Presidio Terrace Residence — Scan-to-CAD Documentation
San Francisco, CA | Historic Residential | Existing Conditions Survey
Presidio Terrace is one of San Francisco's most architecturally distinguished addresses — a private gated community developed in the early 1900s, lined with estate homes that represent some of the finest residential architecture the city produced in that era. When the architect engaged LiDAR Precise Plans to document this single-family residence, the project came with a challenge common to historic homes of this age: no existing drawings of any kind.
Starting from zero, the team deployed a Leica RTC360 3D laser scanner to capture the property in full — interior and exterior — producing a comprehensive point cloud that became the foundation for a complete set of architectural documents.
What Was Delivered
From the scan data, LiDAR Precise Plans produced floor plans, reflected ceiling plans, interior and exterior elevations, a site plan, a roof plan, and a floor levelness study. Together these gave the architect a dimensionally accurate, construction-ready record of a building that had never been formally documented — delivered far faster than traditional field measuring could have achieved.
The Floor Levelness Study
For a home of this age, the floor levelness study was particularly valuable. Early 20th century residential construction settles and shifts over decades in ways that are invisible to the eye but consequential to design. The scan data produced a precise deviation map across all floor surfaces, giving the architect a clear picture of where differential settlement had occurred and how those conditions would affect the renovation scope.
Why It Matters
Historic single-family residences rarely have accurate drawings on file, yet renovation and restoration work demands precision that manual measurement struggles to deliver — especially across complex rooflines, period millwork, and irregular floor plates accumulated over a century of living. 3D laser scanning removes that uncertainty at the outset, giving architects the confidence to design without discovering costly surprises in the field.
