The first of the four JM quarters at Marieviks Udde, roughly 620 condominiums with a preschool and commercial space on the peninsula south of Liljeholmsbron. Mary holds 135 apartments in one 27-storey and one seven-storey building, according to AMF Fastigheter’s timeline for Marievik, which puts the first residents in October 2027. 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 opened in June 2025 and the park opposite is due in summer 2026.
