The area surrounding Heygate a residential
housing estate from the 1970s located in the
Eiephant and Castle quarter in London is
noted for its bad reputation. Its mighty
apartment blocks made of concrete with
deck access and social housing apartments
became m ere and more desoiate. The com-
munity impacted by poverty and crime
struggles with some of the worst sociai
probiems in the city. R evitalisation was ur-
gently necessary. With 1.5 million Pounds of
funding
Heygate will be replaced by a new
urban community centre within the next 15
years
compiete with green spaces retail
and most cf
ail
social housing. Rcughly
5000 units are planned. For this purpose a
competition was intended tc provide ideas
for social housing construction for 15 loca-
tions.
One of these ideas was realised along
Brandon Street. The facade its coiours
changing from yellow to dark red and
curved tc accomm odate four trees is highiy
visibie frcm afar. After a iong search the ar-
chitects discovered the hand-colcured ce-
ramic tile used in this project in France. Its
price is ccmparable tc weed clad ding. A re-
inforced concrete frame serves as structurai
system en the ground level whiie the upper
floors feature lightweight steel ccnstructicn.
The high degree of prfabrication and the
resulting limited amount cf time required for
instaiiaticn en site and crane service re-
duced ccnstructicn time and costs. Detaiied
planning and ccordinaticn cf dimensicns cf
the individual coffered elements and the
biack and w hite benches that fciicw the
facade curve led tc further savings. They
consist cf oniy three different elements -
convex straight and ccncave - and de-
lineate a smail public space. Sustainabiiity
was an important aspect as
weil:
U values
cf facades range frcm 0.11 to 0.19 W/m^.
Heat recovery and grey water and rainwater
re-cycling are aIsc included. Apartments
are equipped with light-coloured ficcrs and
