Creating inspirational spaces that work around you (and don’t cost the Earth!)
Drawing on expertise and understanding of sustainable design and healthy living environments, Evergreen Design Studio specialises in low energy family home design, one-off houses and small bespoke housing developments. We are firm believers in creating spaces based around users which are filled with natural light, create framed views and link inside with outside to unlock the potential in every property and give users an uplifting ‘wow’ moment every time they come home.
We are passionate about low energy design and specialise in both new build dwellings and converting and/or retrofitting existing properties to not only improve their energy efficiency and living environment, but also to optimise their plan and functionality for the end user to realise their full potential.
We believe in the power of collaboration to create exceptional architecture. We work closely with you to develop a design that creates an inspirational space that works for you and minimises environmental impact as well as energy bills. We spend time to understand your vision and goals and develop a design that reflects these but exceeds your expectations.
