VBS delivers balcony excellence in London.

Glass Balustrades in LondonClear glass balconies are a striking architectural design feature of the landmark Baltimore Wharf development in London’s docklands. Kathy Wilkinson explains for Balcony Views how Viking Balcony Systems Ltd developed a custom-built balcony solution, realising the architect’s original vision for this expansive project that will transform the area’s skyline ahead of the 2012 Olympics.

Breathing new life into the former London Arena site, Baltimore Wharf is an exciting and ambitious £150 million mixed development comprising private and affordable housing, retail, leisure and community facilities. Designed by architects Skidmore, Owings and Merrill Inc, it is among several significant construction projects in the Docklands area being undertaken by international construction firm, Ballymore Group.

Construction started three years ago on the 6.8-acre former entertainment site, which is across the water from Ballymore’s recently-completed 50-storey, neon-lit Pan Peninsula residential development. Phase One of the Baltimore Wharf development, which includes more than 600 apartments in five separate residential blocks, is due for completion at the end of 2009.

Glass Balconies in London

As a key architectural feature of the buildings’ external facades, the design and installation of the external balconies required a particularly considered – and inventive – approach. Working closely with the architect and developer, commercial balustrading specialists Viking Balcony Systems Ltd (VBS) developed the bespoke 21st century balcony solution to suit the exacting requirements of the multi-storey buildings and, just as importantly, the £3 million budget.

The result is a ‘one-stop’ balcony system solution including frame cladding, decking and balustrade, delivered flatpacked, complete and ready to install.

VBS was chosen for its ability to offer a complete design, supply and install balustrading package using a no-maintenance glass and aluminium system.

This offers a competitively priced and aesthetic alternative to structural glazing. Instead of posts and structural glass, the aluminium hand-railings take the load to provide all the required strength and support and meet all the relevant building regulations. Utilising the handrail allows the balustrade to span certain lengths without the need for vertical posts. Once these are exceeded, vertical posts must be introduced.

Because the Balcony system takes the load at the handrail, rather than the base, up to 3.8-metre widths of straight glass balustrading can be achieved without the need for vertical posts.

A new aluminium handrail, finished in Royal Chrome to look like shiny stainless steel, and lower track extrusion were specifically designed for the Baltimore Wharf apartments. This allows for relatively simple fitting to the main steelwork. Handrails are fitted to window mullions using a special single stage cladding that clips on to the speciallydesigned lower track.

Feature fascia

“Clear structural glass was originally specified. However our solution using 4mm + 4mm laminated glass to retain a clear view, without the need for posts and at a very competitive price satisfied the key requirements for this prestigious project,” explains Grainger.

“What is new about the system is that it is the first time VBS has provided a flush-fitting anodised extruded aluminium feature fascia which provides a detail to match the main buildings’ window frames. This hides the steel balcony supports to present a neat front face to the structure.”

This was achieved through close collaboration with the architect and developer from the early planning stages to meet the challenges of making the design work with no posts and to keep the structure down to a minimum. Measuring 3.0 metres x 2.0 metres and 2.3 metres x 2.0 metres, the balconies did not require any posts as they were within the ‘no post limits’. Because the VBS system takes the load at the handrail, rather than the base, up to 3.8-metre widths of straight glass balustrading can be achieved without the need for vertical posts.

An added advantage of the system – particularly for high-rise buildings – is that panel replacement, if needed, can be done quickly and safely from inside. Panels are supplied up to 1.2 metres in length for ease of transportation and installation.

The result is a distinctive balcony and a well-engineered product. We are very pleased with how VBS has executed the entire concept, from the initial planning to the final installation. It’s a very tidy and contemporary effect.”

As well as supplying 377 balconies for the project, VBS also solved the logistical difficulties of moving them through the buildings. The team spent over six months developing a flat-pack balcony that could be lifted into place and installed in the shortest time possible.

packed balconyFlat packing is the answer to moving goods through a multi-storey building, as Grainger explains, “The flat-pack concept works extremely well, just like the furniture you buy from a certain Swedish retailer! There’s no transit damage as all the items are securely protected. Installation is also much simpler and quicker as all the components are together on site before the balcony is craned into place.”

Although it will be some time before residents can make full use of the extra outdoor space and clear views provided by the glass balconies, their impact is not lost on Ballymore Group’s Building Envelope Manager, Mark Jackson, who comments, “Balconies are a desirable addition to apartments as they create an extra, practical living space where occupants can sit outside and relax. The clean lines of the aluminium hand railing and glass panels create sharp-looking balconies that really enhance the external façades.

“The VBS bolt-on concept has also worked really well for us and made installation a much simpler and faster process. Having all the materials in place to complete the balcony once it is in place definitely makes life easier. Having one supplier for the entire balcony package also brings a number of advantages in terms of overseeing the entire installation, keeping to the client’s schedule and the budget on track.”

In conclusion, Grainger says, “This new system represents an important breakthrough and one which can readily be applied to future commercial and residential projects, whatever their size. It shows that VBS can adapt the system and provide additional features to it, which greatly enhance the design of balconies. The design is very contemporary and adds to the aesthetics of these modern buildings by providing visual simplicity to the architecture.”

Whether made of stone, wood or cast iron and now glass, the balcony is an enduring and popular building feature that has been with us for centuries. Design has continued to evolve to meet the changing face of architecture. The Baltimore Wharf project represents another step forward in the evolution of balcony design, taking it firmly into the 21st century.
