Chief executive Greg Fitzgerald said: "The half year saw strong performance across the group and we have been very encouraged by the start of the calendar year. Group profit for the half year is at a record high and we continue to be encouraged by the levels of future opportunities. "Housing market conditions continue to improve with Linden Homes revenue rising 20% and good progress is being made on our margin enhancement plan. In the first six months of the financial year we have secured a significant increase in our landbank and the land market remains generally positive. "As previously indicated, we have realigned Galliford Try Partnerships within housebuilding so as to maximise the significant potential of our strong presence in the affordable housing market. "In construction we have increased our order book as our businesses continue to perform strongly in the current market.
