Hire an Architect

Choosing the architect who will work with you throughout your project can be a difficult choice. An architect will design your project according to your requirements, whilst also making sure to meet building regulations. Architects are experts in turning your dream home into reality; they are trained in making the most of the space, coming up with creative ideas and solutions, and recommending reliable builders. Architect fees are usually around 15% so this will need to be considered when calculating budget allowance. As a rough guide, an average 4m x 6m extension will cost around £26,000 – £34,000.

Gain Planning Permission

Before doing anything, it is worth double checking the local planning authority regarding planning permission. In some cases, such as a small extension which extends up to 8m, will not require any permission. However, there are other elements to take into account such as height restrictions, the materials used and the amount of land covered.

Building Regulations

Even if you do not require planning permission, it is vital that all extensions comply with building regulations. You will need to ensure that any builders or contractors who carry out the work are either registered or will liaise the local building control officers to certify their work. The extension will also need to follow fire regulations.


Find A Builder

The key to a successful home renovation project is finding a reliable, trusted builder to implement the designs. Online review sites are a good place to start, you can also ask to see examples of previous work. Ensure any builders you hire are registered with the relevant trade bodies and check their warranty policies.


Hire a Project Manager

The architect and lead-builder usually serve as the project manager for the entire process, but you can also hire additional assistance if needed. The manager’s role is to ensure the project runs smoothly, stays on schedule, and adheres to the budget.

Interior Design Stage

Once the exterior design is completed, it’s time to turn your attention to the interior. It is important that the new extension flows with your existing house interior rather than looking awkwardly placed. An interior designer  will help to create a space that reflects your style and personality whilst taking into consideration the design of your existing home.
