Before and After in New York: With the big steel framed windows and doors the back alley becomes a true garden.

Rietveld Architects New York @rijk-rietveld.bsky.social · 27/08/2026

Before and After in New York: The rear wall was all small windows at both floors. We changed them into large windows. Big structural change for a building with 13 floors. The approval process was grueling, but it worked.

Before and After in New York: In this case the apartment was fully redone, but super boring. Left: dark and narrow. Right: take walls away and open up floor as big as structurally possible.

Also small apartments deserve no corridor. This one is in The Hague.

Sort corridor as well as enfilade. 16 out of 24 windows with four exposures all spatially interconnected

The Hi-Con stairs were only 90mm thick. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

Before we got the green light to use the thin ultra-high-performance-concrete (Hi-Con) stairs, we were looking for thin stair edges as the expression. Variations to put the structural part in the middle and taper them to the edges with slanted or curved lines

Rietveld Architects New York @rijk-rietveld.bsky.social · 28/02/2026

We were worried that the glass fire rated wall would become too transparent and would dematerialize the space and create an Escher effect in the stairs. I made a lot of studies to see the effect. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

On this photo you can see the triple-layered stair separated by a 60 minute fire resistant glass wall. By zig-zagging the fire break vertically over the middle flight, both stairs can be open to double height compartment. A world premiere.

Another cool feature of this building is the triple-layered scissor stairs. By zig-zagging the fire break vertically over the middle flight, both stairs can be open to double height compartment. A world premiere. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

The wharf edge is more than 100 years old. The existing section is amazing. The hollow part is to slow down silting. The wood rig is buried to avoid toppling. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

Trying to step away from the traditional enclosed beam structure. Try #7 is where the structure became a tree supporting the roof from which the building was hanging. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

Our friend Ard Buijsen went with his son Jente to orientation at our building for InHolland at Delft University and sent me this picture. I had no idea that our American SARA Architecture Award was on display there together with the 3D printed model and rendering.

This was the start of the solution. Trying to avoid structure in the underpass along the water. So we proposed to use the roof as the primary structural plain with the main floor hanging from the roof edge with steel frames in the facade: Amvest's headquarters on Cruquius Island, Amsterdam.

At the same time we were working on the two apartment buildings completing the urban block. One block was middle rent and the other were free market units. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

A study if we could make the cantilevering beams out of glass. Glass is great with compression, steel with tension. A fully transparent construction without diagonals has never been done at this scale. This was a bridge too far. Early sketches of Amvest's headquarters on Cruquius Island, Amsterdam.

Best wishes for 2026. I found this old sketch from 25 years ago. It was a concept of stacked duplex villas Le Corbusier style. This was still drawn with a fountain pen on paper.

After the fires in the Palisades, there was an Instagram video with a house completely destroyed. Everything was gone but the porcelain KLM houses. Having travelled everymonth for 40 years between NY and Amsterdam we have quite a collection and we were able te send her close to 100 different houses.

Spyker built roughly 250 cars in the period from 2000 to 2015. Now, 10 years later Victor and Jasper are combining forces to produce a new series of Preliators. The Spyker motto is Nulla Tenaci Invia Est Via. For the tenacious no road is impassable. #spykerenthusiast #spykercars #spykerowner@spyker
