The former Donaldson’s
school and the new
terrace are set back
behind a large lawn
members as the entire parabolic curve of the
terrace is formed with facetted steelwork.
“The required car park spacings dictated
the grid pattern,” explains Hadley Haddow
Project Engineer Russell Henderson.
“Once we’d designed the basement
we then carried this pattern up
through the first three levels of
apartments, and so avoided the
need for transfer structures.”
The only exception to this regimented
steel grid pattern is the second and third
floors. To accommodate the mezzanine
levels within the second floor, a number of
off-grid columns have been inserted and
these are supported by transfer beams at
first floor ceiling level.
The other exception is the penthouse
floor which, as well as being set back, also
accommodates much larger apartments –
roughly one flat occupying the area of two
This floor is set out on an entirely
different grid pattern and so a series of large
transfer beams support this level’s columns.
Most of the inner curve of the terrace
will be fully glazed, giving residents plenty
of natural light and views of the college
building and beyond. The outer arc will
feature a natural stone cladding. Above, the
terrace will be topped with a steel-framed
roof spanned with metal decking.
The entire Donaldson’s scheme is
expected to be complete by 2020.
