Barratt Developments said Britain's property market recovery was spreading beyond London and the South East, where buyers have been queuing for its new developments for the first time in years.
The housebuilder saw double-digit increases in private sales completed across its central and western regions over the year to June 30, while it added that some areas of the East and South Midlands were seeing sales rates rise by a third, with growth hitting around 50% in and around Bristol.
Its net private reservations across the UK were up by almost 30% in the first 10 weeks of Barratt's new financial year as the G overnment's Help to Buy scheme and improved mortgage availability continue to boost the market.
Barratt said buyers had been queuing since 4am for one new housing scheme at Newbury in Berkshire, with surging demand also seeing increasing numbers of people trying to buy sites before they have even launched.
The turnaround in the housing market helped Barratt deliver a 73.7% surge in annual underlying pre-tax profits to £192.3 million.
The performance prompted Barratt to announce its first shareholder dividend payment since 2008.
Barratt added that it was starting the new financial year with a 44.4% hike in its private forward order book to £880.4 million.
Mark Hughes, analyst at Panmure Gordon, said: " This is positive news going into the important a utumn selling season."
Barratt said average private property prices lifted 6% to £213,900 over the year to June 30.
A regional breakdown showed a broad-based recovery was taking hold across the UK.
Mark Clare, group chief executive, said: "We are seeing the housing market recovery starting to spread beyond London and the south east."
Average private selling prices edged 0.1% higher in London, but rose 10% in its southern region, 2.3% in the east, 6% in central areas and 6.7% in the north.
The West was the only region to see a fall in prices, down 1.5%.
Barratt said the impact from Help to Buy was "significant" , with 7% of all completions in the second half of its year and 29% of all reservations so far this financial year made through the scheme.
The initiative was launched in April, allowing those with only a 5% deposit to buy new-build homes and is set to be extended in January to existing properties.
Mortgage availability has likewise been helped, primarily through the Bank of England and Treasury's Funding for Lending scheme, which provides cheap credit to lenders in exchange for them providing mortgages as well as small business financing.
There are fears that Help to Buy in particular could lead to a housing market bubble and critics have been calling for a clear end date to be set for the scheme.
