Planning an extension or conversion is a vital step in the construction process. Without a bulletproof plan, the whole project could derail at any time. The best way to plan an extension or conversion is to sit down with your contractor or an architect to draw up plans.

When planning an extension or conversion consider the following points:

• Do you need planning permission?

• What is your budget?

• How big will your extension be?

• Will your project comply with building regulations?

• How do you want your extension or conversion to look?

• What tradespeople do you need to work with?

• How will you source the necessary materials?

• Will you run the project yourself or hire a project manager?

How long does it take to build an extension or conversion?

This will vary depending on the scope of your plans. For example, a bathroom conversion may take two weeks, while a double storey house extension could take months.

Once you’re ready to go ahead with your exciting project, you’ll need to hire an extension builder and other tradespeople to carry out the work.

It can be difficult to estimate just how much an extension or conversion costs. This is due to the many factors that affect the amount you pay. Below are some of the things to consider when estimating the cost of your extension or conversion:

• Extension or conversion?: Extensions often take longer and are more labour intensive than conversion so can be more costly

• Scale of your plans: If you’re making minimal changes to your home it’ll be much cheaper than extending the entire rear and side of your property

• Location: Depending on where you live in the UK, this could affect your conversion or extension cost

• Quality of materials: The higher quality of materials you choose, the more expensive your renovations will be

• Planning permission: If you do need planning permission, this is an extra cost

• Access: If your home is difficult to access, labour times will increase and so will the total amount you pay
