Comprising a mix of studios and one bedrooms, the luxury apartments will be completed in May 2015, less than two years since Old Town Chambers was launched.
The expansion, at a cost of £1.5 million by the award-winning Chris Stewart Group, will take the total number of luxury serviced apartments up to 50, which will sleep up to 200 guests at 100% occupancy.
The apartments, set in the capital’s historic Old Town, will contain double smoked French oak wooden flooring and Italian tiling, alongside the latest home entertainment system and a 24 hour concierge service, making it one of the most exclusive places to stay in Scotland.
Julie Grieve, CEO of Lateral City, said: “We’re delighted to be expanding in such a short space of time. To have the largest five-star collection in Edinburgh in the space of two years is testament to the success of the brand.
“Our occupancy level remains consistently high throughout the year with it reaching 100% throughout key events, such as Hogmanay, rugby Internationals and Six Nations and the Edinburgh Marathon. The demand from our visitors has spurred us to expand.
“In addition, the location itself is second to none. Being right in the heart of the historic Old Town with views over Princes Street, coupled with state-of-the-art facilities, makes it a very special place to stay in the city.”
The Old Town Chambers currently contains 36 apartments comprising of studio, one, two and three bedrooms, as well as three stunning penthouses and a 15th century townhouse.
Unique features include original period wall paintings, exposed brick, through to bluetooth Bose sound systems, Smart TVs and a multi-zone heating system in every room. Entry is via a keypad for which every guest has a specific code. Prices range from £99 to £1200 per night.
