Step 1: Permissions

Once you’ve decided on the type of extension you want (rear extension, loft coversion etc) you 'll next need to consider whether or not you are permitted to build it. Either planning permission will be required, or your plan will be accepted within the rules outlined in permitted development rights. 

Also known as PDR, permitted development rights are the entitlement to modify a property without the requirement of applying for planning permission. Instead of being authorised by local planning authorities, the rights are issued by parliament.

Planning permission is required if the proposed extension doesn’t fall within the categories outlined in the permitted development rights.

Planning permission is the acceptance by the local authority to go ahead with the requested construction plans of a building.

Step 2: Appoint an architect

Who will produce detailed drawings to submit to your local council and Building Regulation Officers. You'll need to wait for approval (which can take anywhere between a few weeks to a few months.)

We work with a number of reputable architects who we can recommend.

Step 3: Work on an interior and exterior design

Employ a designer to produce detailed 2D and 3D visuals of your finished product. They’ll also be able to advise on design styles to meet your budget.

In most cases an architect will only produce detailed plans for building works intended to provide your chosen construction firm with key details on how the build must be carried out to meet regulations.. These plans however do not include adequate information to provide an accurate quotation for construction of your shell structure and internal works (kitchens, bathrooms, floor finishes, ceiling finishes etc.)

Step 4: Budget your project

Alongside design work, start thinking about a realistic budget for the works. Most importantly consider the maximum you can afford to pay. We recommend that your finished plans are accurately quoted by a design and build specialist who'll consider the costs related to all aspects of your construction from building materials to interior finishes.

Step 5: Shake hands and contract the work

Once you've decided on a construction firm and accepted their quote - sign a contract detailing a schedule of works, a payment plan and a proposed timeline for the delivery of your project. At this stage you'll also need to think about agreeing start dates - depending on the availability of your contractor.

Step 6: Building Control and The Party Wall Act

You'll need to employ building control. This can either be through your local council or via a private firm. Neighbours must be informed of any proposed work in advance. You'll need to provide a minimum of 2 months notice by serving a party wall notice.

Step 7: Home Insurance

It is strongly recommended that you inform your home insurance provider with details of your scheduled work.

Step 8: Construction begins

Building control will need to be informed when construction work begins. They'll work closely with your contractors to ensure that all works carried out and outlined in your architectural plans are compliant.

Step 9: Sourcing materials and managing timelines

You should have regular communication with your contractors during the "build phase" of your project. Any deviations from the works or timelines must be communicated by both parties to avoid disputes. If your contract states that you'll be providing certain materials (e.g. bathroom fittings, kitchen units etc,) you must make sure these are ordered in time and delivered on site to prevent delays in the work schedule. This process can be time consuming and stressful for parties who have had no prior experience with managing a project.
