The 55-year-old office tower is to be substantially demolished and rebuilt to modern standards.
Only the foundations and core of the original building will be retained.
British Land initially considered a deep refurbishment of the building but decided that the structural elements and facades were not adaptable to today鈥檚 requirements.
Instead it has opted for deconstruction but is planning to reuse 31% of original structure, including all the steel and aluminium and up to 81% of the glass. It is also harvesting, testing and reusing concrete slabs.
The redesigned 31-storey building will provide 8,000 sq ft of office space at Regent鈥檚 Place as well 4,000 sq ft of restaurant and caf茅 space, with terraces overlooking remodelled public realm.
Euston Tower will be all-electric, both during construction and in its operation.

The design is being led by Danish architects 3XN, supported by Adamson. Structural engineer and building services consultant is Arup.
Completion is expected at the end of 2030.
Mace Construct managing director Ged Simmonds said: 鈥淭his world-class science and technology building with new offices and lab-enabled workspaces will exemplify our expertise in delivering retrofit developments of this scale. By incorporating sustainable practices and cutting-edge engineering, we are not only showcasing the potential for forward thinking office redevelopments, but also highlighting how reuse strategies can drive circularity in construction.
鈥淭ogether with British Land, we are setting a precedent for how buildings can be repurposed to meet modern demands while reducing their carbon footprint."
British Land head of development David Lockyer said: 鈥淔ollowing planning approval last week, we are pleased to be working with Mace to deliver this incredible scheme 鈥 the first West End tower in a generation, and likely to be the last.鈥
