Lamb's House is a Grade A, 17th century former merchant's house in Leith. It is one of Leith's oldest and finest buildings. The property had been used in recent years as a day care centre and as offices for the National Trust for Scotland. In 2009 it was purchased by Groves Raines Architects with the intention of carrrying out a sympathetic restoration and extension of the building.
The restoration included replacing all internal floor boards and sarking boards, removing internal partitions that had been added over the years, reinstating and restoring fireplaces, forming a new timber balcony, replacing shutters and replacing the lime render to the external elevations. The extensions included a new three-storey office pavilion and a similar residential pavilion.
The redevelopment also included the re-creation of Water's Close, which had been somewhat lost in a previous development of the area.
