Extensions are a cost-effective way of increasing the size of your home without the need to move out of the area you like. At WHS Associates we have been producing designs and project management for home extensions since 1989. We cover Epping and the surrounding areas in Essex and London.

We have considerable expertise in the planning and design of extensions and have developed excellent relationships with local authorities and local building contractors to make sure that you get the best possible service. We will listen to your needs and advise on all the options available. Contact us to arrange a free initial consultation.


We will help you decide the best approach in achieving your accommodation needs by offering a combination of good design ideas and value for money. We have a very high success rate in gaining planning permission and offer a discount on RIBA (Royal Institute of British Architects) prices, giving you value for money without compromising on quality.

At WHS Associates, after a free on-site consultation, we carry out a full measured survey of your existing property, prepare plans and sketch design options within your budget.


If planning permission is required we will submit the application for you and deal with the consultation with the local authority, making any alterations free of charge if they are required. Once consent has been obtained we will prepare the construction drawings and specifications for Building Control approval and again consult and negotiate with the Local Building Control Officer.

Our success rate is very high and once all the formalities have been completed we can obtain competitive tenders from local contractors. We can recommend high-quality contractors to make sure that everything runs smoothly from start to finish.
