Average selling prices on private sales increased by 6.5% to £197,000 against a backdrop of broadly flat house prices in the wider market.
The firm said it was optimistic about the year ahead with the value of its order book at the end of the year 14% higher at £948m.
Pete Redfern, chief executive, said that sales rates and visitor trends had improved in recent weeks, particularly in the South and Midlands.
He added that the firm had also seen a noticeable increase in the number of NewBuy reservations in the first eight weeks of the year.
“During 2012, we’ve continued our consistent approach and focus on margin and returns, delivering a significant increase in profits.
“These results show the benefit of our short term land and strategic land asset choices, along with our sharpened focus on capital efficiency.”
Redfern added: “It is too early to predict the market for the year and we believe that mortgage availability will remain the key constraint on the market, although we have seen improvement over the last few months and hope that this will continue.
“This combined with a tentative improvement in consumer confidence, gives us grounds for cautious optimism in the short term.”
