SELF BUILD HOMES
WITH AC ARCHITECTS

Are you interested in building your own dream home? Well, Allan Corfield Architects (ACA) are perfectly suited to provide the required architectural services for your project.

We provide a tailored service to suit our clients’ needs. As each client has their own individual requirements, it is paramount we develop a close working relationship with our clients – in order to successfully achieve your Self Build dream.

This relationship begins with a free initial ACA consultation, as we feel it is important to meet with all potential clients, and develop an impression of what their dream home consists of. In understanding the way our clients live, ACA can deliver a bespoke proposal to match the specific wishes of each and every client.

However, at ACA we also understand the difficulties faced by the first time Self Builder.

We endeavour to guide them through each stage of their project – offering a service that goes well beyond the initial design process.

From the traditional parts of the architect’s role – such as the planning, building control and technical drawings for the Self Build – right through to developing a build schedule and engaging with sub-contractors, ACA assist and educate the Self Builder throughout the build process.

When ACA provide a Fee Proposal for a new house project, the required services are split up into logical stages. These have a fixed cost and an advised timescale. The RIBA suggest that an average fee for this type of project would equate to between 8-10% of the overall Construction Cost. At ACA, we believe our clients should know all of the main facts and costs before committing to a project, so we work on a fixed cost rather than a percentage – that way our fee isn’t determined by how expensive your build is!

Additional Info
Pre-application Planning Enquiry

If your project is contentious or doesn’t comply with Permitted Development it may be worthwhile getting pre-application planning advice. Some planning departments will discuss the proposals over the phone, but due to workload most of the Councils now require a formal application. A Pre-Application enquiry is a cost effective route which will give you a formal response from the planning team. The process usually takes 21 days and shouldn’t cost any more than £160.

Structural Engineer Services

You will need an Engineer for the Building Warrant Stage. The engineer will access the ground condition, before designing the foundations and the super-structure for the new house. They will also provide any calculations required in order to satisfy the building warrant application. AC Structures basic engineering costs for a typical house should be approx. £5,000 (ex VAT).
