We are a leading residential architectural, interior design and landscape and garden design practice covering projects across the Cotswolds, London, Home Counties and South Coast. We share a passion for delivering inspirational, insightful design, covering a range of styles, from contemporary new builds, to large-scale home renovations and extensions, as well as listed buildings, barn conversions and heritage properties. Our successful experience with Permitted Development Rights, Class Q conversions, Conservation Areas and AONBs enables us to show you at an early stage what it is possible for you to achieve. Using immersive 3D modelling and virtual reality, we can then help you visualize and create your ideal home, adding both space and value to your property. Our commitment to design excellence means our team are all as excited about your project as you are. We aim to be approachable and plain speaking, encouraging your collaboration and involvement.

"HollandGreen have brought our house to life! Their interactive 3D model has helped us to imagine what 2D drawings will eventually look like. The ability to walk through the house room by room and looking through windows gave us a very real impression of our project well before the build had even started. It enabled us to personalise the design in a way that 2D drawings wouldn’t have allowed." Fiona, Buckinghamshire

We have no hesitation in strongly recommending this highly professional, flexible and assiduous firm." Sir Brian & Lady Victoria, Oxford
