Monumental says its robots have completed curved walls, varied brick bonds and indented lettering at a housing project in Almere, with another 15 houses due in the following weeks. Founder and chief executive Salar al Khafaji shared the work on 28 October, arguing that automation could make decorative brickwork more affordable by reducing reliance on costly skilled labour. The Amsterdam company reports a fleet of more than 100 robots and walls built for over 100 homes across the Netherlands and UK, alongside schools, commercial buildings and canal infrastructure.
Monumental operates three specialised robots: Pisa lays bricks, Petra supplies them and Panama manages mortar. Their movements are coordinated by Atrium, the company's software system for converting architectural drawings into brick-by-brick construction plans. Designers specify facade geometry and joint positions parametrically; Atrium computes placements, aligns plans with 3D scans of the actual site and adjusts execution using onboard perception. This connects variation in the brick pattern to software-generated placement instructions rather than individually setting out every decorative element by hand.
A 2025 transformer-building project near The Hague illustrates the engineering involved. The design called for vertical soldier-course bricks, whereas Monumental's existing vision and supply mechanisms had been developed for horizontal bricks. Its engineers updated the pattern model, worked on recognition of differently oriented bricks and built a slide that rotated them into position for robotic pickup. After iterations in 3D-printed parts, a metal mechanism was deployed and the transformer building's decorative brickwork was completed.
Monumental raised $32 million in a July 2026 Series B led by Khosla Ventures, bringing its reported total financing above $60 million. The company describes more than 40 delivered projects and a fleet of over 100 machines, with expansion into the US under development. Contractors hire Monumental as a masonry subcontractor and pay for completed walls rather than purchasing robots. Its UK offering includes patterned, indented and curved brickwork and soldier courses, alongside conventional masonry.
The Almere project extends that work into curved and patterned housing facades. Monumental’s robots use onboard perception to connect their digital wall plans with the geometry of the actual site, while its engineering team adapts brick presentation and tooling when a design introduces a new placement requirement.
