MacCracken Robinson Architects (MRA) was tasked with designing new office space for a venture capital firm in the historic North Beach District of San Francisco. The 1908 building is a typical brick and timber two story structure, which had endured multiple invasive remodels that covered original materials and finishes, partitioned spaces and introduced suspended ceiling tiles.
MRA restored the original open spaces, reconsidered the layout to suit the user and introduced a new primary open stair to create a stronger connection between the two levels. The stair combines blackened hot rolled steel and thin European white oak treads and risers, which waterfalls down the bent steel base. Bolts and connections are left exposed as an honest expression of construction, while expanded steel mesh creates a layer of transparency that provides privacy, yet reveals movement.
A large skylight was added to further highlight the stair and bring natural light to both floors in the center of the space. Heavy timber structural members and existing brick walls were exposed where possible, creating a foundation of warmth and texture to receive new building components and materials that are primarily natural, sustainable and complementary to the original elements.
The stair and podium are screened from the circulation ramp by three custom 3D printed parametric panels derived from the skeleton of a precast concrete cladding panel. The panels serve a dual purpose of creating a semi-transparent barrier between circulation areas and act as an immediate showcase of the clients mission to find/invest in new and exciting companies in the construction & engineering industry.
The ground floor provides a public space for the client’s use, entertainment, and gatherings, with the upper floor consisting of a large main conference room, open work areas, private offices and a small gym. The peripheral spaces are full of natural light, yet are able to maintain visual privacy from the open office areas with the use of translucent fabric curtains. Acoustic separation was a primary concern for the client, so MRA worked with Salter-Inc to engineer custom steel window/doors and isolate enclosed rooms from adjacent occupant noise.
