The first quarter at Marieviks Udde, where JM is building four quarters with 630 homes in total according to its project pages, plus a preschool and commercial space, on the peninsula south of Liljeholmsbron. Mary holds 135 apartments of two to four rooms in an L-shaped block designed by Wingårdh Arkitektkontor: a 27-storey tower and a seven-storey quay building, with a shared roof terrace and an orangery on top of the quay building. JM’s project page gives a preliminary move-in from March 2028, and AMF Fastigheter’s timeline for Marievik puts the first residents on the peninsula in the same month. Byggindustrin reported on 24 October 2024 that JM was under way on the peninsula ten years after buying the land, working five metres below the surface of Mälaren. The Marievik plan won legal force on 3 April 2023 and covers about 960 homes and 27,000 square metres of offices and other premises in total; Marieviksbadet next door opened in June 2025. The city says the park opposite the bath is planned to open in summer 2026, and AMF’s timeline has the temporary Marieviksparken finished in July 2026; JM writes that Plåtparken is based in Marieviksparken, right next to the quay bath, and that the park has gained more seating, green space, games and a basketball court.
