What attracts tenants to a multifamily building? While competitive pricing, modern appliances, and attractive amenities can create interest, it is the building’s design that ultimately forms the foundation for how these features are experienced. Whether developing a new property or renovating existing units, design-forward elements such as bifold glass doors establish the framework for functional, marketable, and appealing spaces.
In multifamily building design, every square foot plays a role in both maximizing the developer’s ROI and enhancing the tenant’s daily experience. Incorporating natural light, energy-efficient features, and seamless indoor-outdoor transitions ensure that spaces, regardless of size, feel open, connected, and livable.
