Wright and his team at Taliesin delivered over 900 drawings to contractors to support the construction of about thirty American System Built Homes (ASBH) built between 1915 and 1918, including this home. Many of the drawings are in the Avery collection at Columbia University. Others are at the Getty Museum.

Citing this vast body of work, ASBH historians have called the ASBH project the largest single design effort by Frank Lloyd Wright. We’re finding evidence to suggest that Wright  and Arthur L. Richards, his marketing partner, may have seen the heavy lift as a necessity.

Specifically, it was not economic or practical for Wright to visit or send an assistant to ASBH job sites, which could be anywhere and happen concurrently. Lacking architectural supervision, a builder needed as much clear instruction as could be delivered remotely. So no matter how small the home to be built, each project would require in-depth plans, including drawings, detailed bills of materials with a complex numbering system, inventory management and instructions for assembly. Thus, over 900 drawings.

As evidence, see an inventory numbering system, along with quantities and sequencing stamped and drawn on the back of a section of trim in the image below.

Presumably, 350 feet of milled lumber of the the shape called 60-455 would be assembled as the 54th step. (It is interested that Wright’s drawings call this item number B-11. Did Richards and Wright have their own lists?) The stamp was used at the lumber yard to control stock of a specific geometry. The colored pencil explained what was required to build a specific model of home. Historians with evidence to support or refine this interpretation are invited to comment or email.

Finally, so dependent on instructions like these were Richards and his subcontractors that Richards pleaded to Wright sometime in 1917, when Wright had gone to Japan to design and build the Imperial Hotel:

“every minute of your time is needed here… …you can make more money making plans”

Shortly after reading these words, Wright terminated his agreement with Richards to design ASBHs. The Elizabeth Murphy House was among the last in the program to be started, and was certainly the last to be finished. More on that in future posts.
