The team of Korth Tielens Architecten and Marcel Lok Architect with project developer Heijmans Vastgoed, DS landschapsarchitecten, artist Martijn Sandberg and Fore installation consultants, has been selected to further develop their plan for the housing programme to be realised at the former Spaarndammer School site, Amsterdam. The Spaarndammer School site De Verbinding/Spaarndammerhart, is located in the Spaarndammerbuurt, an area of the city with listed residential housing, characteristic of Amsterdamse School architecture.

Atelier Rinzema and Martijn Sandberg started a project in the summer of 2020 that literally and figuratively builds on the earlier work of art 'I Am Still Alive' in metal. The letters 'I am Still Alive' are now embroidered on a white piece of fabric, each time with two different colors of thread. Stitch by stitch, the figuration 'I Am Still Alive' slowly becomes visible in the handiwork.

A selection of sketches by Martijn Sandberg for several aluminium cut paintings, size 100cm x 100cm - a.o. 'Im Westen nichts Neues', 'What Fun Canvas Done' and a series of nursery rhymes by the artist: 'Tip Tap Top De Verf Is Op' ('Tip Tap Toe The Paint Won't Flow').

Martijn Sandberg has made a design for a pedestrian bridge at Amsterdam Zuidas in collaboration with Atelier Rinzema, Haasnoot Bruggen, BPD | Bouwfonds Gebiedsontwikkeling and the municipality of Amsterdam. The pedestrian bridge is a connection for De Boelelaan to the Zuidas, near building The George. The design is made in close coordination with the municipality of Amsterdam and the bridge is offered by ZuidSchans C.V. (BPD & AM).

The site-specific artwork ‘Make Love Not War’ by Martijn Sandberg, forms part of the transformation of the former Tapijn Barracks (Tapijnkazerne), Maastricht. The barrack terrain was laid out between 1916 and 1919 and will now receive a new function as an urban park containing University of Maastricht buildings. The artwork figuration is incorporated in the paving of the main path, using bricks. It lies in the park-like surroundings of the former military terrain.

Martijn Sandberg has realised a site-specific artwork: an acoustic wall in the interior of the newly constructed Gorlaeus Beta Campus of the Faculty of Mathematics and Natural Sciences (FWN), University of Leiden. The artwork consists of connected perforated aluminium panels, covering the surface of the wall in the hall, vacant space and first floor of the building. The perforated artwork is twenty metres long, seven metres high and lit from within.

A rectangular paved artwork by Martijn Sandberg, is an integral part of the Kraaipan Square at the Hofmeyrstraat in the Transvaalbuurt, Amsterdam. Lines delineate a text in the paving, a hidden message to the square’s visitors, neighbourhood residents and passers-by. Over and over again when seeing it anew, today and every day: ‘Tomorrow everything will be alright’.

Martijn Sandberg's site-specific artwork on the concrete wall in the entrance hall of the Synagogue LJG in Amsterdam, refers to the location in a contemporary manner. While looking at the interplay of light and lines high on the wall, the contours of letters become visible. A radiant message appears to the visitor. A message from above. Art with a message - from yesterday, today and tomorrow. When entering and leaving the Synagogue. Over and over again, a vision for now and forever more: 'You have ten saved messages'.

'I Will Survive’. A contemporary reading of the Latin proverb ‘Ars longa, vita brevis’ - life is short, art long.

Martijn Sandberg has developed a plan for a site-specific artwork in connection with the renovation of the Ministry of Economic Affairs building on the Bezuidenhoutseweg in The Hague. Sandberg’s plan 'Na Regen Komt Zonneschijn' concentrates around the building’s two patios. Both patios mirror each other in the building, originally of such symmetry in its design.

The site-specific artwork 'Forever in Stone' by Martijn Sandberg, is an integral part of the architecture of the district Olympisch Kwartier, Amsterdam. Steel clinkers form the pixels of a figuration in the brickwork of the planters, meandering along the plinths of the housing blocks throughout the district like a banderole. By sampling the steel clinker in the brick grid of the banderole, a perpetual loop occurs: 'Stoned Forever', 'Forever Stoned', 'Stoned Again' and 'Again' written in stone.
