High-level Programme Proposals


Following engagement with residents and the Resident Liaison Groups, the project team is progressing with a combined package approach, aiming to complete all works across the Golden Lane Estate within approximately ten years from the start of the project in 2025.

The programme for each block is set out below. 

The Investment Programme

Indicative Timeline 2025–2035

This approach is based upon the following assumptions:

  1. All blocks on the Golden Lane Estate will require decanting (apart from Stanley Cohen) to accommodate window refurbishment

  2. City of London Corporation can accommodate decanting of 2 blocks at a time using separate contracts and different principal contractors

  3. Decanting is based upon a rolling programme of 6 flats/maisonettes at a time for a period of 6-8 weeks

  4. Works will be delivered as part of competitively tendered packages consisting either of a single block or groups of blocks as indicated below

Key:

  • Package 1: Roof covering replacement, fire safety and electrical works (does not require decant)

  • Package 2: Window refurbishment, ventilation, communal decorations and external fabric repairs (requires decant)

  • Package 3: Packages 1 & 2 combined (requires decant and till take longer as a result)

  • Package 4: Fire safety (including sprinklers and compartmentation), window refurbishment, ventilation, electrical works and internal communal decorations (potential decant, severe disruption expected as minimum).
