The carriage house interior was fully rehabilitated with the original wood beams and brick walls exposed where feasible.  The garage was meticulously documented locating every stone and joint width, and disassembled to shore up and rebuild the hillside retaining wall. New stone was mixed with original stone units that could be re-used to ensure visual continuity and recreate the random pattern of the stone walling.  

Because of the extensive geo-technical reconstruction that required internal buttressing, the usable space would have been considerably reduced. Because the property fronts a mapped street, and other properties had been modified or originally built to the edge of the raod, a waiver was sought from the Board of Standards & Appeals (BSA) to enlarge the building 7'-0" towards the road to compensate for the lost square footage. The length of the house was also extended by 4'-0" reducing the width of the stepped walkway.   

The BSA agreed that the enlargement was no less compliant than the original construction.
