Canongate Block 2, Royal Mile

Redpath was commissioned to deliver conservation and energy efficiency works to this post war category B listed building.

As part of this ambitious pilot project for Edinburgh World Heritage, Redpath was commissioned to deliver sensitive and appropriate conservation and energy efficiency works to this post war category B listed building. Designed by Basil Spence & Partners in 1969, this building is located in the Edinburgh Old Town Conversation Area and UNESCO World Heritage Site.

Canongate Block 2 is a complex configuration with 12 ownership properties. There are two commercial units on the ground floor that continued to operate uninterrupted throughout the works.

Whilst supporting Edinburgh’s goal to become a net zero emissions city by 2030 and contributing to the Scottish Government’s ambitious plans to meet climate change targets by 2045, this project has also improved specific issues with the property due to the nature of its age and construction, notably poor ventilation and indoor air quality. The outcome of this project has been:

  • An energy efficient building resulting in an anticipated drop of 28 tons of carbon emissions per year, the equivalent to planting almost 3,000 trees.
  • Improved health and wellbeing of residents
  • long-term issues with mould and dampness solved
  • Conserving a listed building within the World Heritage Site
  • Compliance with the 2032 Scottish Government energy efficiency regulations (for the residential properties).


We have delivered:

  • Window and door replacement. Reinstating the original window scheme, including balcony windows, to Sir Basil Spence’s original specifications, enhancing the architectural integrity of the building.
  • Cavity fill insulation
  • Mechanical & Electrical renewal
  • MVHR installation and associated internal redecoration
  • Render repairs and painting. Paint colour was matched to existing as determined by the Scottish Lime Centre analysis. Keim Masonry Paint was used reinstate the original colour scheme determined by archive images and Edinburgh University research.
  • Felt roof encapsulation
  • Concrete repair and cleaning.
