House Plans with Dens

Imagine having a space in your home that adapts with you—a spot for everything from work calls to family movie nights. Our collection of house plans with dens is designed to do just that, adding a cozy and functional room to your home that can grow with your needs. Whether it’s your home office, a quiet study corner for the kids, or a comfy nook for movie marathons, a den gives you that extra room to make family life a little easier and a lot more fun.

With these house plans, flexibility comes built in. Today, your den might be a playroom filled with toys, tomorrow, it could be a gaming hangout for teens, and one day, it might even welcome overnight guests with a pull-out sofa or Murphy bed. A den, or flex room, keeps up with the rhythm of your family, ready to become whatever you need it to be.

And it’s not just about space—it’s about creating a spot that brings everyone together. Picture game nights, craft sessions, or a cozy reading corner. Adding a den to your home plan can create the perfect go-to space for bonding, relaxing, and making memories. Browse our house plans with dens, many featuring 360° interactive tours and client-build albums, and find the design that feels just right for your family’s unique style with Architectural Designs.
