Master-planned Communities
These multifaceted developments require big-picture thinking and dedication for the long haul. CORE has supported many visionary clients to realize these ambitious projects, some lasting for decades. We integrate land use, economic development, transportation, lifestyle, and policy considerations into a viable plan.
Community comes in many forms—apartments, condominiums, townhomes, senior living, or single-family neighborhoods—people want a place to call home. There is no one-size-fits-all approach. Authentic community comes from thoughtful planning, tailored design, and public engagement.
We know the nuances of commercial development. Retail, mixed-use, hospitality, office, medical, industrial – each of these projects have specific end-user requirements. Our early involvement and integrated suite of services ensures the final deliverables meet those requirements.
