The hotel, run by the Clermont Hotel Group and built in 1973 by J Lyons & Co, sits on the bank of the River Thames near Tower Bridge.
Existing maintenance areas are due to be turned into a new Class E(b) restaurant unit, according to a fresh planning application sent to Tower Hamlets Council.
This renovation, estimated to cost up to £2 million, comes more than a decade after a similar plan was greenlit in August 2014 but later shelved.
The new proposal is for the ground-floor workshop and storage space, which is now empty, with maintenance housed elsewhere in the hotel.
The 222-square metre area was previously filled with workbenches, office space, and stores but has been idle for some time.
The new restaurant will sit alongside an existing Costa Coffee unit, both operated by the hotel.
Inside, the eatery will include an entrance, a seating area for about 50 guests, an order area, and an open collection point.
At the back, there will be a kitchen, preparation and storage spaces, and bathrooms, including an accessible toilet with baby change and three unisex cubicles.
The restaurant layout is aimed at offering flexibility, with a different mix of fixed booths and loose seating.
The plans indicate ten new full-time and ten part-time staff.
According to the planning statement, the unit will be serviced through the existing hotel, using back-of-house corridors.
Deliveries and waste removal will be carried out via the existing hotel loading bay, with recyclable waste handled and sorted alongside hotel waste.
Major adjustments to the mezzanine level plant deck above the new restaurant are also on the cards.
Currently housing numerous air-conditioning condenser units serving the hotel and Costa Coffee, the deck will remain but will see some changes in location for the units.
Due to the mass and construction of the building, it is not possible to take the kitchen’s extraction system to roof level.
Instead, it’s proposed that the new kitchen extract fan, complete with noise reduction and a combination of odour control filters and treatments, be installed on the mezzanine level.
External changes will include replacing the existing blockwork walls and high-level glazing with aluminium framed shopfront glazing in blue, matching elements of Tower Bridge.
The new louvred panels for the kitchen will offer both visual and sound reduction.
Further changes will see the existing steps modified to suit the raised floor level, providing level access for wheelchairs.
On top of that, the current fair-faced blockwork infill walls and high-level glazing are set to be replaced with aluminium framed shopfront glazing and high-level feature louvres.
Existing metal faced doors and windows will also be replaced.
A new glazed entrance door and screen is planned for the west elevation of the building, with new fire escape doors for the north side.
New metal cladding in red is also set to be installed to the existing horizontal fascia between ground and mezzanine level.
A new face for the creation includes new fascia signs and a projecting sign to be introduced, showing signs on elevations and visuals, with the final designs to be developed to suit the restaurant branding.
The planning application reference for the new dining unit is PP-14596630.
If approved, the building work is due to start in April 2026, and is expected to last three months, finishing in July.
