10 House Plan Collections to Know About (and Why People Love Them)
When you’re building a home, it’s easy to get caught up in square footage and bedroom count. But sometimes, it’s one specific detail in a house plan that makes everything click—like a tucked-away suite for in-laws, a garage with space to live upstairs, or a porch that was clearly made for morning coffee. Maybe it’s a floor plan that gives everyone a little breathing room, or a tiny home that feels just right.
Architectural Designs’ plan collections make it easy to skip the endless search and head straight to the designs that fit how you want to live.
