Double-height shelving and custom glass vitrines create ample storage space in this Amsterdam apartment, which was designed by local studio i29 to accommodate the owner's vast collection of art and books.

Located in a former industrial area in the north of the city, the 180-square-metre apartment is on the second floor of a residential block and belongs to a writer and art collector.

Built in 2020, the apartment block was set up as a Collectief Particulier Opdrachtgeverschap (CPO), which means collective private commissioning. In the Netherlands, this is a form of social project development in which a group of individuals act as the client for a new-build project.

The building is developed as a group and each owner buys an empty shell. They can then design and build partitions in their own apartment according to their specific needs.

Local studio i29 was commissioned to create a custom interior that would showcase the owner's expansive personal library and an art collection of around 100 pieces.

"Having such a huge collection of artworks, our client wanted only one thing: to have the ultimate display and storage space," i29 told Dezeen. "We started making a programme of requirements and calculating the exact amount of shelving we would need."

The designers were presented with an open loft space with double-height ceilings and no fixed layout.

On the ground floor, i29 created an open-plan space for the entrance area, kitchen and living room. A series of small sculptures are displayed on glass shelves in the kitchen, while larger artworks are placed up against the walls or mounted on them.

A mezzanine level was inserted within the double height space, housing a bathroom, two bedrooms and an office.

Two custom-designed larch wood storage walls span the full height of the apartment and include a mixture of cabinets and open shelving. They help to create a visual connection between the two levels, while concealing an integrated staircase that runs up to the mezzanine level.

The bespoke kitchen and all of the cabinets throughout the apartment are finished in a combination of larch and matt grey high-pressure laminate (HPL).

The floor is made from matching resin, as i29 wanted to keep the material palette deliberately neutral in order to let the art take centre stage.

"The stark and simple spatial interventions stand in contrast to the colourful pieces of art, balancing and supplementing each other," the studio explained.

In a similar apartment project featured on Dezeen earlier this year, EBBA Architects used structural ash and pine joinery – including a staircase, mezzanine and double-height storage wall – to connect the levels within a refurbished, open-plan apartment in London.
