Guastavino, Rafael, Sr., Estate
Also known as: Rhododendron
Why it's listed
Rhododendron, the Blue Ridge estate of Spanish-born engineer Rafael Guastavino, Sr., sits on about eight acres of grounds now held by Christmount Christian Assembly near Black Mountain in Buncombe County, North Carolina. Guastavino occupied the property from 1895 until his death in 1908. The main house was later razed, but its terraced foundations, a vaulted wine cellar cut into the hillside, a fieldstone retaining wall, and earthworks including two stone-edged ponds and a terrace remain. The most important survival is a beehive kiln ruin and its intact 60-foot brick chimney, used to make the ceramic tiles for Guastavino's patented cohesive construction method, which used thin tile layers in vaults. The site is regarded as significant for its link to his building technology, for his residence there during his most productive years, and for its designed landscape of holly, hemlock and earthworks typical of private estates in the region.
Significance in brief: The estate is regarded as significant for surviving ruins of Guastavino's tile kiln and its brick chimney, linked to his "cohesive construction" system using thin tile membranes. It was his principal residence during the last 14 years of his life, the period of his greatest professional productivity. The designed landscape of earthworks, ponds and plantings is also cited as an example of private estate design in Western North Carolina during the turn-of-the-century building boom.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
