HollandGreen have two offices in Oxfordshire, the Oxford Office located within Prama House in Summertown as well as an office in the market town of Thame. Our team of Architects and Designers have gained a reputation for designing and delivering some of the most outstanding house extensions and renovations projects in Oxford and the surrounding area.


Our knowledge of local planning law and our close relationships with the regional planning offices also puts us in an excellent position when it comes to offering planning advice.

Almost all of our work comes from the recommendations of past clients who we have helped to realize their own home’s potential. Over the years we also built an extensive network of Oxfordshire builders who we have worked with on projects ranging from super contemporary new builds through to careful renovations of heavily protected listed homes.


Our objective is to become the first choice for anyone looking to extend or renovate their home in Oxfordshire and we feel that our Client Testimonials go a long way towards showing that that is exactly what we are doing.

So if you are looking for Architects in Oxford and the surrounding area, or are simply in need of advice or guidance when planning your new home we would love to help.

If you are thinking of starting your own project we would love to help you.  In the first instance please fill in the Developing Your Brief Questionnaire and we will give you a call back once we have had a chance to review it.  Please also take a look at our Home ConsultationFees and Disbursements and House Extension Costs pages to help you get an understanding of the likely costs moving forward.  

Please note: as a general ‘rule of thumb’ HollandGreen’s fees tend to work out at around 8-12% of final build costs and our projects typically have a construction cost of between £250,000 and £2,000,000.
