W. Ellen Street, Chicago IL.
This
project is a prime example of how thorough understanding and
management of the governing ordinances and codes can transform a
seemingly useless lot into a profitable enterprise for the developer
and an asset to the neighborhood. The lot for this two unit
condominium development is a small trapezoid of 1802 sq. ft and is
bounded on one side by Ellen Street and on two others by an alley. The
biggest obstacle to development related to the rear lot line. The
required rear yard is determined from the lot line most parallel to
the front lot line, which in this case was the rear alley side. The
existing yard divided the site diagonally, which, when combined with
the required side and front yards, reduced the buildable lot area to
60 sq. ft.
Fortunately, the client also owned the adjacent property. We
advised him to combine the northernmost corner of the trapezoidal lot
with his adjacent property, and have the two lots re-recorded. This
resulted in a rear lot line that was fully parallel to the front lot
line. A 10% reduction to the minimum lot area per unit restriction and
reductions to the usual yard requirements were then sought and
granted from the zoning administrator, resulting in a buildable
footprint of 1366 sq. ft.
The
building features two 1200 sq. ft. duplexed units with exterior decks
and balconies serving every primary room in each unit. The unit plans
are arranged diagonally on the site, thus permitting all main rooms to
have at least two primary views. This diagonal relationship is also
expressed in the split-level floor relationships within the units, and
in the exterior massing. The full masonry front portion features a
regular, unbroken pattern of tall windows, and its continuous parapet
conceals a roof deck serving the master bedroom across the full width
of the building. The rear mass is taller and narrower than the front,
and is clad in stucco. A vertical string of small windows signal the
recessed front entry and common stair. From the southwest corner, the
two-story porch and volume of the internal unit stairs reinforce the
diagonal massing.
