How long does it take to build an extension and should we move out?
Homeowners naturally wonder how long it will take to build an extension because the project will create a fair bit of disturbance and disruption to your daily routine. Then there is the question of whether to move out as parts of your home become a building site. There’s a lot that goes into building an extension and here we provide more information to help you reach a decision that works for you.
How long does it take to build an extension?
Building an extension is not an off-the-shelf product, which means the amount of time it takes to build an extension varies, depending on the complexity of the build and any other unexpected complications that may arise.
If you are building a simple extension, like a 3-metre rear extension, it would take around 3-4 months for construction to be completed. Building a larger or double height rear extension could extend the build time to 6 months. You also must take into consideration the design and planning stages, which will vary depending on any planning permissions or other difficulties you may run into.
So, considering the preparation, design, planning, tender and building phases – which includes the hiring of an architect for the project – a safe estimate would be 10 months / 1 year to complete the building of an extension. Of course, there are many instances where it can be completed in a much shorter space of time, for example, building a rear dormer loft conversion can usually be finished within 6-8 weeks. The best way to get a better understanding of the completion time is to discuss the project with an architect, many of whom offer free consultations.
How to keep the project on schedule
Over the years, several stories have come to light regarding unreliable contractors who agree to take on an extension project, only to fail to keep it to schedule. This leaves the homeowner with a half-finished house, spiralling costs and no idea of when it will be finished.
To avoid this sort of problems, before any work begins on the project you should have a strong contract in place with the contractor. This should include clear cut costs for the project and a work schedule detailing start and finish dates. If you hire an architect for your extension build, they can also serve as a Contract Administrator, which includes ensuring solid contracts are in place and keeping up-to-date with the delivery and quality of the work. A good architect will be able to advise on standard forms of contract that are best suited for the type of work that is going to be done, to legally ensure that you’re fully covered.
Should I move out when building an extension?
This is a dilemma faced by many people when building an extension. The first thing to assess is the scope of work being carried out. If you are renovating the bathroom or kitchen, will these be accessible at any point and what can be used? Is demolition being carried out and is a completely isolated part of the house being worked on? If asbestos or other dangerous toxic materials are being removed you should consider moving out during this period, at minimum.
By its very nature, all construction work is disruptive, so if you believe you can continue living in your home, be aware that it will still cause inconveniences and disturbance to your routine. Many people get by with a makeshift kitchen and bathroom during an extension build, although it does take some adjustment as it could last for at least a couple of months.
Financial cost and tolerance
Not everyone has friends or family that can accommodate them for free while an extension is being built. It could mean having to pay for a short-term let or Airbnb until your home is ready for you to return to. Even if you remain in the property during a large-scale rebuild, you will certainly incur more expense due to ordering more takeaway food/bottled water etc.
If you decide to remain at home during the build, another important thing to consider is the noise and waste caused by construction work. There will be drills, hammers, electric saws, jackhammers and a whole host of tools making noise from early morning until the late afternoon, which can be difficult to adjust to. Scaffolding will be in place and more dirt and dust floating around the property as work continues.
