In what is being called the largest letting in Scotland since the EU referendum, the management, engineering and development consultancy Mott MacDonald has agreed terms to move into Abstract Securities’ St Vincent Plaza office scheme in Glasgow.

Mott MacDonald will relocate its office from 1 Atlantic Quay in mid-2017 and will take the entire fifth and sixth floors of the development comprising 34,515 sq ft on a new 15 year lease from February 2017.

St Vincent Plaza is a speculative Grade A office development of 172,280 sq ft in Glasgow city centre.

Abstract CEO Mark Glatman said: “We are delighted to welcome Mott MacDonald to St Vincent Plaza.

“They join KPMG, Whyte and Mackay and the Registers of Scotland to add to an impressive list of occupiers in the building who see the fantastic quality of space we offer at such a competitive value.”

Mott MacDonald’s Andrew Oldfield said: “We have been based in Glasgow for over 70 years and have been involved in some of the city’s most recognised infrastructure, including the Clyde Tunnel, Prestwick Airport and Strathclyde Light Rail.

“We also supported the successful delivery of the Glasgow Commonwealth Games in 2014.

“With almost 400 employees in the city we’re involved in projects across a diverse range of sectors including environment, power, water and transport, as well as buildings and infrastructure, working with clients such as Transport Scotland, Glasgow City Council and Scottish Water.

“Moving to St Vincent Plaza will provide a modern working environment for our staff and support our growth for years to come.”
