Living with pets is messy. Your home doesn’t have to be.

Traditional dog playpens and indoor dog pens are often designed as temporary solutions — bulky, awkward, or meant to be hidden away. They solve a problem, but create new ones in the spaces we actually live in every day.

Lucky Muffin Home Spaces exist to rethink that tradeoff. Designed to fit naturally into real homes, they create calm, comfortable boundaries for pets while respecting the way you live — without feeling like an afterthought or eyesore.

The Home Space system, designed for real life.

Lucky Muffin Home Spaces are built on a simple idea: pets need boundaries, but homes need flexibility.

The Home Space system is our approach to designing pet enclosures that adapt to real routines — spaces that can stay out, evolve over time, and feel considered rather than temporary.

  • Designed to Stay Out

    Home Spaces are designed to live openly in your home — with clean lines, calm proportions, and materials chosen for everyday visibility, not storage closets.

  • Flexible by Design

    The system is modular by nature, allowing layouts and components to adapt as needs change — from daily routines to different stages of life.

  • Built for Real Use

    Easy setup, easy cleanup, and durable materials are designed into every Home Space, so living with pets feels simpler, not more complicated.

Today, the Home Space system begins with Harbor — our open, modular Home Space designed for everyday living at home.
