Holland and Green was born out of a belief that we could do better – much better. We founded a Company that specialised in designing the best house extensions and renovations and new homes – and nothing else. By recruiting bright and forward thinking Architects and Technicians from within the industry we have broken the process down into its various stages and created a new client focused business model. It is based on easy access to information, better communication delivering a better customer experience through innovation and 3D modelling,

Our use of the latest technology, immersive 3D design and animation means that our clients get the chance to see how their finished house will look at the earliest stage and as it develops, you will be asked for feedback at every stage and we will work with you to generate a design that you can see in 3D and understand before a single foundation is dug or timber cut.
