task of converting this historic cruck barn into a modern, energy-efficient family home.

This Master Builder’s diligence impressed the judges and their client, who stated: “Carrock have more than accommodated our lifestyle needs and wants beyond our expectations.”

Sustainability Award - Spey Building & Joinery Ltd (Scotland)

Undertaking the repurposing of this old packing shed into a creative design studio in a remote location, the team at Spey Building & Joinery lived locally throughout this project. Trips to the site were minimised to just one per week, and rather than demolishing the existing structure they instead repurposed it, which helped to reduce waste. Spey alternated between using birch-faced plywood and common house brick for the walls and flooring, which contrast well and provide a simple, yet effective and durable solution. The client stated: “Angus Reid-Evans, director of Spey Building & Joinery, is approachable, cheery and practical” and praised the team for bringing “friendliness and understanding” to the build.

Sustainability Award - Mitchells Construction & Development Ltd (Southern Counties)

When Mitchells Construction & Development were contacted by an environmental rights campaigner looking to build their dream eco home, they rose to meet the challenge and overcame ground quality issues to delight their client. Located on a nature reserve and carefully designed to blend with and complement the surrounding area, the house makes use of sustainable features such as rainwater harvesting and recycled insulation material to ensure a harmonious relationship with mother earth. “I have a home for the future that uses minimal resources and is part of and aids its habitat” says the new owner, and we’re going green too – with envy!

Sustainability Award - Chris Noakes Construction (South West)

Following the demolition of the existing bungalow, Chris Noakes Construction undertook the creation of this insulated, two-storey timber-framed and strawbale house using almost exclusively locally sourced materials. Acting on their client’s brief to design and build a sustainable, attractive and comfortable new home, the team installed an array of solar panels, natural ventilation channels and made use of breathable fabrics to maximise energy efficiency. Both the build process and the results delighted their client, whose testimonial reads:

Chris and his team are professional, diligent and great to have around… The house has exceeded my expectations on every level. Thank you so much."
