Something we are asked frequently here at Lewis Visuals is “How long will my extension take to build?” This one is much more difficult to answer than “How much will my extension cost?” but it is one that we do our best to provide an answer to. When building an extension, there are certain aspects of the build that take a specific amount of time and there are other aspects that are unknowns or factors that could takes days, weeks or months depending on the build.
Any time you plan a build project such as an extension, there are certain factors that play a role in the length of time it takes to complete the project. Let’s take a look at some of these factors and the average length of time it takes to complete each one:
Choosing a design team-1 month
When adding an extension to your home, you want to find the right design team that is experienced in creating the type or style of design that suits your needs. This could take up to a month or longer.
Project Design-2 months
Once you have chosen your design team, they will get to work creating a design that suits your home and your style. You will receive an initial proposal within a week or two and the entire design phase could take up to two months depending on your requirements.
Depending on where your home is located, you will need to submit your plans to the local authority planning department for approval. This could take up to 8 weeks or longer depending on the complexity of the plan.
Building regulations-2 weeks
Now that the plan is approved, more detailed plans need to be created following building regulations. Expect this to take an additional 2 months.
Choosing your builder-1 month
It could take up to 1 month or longer to choose the right builder for your project. Then, that builder will need to look over the plans and create an estimate.
The construction phase could take up to 4 months as it contains factors that could speed up or slow down progress. Larger extensions could take 6 months or longer.
Finishing and Trimwork-2 months
Although your extension may look move-in ready from the outside, there is still finish and trim work that must be completed for the project to be finalised. Depending on the size of the project and homeowner requirements, this could take 2 months or more.
