The value of new construction contracts fell to £5.4bn in October, a 3.8 per cent decrease on the previous month.
The UK's housebuilding sector accounts for £2bn of this contract value, according to Barbour ABI's Economic and Construction Market Review.
The largest project in October was the £350m Keadby 2 Power Station, over three times the value of the second largest project during the month.
Three of the top five largest projects in October were based in London, with the capital accounting for the largest share of contracts overall with 17.2 per cent, followed by the North West and Yorkshire and Humberside with 16.6 and 16.1 per cent respectively.
Medical and health projects reached £250m, the sector's best month for more than two years, buoyed by several public hospital projects.
Contracts in infrastructure climbed by 6.9 per cent to £1.3bn, but fell in the commercial and retail, hotel, leisure and sport, industrial and education sectors
Michael Dall, lead economist at Barbour ABI, said: "There is no doubt that the strength of housebuilding is substantially helping improve the overall figures for the construction industry.
"With a shortage of homes across Great Britain and an influx of buyers helped by schemes such as help-to-buy has propelled the sector and kept developers busy to keep up increasing expectations to build more homes. Nevertheless, as Brexit continues to be discussed and negotiated, the lack of clarity on the matter for the remaining sectors seems to have influenced the total amount and value of contracts."
