SIKA SARNAFIL CHOSEN FOR WALKIE TALKIE’S CURVED WALKWAYS
2 March 2015 – London’s distinctive Walkie Talkie building is 160m (525ft) tall. Designed by architect Rafael Viñoly and costing over £200 million, 20 Fenchurch Street is a 34-storey commercial skyscraper in London, now ubiquitously known as the ‘Walkie Talkie’ building due to its top-heavy form. A large viewing deck, bar, restaurants and Sky Garden are included on the top three floors.
Awarded the project in February 2014, Cambridge-based contractor Fenland Flat Roofing was required to provide a lightweight walkable roof area for the access walkways and perimeter edges of the glazed roof to the garden and restaurant. The roofing product had to be carefully selected as it needed to curve in two directions due to the unique design of the building.
Sarnafil G410-12EL single ply provided the solution to this design criteria, thanks to its excellent flexibility and weldabilty, while offering outstanding resistance to weathering, including permanent UV irradiation. This was installed in Lead Grey to the BMU Track and covered with SarnaTred walkway tiles, allowing durable and slip resistant access for maintenance workers – a vital safety consideration.
The second part of the project was to provide a flexible high performance waterproofing membrane to the bespoke ‘Shoulder’ areas in white, to match in with the steelwork structure colour, using Sarnafil G410-15EL Traffic White.
The Walkie Talkie project stands out due to its sheer size and height, creating challenging access issues. As there was no scaffold available, the Fenland team had to work off harnesses and safety lines on a leading edge and had to traverse the glass roof of the building to access the work area. All tools and equipment had to be properly secured at all times. To maintain the most stringent health and safety standards required diligence and planning, rewarding workers with stunning views across London.
High skill levels were required to overcome the various tricky details on the roof and the team had to interface with multiple trades. Fenland completed the project in August 2014 on time and to budget.
Internally the Walkie-Talkie provides a mixture of 13,000sqft of retail space and 680,000sqft of top quality offices with panoramic views of London. It is designed to have a BREEAM excellence rating.

Walkie Scorchie Building
20 Fenchurch Street Building
The heat-ray effect of the City’s Walkie-Talkie skyscraper which melted parts of cars in the City last summer will soon be fixed, the developers of the building said today, reports the London Evening Standard.
The curved surface of the £500m building, being developed by Land Securities and Canary Wharf Group, created a ‘solar glare’ effect which focused sunlight and warped the panels of a Jaguar, melting the wing mirrors and badge. The nickname Walkie Scorchie is proving popular!
To fix the problem ‘sun shades’ will be fitted to the building under a “brise soleil” system, costing in the “low single digit millions” according to the firm. Planning permission has been granted for the solution and work will begin by the end of May, lasting around six months. The solution has been designed by the original architect Rafael Vinoly along with solar glare experts Loisos + Ubbelohde.

A superb set of images of a building that is really difficult to capture. No doubt once the roof garden is completed a lot of attention will focus on it – well it is futuristic and unique for the capital – but the key views for most Londoners will be the ones Nick has used. The lines are smooth and beguiling but unlike most of the skyscrapers in the City the plan is square, which makes the basis for the tower a little dull. Hence the device of expanding the form outwards as it rises, creating interest.
New photos of 20 Fenchurch St Building as construction of this controversial skyscraper nears the top. The 37-storey tower that breaks with the perceived boundaries of common architectural expression and is located away from the main cluster of skyscapers in the City of London.
The building billows out towards the top, the opposite of a typical skyscraper design which aims to get more slender as it rises.

Once the roof garden is in place it will no doubt improve this building’s appearance, adding interest and lightness to partially offset the building’s huge mass, but only partially – this building is too bulky and goes against all that one learns as an architect and what one feels instinctively as a designer.
