Exterior, Stone Siding Material, House Building Type, Gable RoofLine, and Shingles Roof Material The White House was originally built in the mid-1700s on the Isle of Coll, but was subsequently abandoned for over 150 years. With only ruins remaining, the owners enlisted WT Architecture to complete a renovation that would incorporate what was left of the former structure with a modern and low-impact home. The result is a stunning mix of the original stone façade with new large windows that frame the ocean view.  Photo 4 of 11 in Merging Old and New With These 10 Modern Renovations in Scotland
