Larger homes are driving house price growth across Britain, new data from Halifax has revealed.
Detached properties have increased in value by more than £100,000 over the last five years, the lender’s research found.
They currently sell for an average of £471,748 – just shy of the record high set in September 2024 at £472,984.
Back in 2020 they sold for £363,869 meaning they have seen a rise of 29.6 per cent or £107,879 – the strongest growth of all property types.
Flats went up in value the least between 2020 and 2025, perhaps due to buyers’ desire for outside space during the pandemic. They rose by 16.7 per cent or £24,133 to to £168,569.
Terraced homes went up by 26.7 per cent to £235,296.
In the last year, though, terraced homes have outperformed detached ones. They saw annual price growth of 4.5 per cent or £10,025, reaching an average of £235,296.

Detached properties rose by 4.1 per cent or £18,704 across 2024 to reach the new £471,748 average.
By contrast, flats saw the slowest growth at 3.2 per cent, with an average price of £168,569.

Across Britain, property prices increased by £10,431 or 3.7 per cent during the period, bringing the average cost of a home up to £294,818.
The £294,818 figure surpassed the previous peak in August 2022 during the pandemic-era property boom.
Northern Ireland recorded the strongest annual growth for detached properties, seeing a rise of £35,857 or 15.2 per cent. In London, detached homes saw growth of just 0.9 per cent.
The average cost of a detached property in London, where they are most expensive, stands at around £944,526, Halifax said.
This is around five times more than the cheapest location, the north east of England, at £190,757.

Gulf: Average house price gap between different property types, according to Halifax
Terraced homes led house price growth for much of the last year, peaking at 5.7 per cent in October 2024. ‘They began 2025 at +4.5 per cent, with the average price now at £235,296, up by £10,025 over the last year’, Halifax added.
Price growth for flats fluctuated significantly over the last year, from 1.3 per cent in January 2024 to a peak of 4.7 per cent in October, before easing to 3.2 per cent at the start of this year.
Regionally, the north east saw the strongest growth in flat prices, rising by 15.1 per cent or £13,141 to £100,123, while the east midlands experienced a slight decrease of 0.6 per cent or £705.
On the gulf between costs for different property types, Halifax said: ‘Since the turn of the century, the cost gap between different property types has widened significantly.
‘In the year 2000, the cost of the average flat was just £49,905. An extra £9,105 would get a terraced house, a further £22,006 a semi-detached house, and an additional £51,655 on top of that would secure a detached property.
‘Fast forward to 2025, and the cost of the average flat is now £168,569. An extra £66,726 would be needed for a terraced house, a further £72,389 for a semi-detached house, and another £164,063 for a detached property.
‘However, in relative terms, the cost of a flat compared to a detached house – a measure of the gap between the rungs of the housing ladder – has only increased slightly from 2.7 times in 2000 to 2.8 times in 2025.’
Halifax said the first-time buyer market ‘rebounded’ last year, as a fifth more buyers stepped onto the property ladder, buoyed by slightly lower mortgage rates.
Buyers of new-builds continued to pay a significant premium compared to existing properties, at £33,514 overall and up to £71,865 for flats.
Amanda Bryden, head of Halifax Mortgages, said: ‘The fortunes of different property types tend to ebb and flow depending on broader market conditions.
‘This time last year, the average price of a flat had risen more quickly than a detached house, as buyers adjusted to higher borrowing costs and sought to compensate by targeting smaller properties.
‘Now, as interest rates have started to ease, it’s once again those homes offering more space which are fuelling demand.’
