Plans have been lodged to create a new apartment complex on the site of a former Birmingham City Council office block.
Sama Investment Group is behind the scheme to transform 1 Lancaster Circus in the city centre into a new development of two towers, reaching 41 and 48 storeys respectively.
This latest step follows a consultation period over the summer after the plans for the vacant site were first revealed last year.
The 1.3-acre application site sits next to Lancaster Circus island, opposite the old Central Fire Station in the city's Gun Quarter.
The development would contain a mix of 900 apartments and 700 units for students, likely to appeal to those attending Aston and Birmingham City universities which are both a short walk away.

Proposed amenities include a gym, spa, cinema room and ground-floor space for commercial or leisure uses. The project will also have public open space and a pedestrian corridor, subject to winning the backing of city council planning chiefs.
The final plans have seen the addition of a pavilion to part of the site which Sama said would act as a focal point for the development and allow residents and the public to circulate through more effectively.
It will be called 'Perryian Works', a nod to the location's previous home to Perry & Co, the manufacturer of pens, chains and bicycles.
Bilal Ahmed, executive chairman and founder of Solihull-based Sama Investment, said: "Following a period of consultation, we're delighted to submit plans for 1 Lancaster Circus.
"The proposals will transform an underutilised site to deliver a flagship scheme for the local area and city. The proposals will deliver a mixed-use scheme of residential and much-needed student accommodation and support the continued growth of nearby universities.
"Our plans will also help re-establish this location as a destination, offering street-level community uses and green space for residents and the wider community to enjoy alongside a pedestrian corridor that will connect parts of the city to this area.
"We look forward to continuing our progress with the city and our partners to deliver 1 Lancaster Circus in the coming years."
The building, which would be demolished to make way for the two towers, and acquired by Sama Investment the following year.
It was said at the time the decision was prompted by the council moving to more staff working from home, saving the authority around £1.4 million a year in costs to keep the site operational.
Teams in the council's architecture, engineering, building, finance, environmental and consumer services departments were previously based there.
