Our London Office is now co-located with our Surrey Office in Hampton.

HollandGreen have a wealth of experience helping our clients fulfill their dreams to extend or renovate their properties in West and South West London.  We are very proud to have had projects recently showcased in both ‘Grand Designs’ and ‘Homes and Gardens’ Magazines.   Much of our work comes from referrals and it is our focus on the single aim of Creating Wonderful Living Spaces that has earned HG an enviable reputation as ‘the place’ to have your Extension or New Build Home designed and brought to life.


By being totally client focused and concentrating purely on residential work we have an intuitive understanding of our clients desire to generate more space and yet remain within a realistic budget.  Our knowledge of Local Planning Law – which differs between Councils – together with a Back Office Team that have developed strong relationships with the various Planning Officers puts us in a strong position when you just want to know what is or is not possible: Inside Conservation Areas? Buildings of Townscape Merit? Grade II listed and Permitted Development Law add complexity that we love to unravel.


We are aiming high – to be the first choice for anyone looking to extend their property in London and Surrey – and if you take a look at our Client Testimonials you’ll see we’re hitting our target.  You are in safe hands with HollandGreen, so if you are planning any sort of Extension, Renovation or New Build project and want some friendly and accurate advice please get in touch – we’d love to have you write our next testimonial.
