Each house will have three bedrooms and wood burning stoves
A Lincolnshire council has been granted planning permission to build two semi-detached, affordable homes made from straw.
North Kesteven District Council claims to be the first UK local authority to use straw technology for its housing.
The two homes, which will cost £110,000 each to construct, will be built at West Grove in Martin.
The houses will be built using straw bales in the structure and the walls will be plastered with lime.
The three-bedroom family homes will look like conventional brick built properties and have been designed by Amazonails, a straw-bale builder based in Todmorden, West Yorkshire.
Leader of North Kesteven District Council, Councillor Marion Brighton OBE, said: "The district council not only hopes to share its expertise and knowledge with other organisations but also with residents by inviting them to come and watch the whole process of the houses being built.
"The straw houses are the first of their kind to be used as social housing in the country and are one of the ways the district council is providing much needed affordable housing."
Due to the high insulation values of straw, the properties will be up to three times better insulated than building regulations require, according to the council.
They will also not need heating systems but will have wood burning stoves installed for very cold weather.
A spokeswoman from the council said construction on the new houses would begin "very soon".
