Der Stadtteil Heerdt, insbesondere die vormals industriell genutzte Zone südlich der Hansaallee, durchläuft seit Jahren einen städtebaulichen Wandel. Die ehemals durch die Firmen Schiess und Impress genutzten Industriegrundstücke zwischen Hansaallee und Willstädter Straße im Süden und Böhlerstraße im Westen transformieren sich mehr und mehr zu einem attraktiven Wohnquartier. Grundlage der Neubebauung des Quartiers „Vierzig459“ bildet ein Masterplan, mit dem 2013 das Planungsbüro nps tchoban voss in Zusammenarbeit mit JKL Landschaftsarchitekten aus Georgsmarienhütte den städtebaulichen Wettbewerb für sich entscheiden konnte. prasch buken partner architekten, die sich 2015 aus dem Hamburger Architekturbüro nps herauslösten, entwickelten das Projekt weiter und übernahmen in den vergangenen Jahren zudem die Gebäudeplanung einzelner Baufelder. 

The mixed-use character of the district inspired a distinctive master planning strategy: defining the 12-hectare residential quarter as an inward-focused community. The centerpiece is a sprawling central park anchored by a substantial lake—a design that creates inviting public spaces while managing rainwater runoff during heavy storms. Four distinct residential zones flank the lake and a new circulation route, where staggered apartment blocks up to six storeys frame open block perimeters. The interiors feature three- to five-storey terraced and townhouses, creating a layered hierarchy that shields quiet, pedestrian-priority courtyards from vehicle traffic. Parking is ingeniously hidden: mostly in underground structures, with commercial parking consolidated in a dedicated garage on the site's southeastern edge. A five-classroom kindergarten anchors the lakeside park, while a tree-lined "Broadway" promenade—stretching diagonally from the cinema at Hansaallee to Willstädter Straße—activates ground floors with shops, cafés, and restaurants alongside residential units and services above. A thirteen-storey residential tower marks the intersection of lake and promenade, serving as a striking gateway to the quarter. Since mid-2016, a joint venture between Die Wohnkompanie NRW and Bauwens Development has realized the plan across five construction phases. The inaugural phase delivered approximately 350 units across four blocks: staggered cube-form buildings framed by four- to five-storey wings, with flowing courtyards serving as both access and community gathering spaces. Across construction parcels 2.6, 2.7, and 2.8, pbp Architekten shaped this opening phase with over 190 units, implementing the master plan's signature design code of "hard shell, white core." Exterior facades showcase clinker brick, while courtyard-facing elevations feature light plaster with carefully considered color accents. The freestanding parking structure—also designed by the Hamburg office—houses 670 spaces beneath two retail frontages. Its dual expression is deliberate: a brick base grounds the structure, while an expanded metal lattice upper facade provides both acoustic shielding and ventilation.
