Ashley Gardens, Westminster, London SW1


IOTA was commissioned by a Residents Group to design and supply a planted perimeter, around a shared 7th floor roof terrace, in Ashley Gardens, London SW1.

IOTA’s perimeter was to be the sole safety perimeter for the completely exposed roof terrace; and IOTA was responsible for all works, save Installation – to include Site Survey, Design, Manufacture and Supply.

IOTA’s design passed Structural Engineer evaluation; and it met the requirements of the City of Westminster Planning Office, in terms of providing a secure edge protection against falls from height from the roof terrace.

Individual elements of the design included:

  • 84 linear m of W 500 x H 1100mm inter-connected steel planters with integrated balustrades
  • Planters shaped to follow the recesses of the roof terrace perimeter
  • 2nr. lockable gates at entry points to roof terrace
  • 8nr. removable ‘sluice gates’, with security locks, to enable maintenance access to drains outboard of the planted perimeter
  • Integration with mansafe system, to enable safe working outboard of the planted perimeter [drain maintenance, window cleaning etc.]

Located within the Westminster Cathedral conservation area, Ashley Gardens is one of Westminster's most sought after mansion buildings. It is exceptionally located close to the open spaces of Green Park and St James's Park; the numerous shops and restaurants at Cardinal Place; and the transport links at both St James's Park and Victoria Stations. The 7th floor roof terrace affords stunning views of Westminster Cathedral and its piazza, as well as of the neighbouring districts of London.
