The price of detached homes has soared by 10% in the space of a year, with buyers now paying a £200,000 premium to upsize to a bigger property.
New research by Halifax has found that detached properties are rising in cost significantly more quickly than flats, terraced houses and semi-detached homes.
Here, Which? explains why bigger properties have become more popular, and analyses how much you might need to spend to upsize to a larger home in 2021.
Homeowners living in flats spend an average of £56,000 to upsize to a terraced home, while those in terraced properties spend £85,000 to move to semi-detached homes.
The step between a semi-detached and detached home is the toughest to tackle, with buyers needing to spend £199,000 more to secure a bigger property.
Ongoing rises in house prices are making it even more difficult for upsizers. Halifax says house prices for existing home movers rose by 6.4% in 2020, compared with 4.5% for first-time buyers.
Halifax's researched focused on UK averages, but the amount you'll pay when upsizing varies significantly depending on where you live.
We've used data from the Land Registry to crunch the average prices paid by homebuyers purchasing different types of houses around the UK (equivalent data is not available for Northern Ireland).
You can use the interactive chart below to find out how much you might need to pay to move to a bigger home in your region.
House prices are rising on all types of home, but there are a couple of reasons why the cost of bigger properties is increasing so much more quickly.
Buyers are increasingly looking to move away from expensive cities in search of a better quality of life and more space.
This has been led by the likelihood that many workers will only need to commute into their office once or twice a week in the future, giving them the freedom to move further away.
The tax break means that buyers in England and Northern Ireland can save up to £15,000 when they move home - with the maximum savings on offer to those purchasing a property for £500,000 or more.
This may have led to more buyers stretching their finances to seek out a larger 'forever' home sooner than they might have originally planned.
