How much would it cost to rebuild my house?
The average cost to rebuild a 3-bedroom house in the UK is around £270,000. That said, rebuilding a house is a big project and there are a huge number of factors that will affect the total cost.
One of the most influential factors that will affect the cost to rebuild a house is the location. Land, property and tradespeople prices vary massively across the UK, so you need to factor that into your budget planning.
We always recommend speaking to local builders, architects and tradespeople to get quotes for accurate costs to rebuild your house.
It's worth remembering that, although bigger houses are more expensive to build, if you double the size it doesn’t necessarily double the cost.
An example of average house rebuild costs:
1,000 square feet (3 bedrooms, 2 bathrooms) – £204,000
1,400 square feet (3 bedrooms, 2 bathrooms) – £270,000
2,000 square feet (4 bedrooms, 3 bathrooms, one-car garage) – £426,000

How to calculate your home rebuild cost
There are many different variables involved with a home rebuild. So many constituent elements mean that you will often get an estimate overall for the project. The final amount may differ.
However, to help with your budgeting, you could try our handy rebuild cost calculator to give you a rough idea of what to expect.
Cost of demolition
To rebuild your house you need to knock down the existing one first, and that costs money.
The average demolition cost for a rebuild project is about £32,000, including demolition and removing existing foundations.
Again, demolition is a cost that will vary considerably in different areas of the country.
To find out more about the price of knocking down a house, check out our demolition cost guide.
House survey costs
The best way to start planning what needs doing and how much it will cost is to hire a surveyor to do a full survey of the existing house.
An average house survey costs can range from £400 to £1,500, depending on the size of the property and the complexity of the plans.
A surveyor can take detailed measurements of the house and prepare a professional rebuilding cost assessment.
That will give you a good idea of the sort of costs you’ll be looking at for the rebuild project.
To find out more about survey prices, have a read of our house survey cost guide.
Services and drainage costs
A house rebuild project involves a lot of different elements. One of the costs that many homeowners forget to include is the price of dealing with services and drainage.
Before you can start demolishing and rebuilding houses, you need to disconnect the services (water, gas, electricity, etc).
The average cost of disconnecting services is about £5,000. The cost of carrying out a survey for drainage connections is usually between£250 to £450 per survey.

Why do you need to know the rebuild cost of your house?
Knowing the rebuild cost of your house is an important part of future financial planning.
By having accurate knowledge of your house rebuild cost you can organise the right insurance coverage for your new house.
Claiming insurance after home damage

If your home has been massively damaged by an event like a fire or flood, your insurance will need to know the cost to rebuild your home.
As part of this total figure, it will need to include the cost of materials and labour all parts of a rebuild project. That includes:
Knocking down the existing property and clearing the site
Installing and connecting services (e.g. gas, electricity, lighting, plumbing, and drainage)
All permanent fixtures and fittings (e.g. kitchen and bathroom suites, fitted cabinetry)
Professional service costs (architects, surveyors, engineers and legal support)
Renovating vs rebuilding – which should I do?
Good question. But probably one best answered by an experienced local surveyor. They’ll be able to tell you exactly what is involved based on your plans and ideas for your home.

FAQs
Why does the house rebuild cost differ from the market value?
The cost to rebuild your house often differs and can even be more expensive than its market value. This may seem confusing, but there are reasons for the difference.
Structural components
One of the main reasons why a house rebuild cost can be more expensive than its market value is the use of non-standard materials and the need to create specialist architectural features.
When you’re thinking about rebuilding your house, it’s important to remember what rebuild costs will involve. Rebuilding your house will focus on the materials and labour required to rebuild the physical structure.
Although market value also reflects build cost to a certain extent, it also considers factors such as location, local amenities, and demand.
Depreciation vs replacement
Another reason for the differences between rebuild cost and market value is depreciation. When a property is poorly maintained and subjected to years of wear and tear, its market value may depreciate.
The property market is in a constant state of flux. Where demand is high, prices rise and vice versa. Therefore, market value is not a constant figure.
Rebuilding a property, on the other hand, usually seeks to restore the property to its original state. This will likely be of a higher standard than an existing property in the same area.
Therefore, costs associated with a rebuild may be higher than the market value.
External factors
External factors can also play a significant role in the cost of rebuilding a house and its market value.
The cost of construction materials, for example, can fluctuate due to economic conditions and are often unrelated to property markets.
Increases in interest rates can also cause costs to rise when considering a house rebuild project.
Will my rebuild cost change if I renovate my house?
The simple answer is yes. Renovations always seek to improve a property. Therefore, renovating a property during a rebuild project will almost certainly increase the costs.
Renovation impact
Whether you’re installing a top-of-the-range bathroom suite, a stylish kitchen or high-tech gadgetry, any property renovations will likely increase property value.
With this in mind, it’s only fair to say that the renovation costs will also increase in line with the home improvements.
If you’re planning to carry out structural changes or extend or convert an area of the property, these renovations will have the biggest impact on cost.
Updating coverage
If you’re carrying out significant renovation work as part of a home rebuild project, it’s important to ensure that you have the correct level of insurance.
As your property value increases, you’ll want to ensure that your insurance coverage is updated to reflect the increased rebuild cost.
Consulting an expert
Once your house rebuild is complete, it’s time to assess whether you need any changes in your insurance policies.
It’s a good idea to consult with an insurance agent or appraiser. They will be able to advise you whether any changes are required to ensure that all rebuild costs are covered.
What happens if I get the rebuild value wrong?
Underestimating the rebuild value of a property can cause serious problems in the future. That’s why it’s always best to get a professional valuation to ensure that you factor in all costs.
Underinsurance risk
One of the main problems of underestimating the rebuild value of a property is that you’ll likely be underinsured.
This means that in the event of a disaster, your insurance coverage may not be sufficient to fully rebuild your home to its previous condition.
Out-of-pocket expenses
The impact of underinsurance can have serious financial implications. In the case of a disaster, any rebuild costs not covered by your insurance policy will need to be paid for by you. – the homeowner.
This can lead to serious financial strain and even insolvency in the worst-case scenario. It can also be extremely inconvenient and have a detrimental impact on your home life.
Overpaying for coverage
On the other end of the scale, you don’t want to overpay for insurance that you don’t really need. Insurance coverage should be tailored to your property. An insurance agent should be able to provide accurate quotes as to your property rebuild costs.
If you over-insure your home, you’ll end up paying higher insurance premiums with no benefit whatsoever.
Annual reassessment
To avoid over-insuring and under-insuring your home, it’s a good idea to carry out regular valuations and assessments.
This is particularly important following any significant renovations. Failing to do so could mean that your finances are at a higher risk in case of unforeseen circumstances.
Importance of professional help
Seeking professional help can make sure that you avoid any financial pain and that your home has the right amount of coverage.
Hiring a surveyor or consulting with an insurance provider will ensure that you have appropriate coverage for your home’s value.
