A major residential construction project is moving forward in Baltimore County as developers break ground on Aspen at Greenleigh, a multifamily community expected to bring hundreds of new housing units to one of Maryland's largest mixed-use developments.
The $148 million project is being developed through a partnership between St. John Properties and Somerset Companies and will deliver 335 apartment units within the Greenleigh community near Middle River. Construction is scheduled for completion in late 2027.

The development continues the long-term expansion of Greenleigh, a master-planned community that combines residential, commercial, retail, and employment space within a single integrated district.
A defining feature of the project is the use of insulated concrete form construction, a building method that combines reinforced concrete with permanent insulating materials to create the structure's walls.
Developers say the approach offers benefits including enhanced structural resilience, improved energy efficiency, reduced noise transmission, and increased resistance to environmental factors such as wind and fire.
The project is expected to become one of the largest multifamily developments in North America utilizing this construction methodology, signaling growing interest in alternative building systems that can improve long-term building performance while supporting sustainability goals.
For contractors and owners, the project reflects broader industry efforts to balance durability, operational efficiency, and lifecycle cost considerations in multifamily construction.
The development team includes architects, engineers, designers, and construction specialists working across multiple disciplines.
St. John Properties' Multifamily Construction Division is managing construction activities, while project partners are providing architectural, structural, civil, mechanical, electrical, plumbing, and property management services.
The coordinated delivery model is intended to support efficient execution of a project that includes residential buildings, structured parking, amenity spaces, and supporting infrastructure.
Upon completion, Aspen at Greenleigh will expand the apartment inventory within the larger Greenleigh development to more than 1,000 units.
The broader community continues to evolve as a mixed-use destination that combines housing with commercial development, employment centers, retail services, and public gathering spaces.
Full build-out plans call for nearly 3,300 residential units alongside millions of square feet of commercial space, creating a substantial live-work environment designed to support long-term regional growth.
As housing demand remains strong in many Mid-Atlantic markets, large-scale master-planned developments continue to attract investment from developers seeking to deliver new residential inventory while leveraging existing infrastructure and amenities.
The Aspen at Greenleigh project highlights several trends shaping multifamily development, including the adoption of alternative construction technologies, growing investment in master-planned communities, and continued demand for higher-density housing options.
For construction owners and developers, the project demonstrates how advanced building systems and integrated project delivery strategies can support large-scale residential developments while addressing performance, sustainability, and long-term operational objectives.
