Puerta del Sol 9, Madrid, Spain

Our work on this building, part of Madrid’s Puerta del Sol streetscape, included a complete refurbishment for a new use. Of particular note was the renovation of the timber structure, using three different types of wood: sawn lumber to replace uprights and wall plates, glulam for joists and floor beams, and LVL for increased cross-sections to bear modified loads. The original interior openings were restored, the metal structure of the premises was reinforced, and new pillars were incorporated, resting on pile caps and micropiles. Brick vaults in basements were also restored and the envelope was fitted with insulation. Facades listed with particular protection were restored with the replacement of joinery. The scope of the project included structural renovation and restoration of interiors in the historic restaurant Casa Labra, so the works were scheduled to suit its needs.
