About Us

Established in 2020, Meadows and Ross are a UK-based team of building performance professionals, consisting of Building Physicists, Chartered Engineers, and Passivhaus Consultants.

We work across the country supporting new build and existing building projects of all typologies, from single dwellings to large mixed-use developments.

Clients that we work with include architects, engineers, house builders, contractors, developers, portfolio owners, local authorities, housing associations, product manufacturers, and more.

We approach every project with a fresh outlook, tailoring solutions that fits the needs of our clients.

Meadows and Ross strikes the perfect balance of being large enough to efficiently handle your projects, yet small enough to provide a personalised, accessible service.

“From working with Meadows and Ross in both residential and commercial projects they have always shown a real knowledge and passion for sustainable architecture. They are a vital asset to any design team and can be relied upon to provide information in a timeous manner, and they are always available at the end of a phone call for some much needed advice.”
