Modern Design: Multi-Slide Doors

When Patrick O’Neill of Greenline Fine Woodworking was called to do a historically sensitive update to one of Pietro Belluschi’s last projects, it came with a very cool addition: a meditation room designed collaboratively with Michael McCulloch, a noted Portland architect who is the current owner of the home.


Project Goals

The intention of the design was to create a space that would blur the lines between indoors and out, minimizing visual interruptions and allowing the space to open completely to the exterior as much as possible.



Large, sliding full-lite doors can have challenges related to weight, stability and smooth operability. An additional challenge was to figure out how to allow the doors to meet at a corner with a only a narrow post to camouflage and complete the seal when closed.


Uniquely Versatile Solutions

A tricky mitred corner for the track system allowed the two layers of doors to meet seamlessly in the corner. Very tight tolerances were needed to ensure a weather-tight fit when the panels were closed.

The Versatile Product Design team worked closely with the installing contractor to ensure measurements were accurate and the design parameters could be met.

Bringing multiple tracks together in the corners presented alignment challenges for both the upper and lower panel tracks. The low profile sill makes for a near-flush transition to the interior flooring. Metal tracks were inlaid into solid wood sills to create an elegantly integrated system.

The result: a glowing oasis of thoughtful Mid-Century design that feels like an organic part of this architecturally-significant Oregon home.
