The announcement follows SGI’s acquisition of the property from a client of OakNorth Bank in March 2025 and coincides with the submission of a building warrant to the City of Edinburgh Council.

The project team brings together a strong blend of national capability and regional experience. AHR is leading the architectural design, drawing on a proven track record in retrofit and commercial workplace projects, while Buro Happold is providing structural and M&E engineering consultancy to ensure the building systems meet modern performance standards. Gardiner & Theobald is acting as quantity surveyor and employer’s agent, overseeing cost and programme management, with Muir Construction appointed as main contractor. Property management will be delivered by Redpath Bruce following completion.

The project will see the vacant 89,863 sq ft office building upgraded to meet the needs of modern occupiers, with works expected to begin on site in summer 2025 and the refurbished space available from spring 2026. Originally constructed in 1999 for the NatWest Group, the six-storey building occupies a prominent site in one of West Edinburgh’s most established business locations. With a shortage of high-quality, out-of-town workspace in the city, SGI’s plans focus on improving environmental performance and providing adaptable space to suit a wide range of occupiers.

Key interventions will include upgrading the building’s mechanical and electrical systems to target an EPC A rating, alongside measures to improve energy efficiency and long-term sustainability. The existing atrium spaces will be enclosed to increase net lettable area and allow for greater sub-division, enabling the building to accommodate a range of requirements – from microbusinesses through to larger corporate occupiers.

Paul Kelly, managing director at Scarborough Group International, said: “This is a well-located building with solid fundamentals that just needs the right investment to make it fit-for-purpose in today’s market. By focusing on energy performance, flexibility and functionality, we’re confident the former Younger Building will meet the needs of today’s occupiers. Assembling a strong, delivery-focused team is a key part of that process, and we’re pleased to now be progressing with our plans.”

Gurminder Sanghera, director at AHR, added: “This project is a fantastic opportunity to transform a large open-plan office into a vibrant, future-ready workplace. By reimagining the space, we will create a more flexible and sustainable environment that delivers a much wider range of business requirements. With rising demand for high-quality, energy-efficient workplaces that enhance peoples’ health and wellbeing, our design approach focuses on human centric design principles to unlock the building’s full potential— to create attractive workplaces with amenities where people can thrive.”
