Adding an extension to your home is a great way to add value, increase your home’s space and improve its street appeal.

Before you launch into adding an extension, it’s important to do some planning. Here’s some tips on how to design an extension for your home:


The first step is to think about what you want to achieve in the extension. Would you like to add more bedrooms for your growing kids, create a study space, make room for grandparents to stay?

Dream a little, then come back to reality. Ask yourself what is the highest priority and whether you can afford it or not.


Once you’ve done some planning, it’s time to think about the design. Get an architect, interior designer or renovation company to draw a detailed design for you.

Think about layout, functionality and style. How will your house flow into the extension? Try to blend new into old through using the same colours, materials and fittings on doors, walls and windows. Also consider the existing architectural style, and whether it’s modern, traditional or historical, as this will affect the design of your extension.


Before you start building your extension, you will need to get permission from local authorities. They will need to ensure that your planned work will comply with the Building Code and meet electrical and safety regulations.

It’s also a good idea to talk to your neighbours at this stage and make sure that they don’t object to your extension.

Get a Quote

Once your extension has been approved, you then need to get a quote. Renovations can be expensive, and it’s important not to rush into it and blow your budget. Make sure you talk to different builders and get multiple quotes to compare prices.

The final price will depend on how complex your project is, how much demolition and construction is needed, the materials used, and how difficult it is to access your site.

Choose a Builder

The final step is to choose a reliable building company to build your extension. Make sure they are qualified and hold the necessary licences. Look at reviews of their previous work to get an idea of their quality and reputation.

It’s a good idea to look for a builder who specialises in extensions and has experience in the architectural style of your home.
