The FTSE 100 group, which also owns the David Wilson Homes brand, said it had sold 750 new homes in the area during the past financial year, worth almost Â£172 million. The record number of sales has led to an increase in revenue of more than 16 per cent compared to the previous 12-month period.
Barratt said the figures underlined the continued demand for quality new homes in Edinburgh and the Lothians.
One of the builder’s most successful developments has been The Kilns at Burdiehouse to the south east of the capital with 52 of its homes sold over the course of the year. It said the Scottish Help to Buy scheme had remained an important factor in its success, taken up by buyers in about a fifth of all sales.
Alison Condie, managing director for Barratt East Scotland, said: "During a period of economic uncertainty caused by the elections and the Brexit vote, we've been really pleased by the sustained sales across our developments in and around Edinburgh.
"Whilst Help to Buy undoubtedly continues to provide a huge stimulus to the housing market in Scotland, buyers have been attracted by our range of house types and developments available. We expect that the market will continue to remain buoyant over the course of the year."
The group is on course to open seven additional sites in the east of Scotland during 2016. Recently launched developments include Dovecot Mill in Haddington and both Westerwood Gardens and Liberton Grange in Edinburgh.
