Project Challenge:
Hopkinson House is a significant example of modern architecture
of the 1960's. Originally designed in 1961 by noted modern architect,
Oscar Stonorov, the reinforced concrete building is located
within an urban historic district and is considered a contributing
resource to the historic community. The unique balcony arrangement
and variation of window types not only served to define the
character of the building, but also became the primary challenge
of the project.
Project Solution:
Concerns about water and air infiltration as well as localized
deterioration and potential safety hazards prompted the council
of this 32-story condominium building to retain Klein and Hoffman
(K&H) to perform an investigation of the original sliding
windows and doors.
K&H's report identified existing deficiencies, compared
the advantages and disadvantages of rehabilitative options and
ultimately recommended a building wide window and door replacement
program.
K&H worked with the council and the building management
to develop a comprehensive replacement program for 2,170 window
and door units that provided high performance and high energy
efficiency while maintaining the original layout of this award-winning
building.
Other significant challenges included obtaining Historic Commission
approval for the replacement windows and performing a building
wide window replacement program in an occupied building. K&H
worked closely with the building management and contractor to
make the installation as unobtrusive as possible for the unit
owners.
