Greenwich Peninsula is a vast and unique development by Knight Dragon to regenerate 150 acres of historically industrial land. The entire development provides 15,000 homes, 13,000 jobs and 48 acres of public green space.

Flanked on two sides by the Thames the central location provides residents with easy access to all the capital has to offer and the serenity of a river-side home.

Sapphire also provided Glide-On™ balconies for blocks, M103, M114/115 and M117.


The design of the building featured a column requiring the balconies to be designed and installed around it.

The project also used system scaffolding which, while quick to set up, are limited by set heights. This was a challenge because the height of the scaffold conflicted with the placement of the stubs making the installation of the arms difficult.

The central London location, on Greenwich Peninsula, made navigating the capital with lorry loads of balconies challenging and space for storage limited.


The fascia design and the inclusion of the columns meant the design team needed to find a suitable solution to maintain ease of install on site. The team designed the balconies to slide on to the support arms seamlessly incorporating the column in the design. Glide-On™ balconies bring the benefit of greater tolerances making the challenging install smooth and efficient.

The system scaffolding may have been a significant challenge for traditional balcony methods and may have added time to the project programme. To overcome the placement of the scaffold conflicting with the stubs we installed the arms quickly as the scaffold was struck down the building. The installation of the arms was carefully coordinated with other trades to avoid conflicting with other works. Once the arms were installed the balconies simply Glide-On™ for a quick and easy installation.

The limited space both logistically and on site was overcome by carefully coordinated deliveries in keeping with the needs on site. Our logistics team worked with the site team to ensure the balconies arrived as needed and could be quickly unloaded and installed with minimal disruption on site and to the local area.

Installation Process

Step 1: Schoeck cast in anchors were cast into the slab.

Step 2: Cassette® balconies were preassembled offsite, including the balustrades, decking & soffits.

Step 3: Cassette® balconies were transported with balconies ‘nested’ onto each pallet making transport both cost effective & safe. Balconies were pre-slung offsite ready for installation upon arrival.

Step 4: Once lifted into position, the Cassettes® simply Glide-On™ to the pre-erected support arms, before completing the simple mechanical fixings.
