Mosaic Architecture & Design has submitted an application on behalf of property developer Soller Group for planning in principle to erect the second phase of planned office development at Carrick Street.

If approved, the 17-storey office block will be situated behind the 14-storey phase one building for which Soller Group has secured planning permission, with construction due to start on that in the first half of 2022.

A number of commercial buildings and Glasgow City Mission’s headquarters would be cleared as part of the phase two development.

A design document included with the phase two planning application stated: “The proposed new 17-storey office building comprises 13 floors of open plan office space with an upper level roof terrace.

“At ground floor level, there is a generous double-height entrance lobby with break-out spaces, informal meeting areas and co-working stations.”

It added: “This proposed development of this site presents an exciting opportunity to address the increasing demand for Grade A commercial office accommodation within Glasgow city centre.

“Taking cognizance of the recently launched master plan for urban renewal within the ‘Broomielaw Quarter’ area of the city, a new public plaza linking Brown Street and Carrick Street will be introduced.

“This will provide a defined entrance area and route to the building and also contribute to the rising quality of the local streetscape.”

Soller Group said the second phase of Carrick Square, which will include a new public realm linking Brown and Carrick Streets, will comprise 17 column-free floors of around 17,000 sq. ft. each around a central core, with a landscaped plaza to the north, which can accommodate outdoor events and gatherings.

The building will also offer southern aspects and a roof terrace with panoramic views. A double-height entrance foyer will offer break-out and meeting spaces as well as being A rated for Energy Performance. Carrick Square will also strive for market leading scores in carbon efficiency (both during construction and also in operation), NABERS and BREEAM accreditation, Wiredscore and Well ratings.

Nick Treadaway, founder and CEO of Soller Group, said: “Our submission of a planning application for Phase 2 of Carrick Square is a clear statement of our confidence in Glasgow’s unquestionable ability to bounce back from a challenging couple of years.

“This new phase represents another significant investment into the City and its businesses and people and will not only deliver a world-class new office building to Glasgow, but will generate employment not only on site but for the multitude of businesses that together bring large scale developments to life.

“Carrick Square will not only be the next stage in revitalising Glasgow’s business district but it will also support the recovery of the City itself. We hope to be able to start on site in 2023 with the building completed by 2026.”

As part of the project Soller Group has been working closely alongside Glasgow City Mission to explore the possibilities of acquiring a flexible space in an area of the City that is more helpful for its guests.

Soller have been in discussions with Glasgow City Mission for some time regarding its current address. As part of these discussions, Glasgow City Mission has made known some of its criteria for an improved base of operations in the city.

Charles Maasz, chief executive of the charity, said: “Soller have been working closely with us and have been keeping us abreast of developments at every stage. Soller continue to offer all the help possible as we explore options available to us and consider the wider implications of this development and its impact on our services.”

Neil Haining, director of Mosiac Architecture + Design, added: “Phase two of Carrick Square will be a significant and impressive addition to Glasgow’s skyline so our design proposals have ensured that it reflects both the heritage and the future of the Broomielaw. The sheer height of the space will create a new landmark, but as well as proposing a thoughtfully designed exterior, occupier wellbeing has been very much at the forefront of this project. South facing aspects, a roof terrace, landscaped outdoor space, cycle parking and tenant facilities have all been integrated into our designs to ensure the very best working environment for occupiers at this exceptional business space.”
