A historic Edinburgh home designed by Sir Basil Spence has been given a contemporary new extension.

David Blaikie Architects has completed the remodelling and extension of Glenwood, a Category B-listed property in Craiglockhart and the first-ever commission of architects William Kininmonth and Sir Basil Spence.

The pair formed the partnership Kininmonth and Spence in the early 1930s, with Sir Basil Spence later gaining international recognition for major works including Coventry Cathedral and his contribution to the 1951 Festival of Britain.

Originally designed in 1931, the house is considered a significant piece of Scotland’s architectural history.

The Edinburgh-based practice was tasked with updating the north-range of the property’s former service accommodation, replacing it with a modern open-plan living and dining space that connects directly to the private rear garden.

The redesign draws on a contrast at the heart of 20th century British architecture.

While Glenwood was originally designed in an Arts and Crafts style, Kininmonth and Spence were also working on the more radical, Bauhaus-inspired Lismhor elsewhere in the city.

David Blaikie Architects said this contrast became the inspiration for the new addition.

The extension features a sweeping zinc-clad curved roof over largely glazed walls, designed as a contemporary contrast to the straight lines of the original house.

Low eaves draw the eye towards the garden, while a timber-clad circular drum anchors the structure and forms the centre point of the internal layout.

A south-facing clerestory glazing band has also been introduced to maximise natural light and warmth in the otherwise north facing space.



David Blaikie, director of the practice, said: “By introducing the modernist theme of playing a curve against the straight lines of the original house, we are making a clear distinction between old and new in a considered and deliberate act.

“Materials pay respect to the original house, but the construction is resolutely 21st century in its use of technologically advanced building systems.

“We hope that the contextual respect, sculptural forms, solar design, and exceptional workmanship would have excited Kininmonth and Spence if they could see it today.”

Glenwood has had only two owners since it was first built.

The project reimagines one of Edinburgh’s most historically significant homes for modern living while preserving its architectural legacy.
