Sarah Winchester employed a 24-hour construction crew that worked seven days a week, 365 days a year, for nearly four decades.
The house features a 'switchback' staircase that consists of seven flights of stairs with 44 steps, rising only nine feet in total height.
It is built on a shallow foundation, which allowed the building to survive the devastating 1906 San Francisco earthquake.
The house features 'spider web' stained glass windows, a design motif personally requested by Sarah Winchester.
Many interior doors open into sheer drops, leading to the nickname 'door to nowhere'.
The mansion was fitted with modern amenities early on, including central heating and internal plumbing, both rare for the period.
The floor plan contains a 'seance room' where Sarah Winchester purportedly communicated with spirits.
The mansion occupies what was once a 162-acre estate, though only a fraction of the land remains today.
Sarah Winchester did not use professional architects, instead drawing her own building plans on napkins and scraps of paper.
The Winchester Mystery House is a sprawling Victorian mansion in San Jose, California, famously constructed continuously for 38 years under the direction of Sarah Winchester. The architectural design features numerous structural anomalies, including staircases leading to ceilings, doors opening into walls, and windows facing internal hallways. Spanning 24,000 square feet, the mansion was built from an original eight-room farmhouse into a complex labyrinthine structure. It contains 160 rooms, 47 fireplaces, and 10,000 glass panes. The estate utilizes unique building materials like Tiffany glass and ornate hand-carved woodwork. It remains a historical landmark dedicated to the eccentric building habits of its original owner.
The front exterior facade from the garden entrance provides the most iconic view of the mansion's towers.
