Open stairs was also a focal point for this school in The Hague. The classes are wrapped around the central gym. There are four open stairs in the double height corridors with daylight from above. There are no enclosed escape stairs. Successful concept with Peter van de Leur.

The logical next step in the quest for open office stairs was to actually make both of the stairs very wide and completely open and not have an enclosed escape stair at all. By locating the restrooms at the landing level, everybody uses the stairs (except for the handicapped). Faxx office building in Tilburg.

It's an ugly sketch, but it's the idea that counts....

Another variation of "open" stairs is in the INHolland University in Delft. We designed multiple scissor stairs, with four permanently open (electro magnetic- closes when there is a fire alarm) doors per staircase. The fun part was to make the scissor stairs with no separation wall, giving it a spatial M.C. Escher effect...

In 2009, we built the first "open" escape stairs for Interpolis office building in Zoetermeer. The corridor went straight through the free form core stability walls. The doors are permanently open on electro-magnets and will only close in case of fire. That way the stairs were open to the offices. Interpolis was at that time already promoting stair use over elevator use for health reasons.

Not a hand-drawn floorplan, but this is the way we had six open stairs in the floorplan, and no enclosed escape stairs. The school wants to encourage the use of stairs...

Almost 15 years ago we were working on plans for the InHolland University to have a new building on top of the roof of the old Ringers Chocolate Factory in Alkmaar. The biggest innovations were the exploded core (no corridors) and the six open stairs configuration (no enclosed escape stairs. A specialty of us, together with Peter van de Leur).

First sketch of the Martha's Vineyard house.

This one has a photo behind it. White lines on a black background in PowerPoint.

Nowadays every sketch I make is digital, but they are still made by hand. Not of these are AI computer-generated. I use a digital pen on a large size Wacom screen........ 6

This one, from last year, has a full computer 3D model behind it.

This one, from early this year, has nothing behind it. No helplines, just proportons, and that gave it some extra swung.

This one, from last month, has just an image behind it. No helplines, just proportons, and that gave it some extra swung.

Lobby level for a big lawyer office competition in Amsterdam. I lost the pitch in a fraction of a second by asking if every partner would give up 1m2 (10SF) of their office "right" to improve the common areas. The partner on the jury started screaming at me: "I worked hard for this office and I'm entitled to my full 38m2". In three seconds I lost the competition.... 3
