Hilary Duff’s home situation in Beverly Hills, CA is what happens when classic architecture meets “family life, but make it glamorous.” She lives in a 5,260-square-foot renovated Georgian-style estate tucked inside the Summit neighborhood of Beverly Hills, a gated enclave known for privacy, hillside views, and celebrity-owned estates – and yes, it comes with the kind of details that feel equal parts charming and over-the-top, like a chicken coop, a pool with a slide, and a backyard clearly built for real living, not just show.

But once you look past the fun extras and celebrity polish, the real question is what does it really cost to live in Hilary Duff’s neighborhood –and for anyone trying to size it up, even a quick pass through a home affordability calculator starts to reveal just how exclusive this pocket of Beverly Hills really is…

“Working with an experienced architectural and design team is essential to achieve both the clients’ aesthetic goals and to maintain and potentially increase the value of a property,” notes Tammy Randall Wood, ASID, owner and Principal of Interior Archaeology, a full-service interior architectural and design firm specializing in high-end residential projects. “Clients typically spend between 8% and 15% of total construction costs on architectural and design fees, depending on the size and level of detail a project requires. The merit of those costs is realized in the ultimate value of a home –both in dollars and lifestyle.”
