Plesmanduin is a redevelopment of the former KLM head office on Plesmanweg in The Hague, Netherlands. Designed by Dirk Roosenburg and built in 1938 and 1946, the approximately 30,000-square-metre listed monument later housed the Ministry of Transport and Water Management until 2017. 2
The project restores the historic office building and adapts it for residential and mixed use. Its 166 homes include social housing, owner-occupied apartments, two-storey city houses, homes for expatriates, penthouses and short-stay accommodation for international knowledge workers. Supporting uses include office space and hospitality in a pavilion. 2 Restoration work included the building’s façades, entrance halls and stairwells; new outdoor spaces and roof patios were added while keeping changes subordinate to the listed structure. 2
Focus on Impact Rotterdam is identified as both the client and developer, with Architektenkombinatie as designer. Van Wijnen carried out the transformation. 2 The wider development also includes a second phase of new apartments behind the monument, with a sunken car park and a landscaped dune above it. 2 The NRP project page describes this phase as 155 apartments; a later project source describes the next phase as 157, so the figures appear to reflect different project updates. 23
The conversion began in 2021, according to Van Wijnen, and the first residents were expected to move in during the second quarter of 2023. 4 Plesmanduin was among the projects nominated for the 2025 NRP Gulden Feniks, a Dutch award for renovation and transformation of the built environment. 5
