Tower Hamlets Council has approved plans for a new 54‑storey residential tower at 77 Marsh Wall on the Isle of Dogs, a major redevelopment that will replace an existing 17‑storey office building opposite South Quay DLR.
The scheme, brought forward by Areli Developments in partnership with British Airways Pension Trustees and designed by Patel Taylor, will deliver a mix of housing types and short‑stay accommodation within a single tower that will rise to about 190 metres — making it Canary Wharf’s third‑tallest building.
What the development will contain
The approved proposals include a total of 554 homes alongside 266 serviced apartment (aparthotel) rooms. The homes are split between different tenures and living models, reflecting a trend for mixed offerings in large central London schemes:
- 195 build‑to‑rent (BTR) flats;
- 238 co‑living homes with shared communal facilities;
- 96 social rent homes;
- 25 intermediate rent homes.
Residents will be offered a range of shared amenities, including co‑working spaces, a cinema, gym, swimming pool, communal kitchens and lounges, plus landscaped terraces on the podium levels.
“We’re extremely pleased to have secured consent for 77 Marsh Wall,”
The scheme also provides publicly accessible areas: more than 3,100 sq metres of open space within a three‑storey podium, including new gardens, about 200 sq metres of community floorspace and roughly 430 sq metres of retail provision at ground level.
Jobs and construction
Areli has estimated that the build programme will support around 2,200 construction jobs each year during its delivery, and that once complete the project will sustain approximately 151 full‑time equivalent operational jobs. Planning documents show the existing office block, constructed in the early 1990s, will be demolished to make way for the taller mixed‑use building.
| Item | Number |
|---|---|
| Total new homes | 554 |
| Serviced apartment rooms | 266 |
| Public open space | 3,100+ sq m |
Local context and implications
The Isle of Dogs and Canary Wharf have seen a wave of redevelopment over recent years, shifting some office floorspace to residential and leisure uses. This project adds a new model to the area by combining traditional BTR flats, co‑living units with shared facilities and short‑stay serviced apartments in the same tower — a blend the developer describes as one of the largest integrated, multi‑tenure residential schemes in the UK.
For nearby residents and commuters, the scheme will change the skyline and increase local footfall, especially around South Quay DLR. The planning consent includes provisions for public amenities on the podium and retail at street level, intended to activate the riverside frontage and provide community benefits.
Tower Hamlets officials approved the plans following submission in October 2025. The next steps will involve detailed design work, contractual arrangements for construction and the usual pre‑start conditions set by the council. Timescales for delivery have not been published in the council decision notice.
Given the scale of the development and its location on a prominent Docklands site, it will be subject to scrutiny as construction progresses, both for its impact on local services and for how the different tenures operate side by side once occupied.
