Work is set to start on the £200m commercial development project next to Edinburgh’s Haymarket railway station in Scotland, UK.
The four-acre site is being developed by Interserve and Tiger Developments, who have signed an agreement with Network Rail to start preparatory works in December 2013.
Preparatory works on the railway tunnels below the site are expected to be completed within a period of 12 months.
Under the project, a mix of office, hotel and retail space will be built in the Edinburgh city.
The Haymarket has planning approval for 404,000ft² of office accommodation and 60,000ft² of commercial and leisure space, together with a 165-bedroom hotel and a 320-space underground car park.
Interserve said tenants have already signed up for the initial development phase featuring Q Park, Tesco and serviced apartments provider Staycity.
Food chains Prezzo and Pret A Manger are already committed to phase two, together with advanced negotiations with other occupiers for a further 70,000ft² of retail and office space.
Interserve development director David Westwater said the agreement with Network Rail to start work on the site represents a significant milestone for one of Edinburgh’s last remaining gap sites.
"We are looking forward to completing the underground works during 2014, allowing for above-ground construction to start in early 2015," added Westwater.
On-site construction is expected to start in spring 2014, with the first buildings’ phase earmarked for completion in 2016.
The construction project alone will be worth £150m and will be delivered by Interserve’s local construction team, based in Livingston.
