Fees Associated with Your Project

Whilst every Project is unique the first question we are often asked is ‘What do you charge for a set of plans?’ This is very difficult to answer as no two Projects are the same, however we have tried to outline what a ‘typical HG’ project may cost.  Our aim is to be totally transparent at the outset and not conceal potential costs – we are not the cheapest option available but certainly not the most expensive. We firmly believe that our Team offer an unrivaled service and a unique level of experience when it comes to designing and delivering the best extension and renovations and new homes in Surrey, South West London, Oxford, Buckingham and Berkshire areas.

HollandGreen work on an hourly rate (£85 +VAT per hour) and as such have given indicative ranges of what you might expect for the various stages of a project. Factors that might effect this range will be such things as the complexity of your project, any unusual elements in terms of design and restrictions or indeed how many options you may wish to explore. As a general ‘rule of thumb’ our fees tend to work out at around 8-14% of final build costs and a typical HG project can have a construction cost of between £200,000 and £2,000,000.  The guide below is supposed to be exactly that, a guide; a Home Consultation will allow us to give you a much clearer understanding of potential designs and likely costs.
