House Extension Costs

The cost of a house extension can very massively. There are so many variables to consider. To provide a very rough guide, we have put together some example costs of various house extension projects.


Glazed Gable End

Glazed gable ends are a great way to increase natural light into a room by maximising the amount of glazing. They can add an attractive feature to your extension. This article explores some of the things to consider when including a glazed gable in your design.


Loft Conversion

Converting your existing loft space can be the most cost-effective way to create an extra room, or even an extra storey, in your house. This article covers some of the options for roof types, stairs, and roof lights.

Project Stages

The stages below are for a typical house extension project.

1. Survey Stage

You will be required to measure your house and produce a survey sketch (this is much cheaper than having an Architect visit your home with a tape measure!). Survey sketches are really easy to produce, and they just need to show the layout of the house, room names and sizes, door and window positions. Click Here to see some examples.

2. Design Stage

Drawings are prepared showing the existing and proposed house. The proposed drawings will be based on your ideas, sketches and any example images you send. We will help you refine your ideas and suggest alternatives. Take a look at our Articles section for some ideas and design inspiration.

3. Planning Application

Some projects would fall within the rules of Permitted Development and therefore do not require a formal planning application. All other projects must be submitted to your local council for review. The Planning Application will require details of proposed finishes, materials, and the exact dimensions of the scheme.

4. Building Control

A Building Control package (also known as Building Regulations) is a set of drawings and a construction specification for every aspect of the project (such as thermal insulation, roof construction details, foundation types, wall build-ups etc…) We can help with this stage even if you didn't use us for the design and planning stages.

5. Structural Design

We can also prepare the structural design for your project and submit it to the Council as part of the Building Control application. This will include all the structural information required by your local authority to sign off the Building Control application, your builder will also need the structural design package for them to follow during the build.

6. Project Completion

The project is handed over to your chosen builder. During this stage, the Council will visit the site and inspect the work to make sure it adheres to the Building Control package. We will provide design support for the duration of the project and are always on hand to provide advice if required.
