About This Home
As of May 2026217 Mansfield Avenue presents a rare opportunity to secure a full, flat acre in one of North Darien's most desirable and rapidly evolving neighborhoods. Set on beautiful, level land, the property currently features a charming but dated Cape Cod-style home ready for its next chapter. Buyers may choose to renovate and restore the existing residence, bringing new life to its classic bones, or take advantage of the exceptional lot to build a substantial new construction home. The surrounding area supports significant value, with many newer homes commanding prices in the $4M-$6M range. A standout feature is the detached garage with a legal accessory apartment above-ideal for guest quarters, rental income, au pair space, or a private home office/studio. Whether you're an end user looking to customize, an investor, or a builder seeking a premier site, this property offers flexibility, value, and long-term upside in a highly sought-after Darien location.
