Adjustable Forms Inc.

Lombard, Illinois / United States of America

The owner, a cast-in-place concrete contractor, sought a building design that was a reflection of their work. The project was conceived as a vehicle to showcase the client's talents and capabilities while expanding the team's knowledge of concrete and it's potential. The project comprises an expansion and renovation of an existing office and warehouse facility. The design reuses the existing building's structural elements as much as possible. The existing concrete slabs were crushed and repurposed as granular fill material for new floor systems. 
Various methods of concrete construction were used throughout the project. Color, texture, and mix were explored and experimented with throughout the design process. A 40% fly-ash mix was predominantly used. The challenge of creating a fully sealed and thermally broken envelope was resolved by cantilevering a post-tensioned roof slab that provided a continuous thermal break at the perimeter between interior and exterior elements. 
The design limited the materials used to provide a pure minimalist aesthetic. Dark zinc panels were used to bring a stark contrast to the minimalist raw concrete massing. The zinc panel sunshade is an abstract representation of the form work being lifted from the concrete mass, what builders call "stripping the forms".
