Cuddymoss beat three other shortlisted buildings to win Rias’s Doolan award, which has been given to Scotland’s best building since 2002.
The designers said they wanted the additions to the agriculture building to blend in as much as possible with the 200-year-old structure.
They added silver-toned timber cladding to the original stone-built ruin in an effort to allow it to continue to blend into the surrounding countryside.
The owner said he felt more like a custodian of the building than its owner.
The designers said they worked with him to give the feeling that the Ayrshire landscape enters the building.
The owner is an avid birdwatcher and wildlife enthusiast and welcomed the connection to nature.
The designers left an old barn window ledge in the building untouched, to allow owls to come in and roost at night.
