Edinburgh luxury development scheme to add 14 units A LUXURY development of serviced apartments in the heart of Edinburgh's Old Town is to undergo a £1.5 million expansion. Old Town Chambers, which is operated by Lateral City, is to add a further 14 apartments to its offering. The mix of studio and one-bedroom facilities will be completed in May 2015, less than two years since the scheme was launched. The expansion, by Chris Stewart Group, will take the total number of serviced apartments up to 50, which will sleep up to 200 guests at 100 per cent occupancy. Lateral City boss Julie Grieve said: "To have the largest five-star collection in Edinburgh in the space of two years is testament to the success of the brand."
