The developer has lodged an application for One Brunswick, a U-shaped residential development on the site of the infilled Toxteth Dock.
The 2.4-acre site is located immediately south of Brunswick Dock in Liverpool and is currently used as a surface car park.
Carpenter Investments proposes creating a 478-apartment development rising from four to 16-storeys.
L7 Architects, Carpenter’s in-house design, has drawn up the plans.
The scheme is described by consultant the Planning Studio as “a game-changing piece of architecture that truly brings the concept of placemaking to life”.
The most eye-catching element of the project, which comprises one-, two- and three-bedroom apartments, is a 50,000 sq ft landscaped green roof trial that meanders around the curved form of the building.
In addition, the project features 10,000 sq ft of office space, and 11,000 sq ft of additional commercial space, including a rooftop restaurant.
Elsewhere off Brunswick Way developer Maro won consent for a 552-apartment project last December. Carpenter’s scheme is also close to Herculaeum Quay, a project that was beset by delays and controversy before eventually being completed last year by a consortium of investors.
