Team members took part in the ceremonial cutting of the first turf to mark the start of construction at Manor House Park, off Church End. The first homes will be ready in early September.
The new development will see 58 3, 4 and 5-bedroom homes built in the sought-after Bedfordshire village.
David Thomas, Kier Living Eastern sales and marketing director, said: “We are delighted to have started work on Manor House Park.
“These superb homes in Biddenham will be perfect for couples, expanding families and those looking to downsize.”
