Fitness entrepreneur Anne Mahlum is shifting her real estate focus toward a new 10-bedroom residential project. The expansive home is set to span between 12,000 and 13,000 square feet, designed specifically to accommodate hosting and family life.
Why it matters
This high-profile construction project highlights current luxury real estate trends where former founders prioritize expansive, multi-bedroom layouts for hosting family and friends. The project marks a transition in personal real estate for the business owner following her sale of a New York City loft.
The planned home will feature 10 bedrooms and encompass 12,000 to 13,000 square feet. This follows the 2025 sale of a New York City loft that was originally purchased for $2.75 million and listed for $3.1 million.

Homeowners planning large-scale additions or new builds should prioritize flexible communal areas that facilitate hosting guests. Consulting with an architect about custom design elements like mosaic tiles or rounded arches can help define the structural flow of your own family-focused space.
The takeaway
When designing for a growing household, focus on versatile floor plans that can adapt to different hosting needs over time. Prioritize architectural features that create a cohesive flow, such as shared living zones, to ensure the space remains functional as your family dynamics evolve.
