Sapphire balconies complement Deptford Foundry’s premium apartments

Sapphire balconies complement Deptford Foundry’s premium apartments

Deptford Foundry is located in a historic area of south-east London and sits on a former metal foundry dating back to 1831. Once a thriving centre of exceptional design, the area is now home to premium apartments each benefitting from access to private Sapphire balconies and terraces.

The area’s rich industrial heritage is reflected in the design of the balconies featuring tie wires and bronze Cassettes® and soffits.


The development is located tightly between two railway lines, limiting room for site equipment and adding an element of complexity to the install. Due to safety concerns the site team could not go over the boundary over the railway line leaving minimal space for cranes to manoeuvre the balconies into place.


The proximity of the railway lines meant that traditional balcony designs would have been hazardous to install as nothing could hang over the boundary in the process. Sapphire’s Glide-On™ solution overcame these concerns as the modular prefinished design arrived to site complete and ready for install. The project manager commented that the offsite manufacture of the Sapphire balconies was “invaluable to this site because of the issues of site logistics”.

The simplicity of the install process meant the balconies could Glide-On™ to the awaiting arms and secured in place without the need for installers working below a live load. Installers remained inside the apartments behind Sapphire’s internal door guards preventing any risk of the leading edge. Once the balconies were on the arms they could be safely bolted in place and the final boards of decking could be fixed in place.

The project manager commented, “balconies were installed straight from the lorries” and that the system was “fantastically simple”.

Sapphire’s logistics team worked with the site team to ensure the balconies arrived when they were needed and when the site was ready for install. The site team reported a fast install limited only by the façade progress and the needs of other trades on site.

Step 1 - Cast in anchors were cast into the slab & incorporated thermal break connections offering superior rigidity to the balconies.

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.
