APPLICATION USING SLATE
WINNER
Twenty Grosvenor Square: Welsh Slate, working with Richardson Roofi ng
Product:
Natural Penrhyn slate from Welsh Slate was
used by the client on Twenty Grosvenor Square
– a luxury residential development in Mayfair,
London.
According to Welsh Slate, natural slate can
withstand the most extreme environmental
and weather conditions, and, combined with its
natural beauty, makes it the material of choice
for a wide range of diverse applications.
Louvre plant screen, acoustic panelling,
steel frame installation, bespoke PPC
dromers (off-site fabrication), PPC cappings/
Mansafe system/stone paving/artifi cial and
living green walls/lead fl ashings and hot melt
waterproofi ng were also used on the project.
Project:
According to Richardson Roofi ng, access to
the site was diffi cult because of the central
London location, as well as interface and
access issues from one terrace to the other.
Twenty Grosvenor Square has been
transformed into 37 private residences. Two
storeys have been added to the building, which
is where three luxury penthouses sit. The
redevelopment required slating to the mansard
roof that wrapped around the building, along
with the design, fabrication and installation of
57 PPC dormers.
Richardson Roofi ng also undertook all of
the fl at roofi ng at the site, which was stone
paving. Extensive green walls are also situated
on the roof. A mansafe system was installed
to access the upper fl oor, together with Davit
base fi xing points for maintenance.

JUDGES’ COMMENTS
“These are luxurious penthouses with roofs that have been done in a luxurious way. The work is part vertical
and part mansard, which is diffi cult to do. This project identifi es a high level of quality, despite being carried
out in a diffi cult working area, and was beautifully delivered.”
