Liverpool City Council has approved two private residential and two student accommodation schemes totalling 1,000 bedrooms at its latest planning committee.
The developments were designed for four different clients by architect Falconer Chester Hall.
The successful proposals include a residential scheme for a vacant cleared site at Simpson Street for Baltic Developments, which will provide 156 residential studios as well as 12 ground-floor managed office units and three meeting rooms.
An application for developer Jam Works to bring back into use floors two to eight of 11-17 Parker Street in the city centre was approved.
This will see the creation of 72 micro-apartments and 19 studios, plus the addition of a two-storey rooftop extension. The upper floors have been vacant since the 1980s.
A 352-bed student property on vacant land at Chatham Place, Overbury Street and Queensland Street for developer System was given the co-ahead. The U-shaped block would be divided into eight studio apartments and 63 cluster units with their own communal lounge and kitchen.
FCH produced a scheme for almost 400 bedrooms for Gipsy International on the derelict site of the former Imperial Student Halls of Residence at the junction of Byrom Street and Great Crosshall Street.
These will be delivered in a 12 and 14-storey building arranged in 68 clusters and 56 studios, with a ground floor commercial unit and student services.
Adam Hall, managing director of FCH, said: "Usually we are representing one, or occasionally two clients, on these occasions, but to have four projects up for planning is extremely rare.
"The practice has been incredibly busy with work here in Liverpool."
