Iron Branch Homes for Sale in St. Augustine, FL

Iron Branch is a Toll Brothers enclave of 54 single-family estate homes, each on a roughly 1.5-acre homesite behind a gate. Four plans were published at opening, the Arcadia, Andrea, Flint, and Beckingham, running 3,749 to 4,710-plus square feet with 5 to 6 bedrooms, 3- and 4-car garages, in one- and two-story designs. The architecture is Toll's current modern-traditional Florida vocabulary: bright open living, gourmet kitchens, covered lanais, and the kind of structural flexibility a one-and-a-half-acre lot allows.

The option list is where Iron Branch separates from the rest of St. Johns new construction. Toll offers multi-generational suites, RV garages, and accessory structures here, which is nearly unheard of in this county's subdivision product. The lot supports real pools, courts, and gardens, so the homes are designed to be a base for the acreage, not a box that fills it. Optioned builds on premium lake or preserve sites will run well above base.

This is to-be-built new construction, not a resale stock with an era and a renovation history. Plan on roughly 10 to 14 months from contract to closing for a to-be-built home, design appointments and permitting included; quick move-in homes compress that to weeks or a few months. The build runs contract with structural options, then Design Studio selections, then construction with pre-drywall and final inspection points worth attending.

Day to day, Iron Branch life is acreage life behind a gate. With only 54 homes on one-and-a-half-acre sites, internal traffic is minimal and the streets are genuinely private. The amenity is the land itself: a 14-acre lake with a dock overlook for fishing and sunsets, and an open-air pavilion with water views as the community's front porch. There is no pool, gym, golf course, or clubhouse inside the gate, by design.

The setting is unincorporated St. Johns County's rural western corridor, west of downtown St. Augustine and south of World Golf Village, amid preserved farmland, ponds, and open space. Daily errands run to the SR-16 / World Golf Village commercial node roughly 12 to 15 minutes away; downtown St. Augustine is about 25 minutes, the beach about 30, and a downtown Jacksonville commute runs 40 to 45 minutes via I-95, which Toll publishes as about 10 minutes from the gate. If you measure life in walkability, this is the wrong community; if you measure it in acreage and quiet, this is the trade you are buying.

Acreage new construction earns more diligence than a subdivision lot, not less. Work this list before you sign.

• Verify water and sewer versus well and septic on the specific homesite, plus the irrigation source for 1.5 acres of yard; this corridor frequently runs on wells and septic, which changes monthly cost and inspection scope.
• Confirm the HOA assessment and any capital contribution in writing; Toll had not broadly published the dues at opening.
• Check the tax roll for any CDD or non-ad-valorem lines for the parcel; nothing in Toll's materials advertises a CDD, but verify rather than assume.
• Pull the FEMA flood panel and the lot grading plan on pond-adjacent or low-lying portions of the 1.5-acre site, and get a real insurance quote on the specific lot.
• Read the recorded covenants against your actual plans, the shop, the boat, the RV, the pool, the animals, before you commit; this is a deed-restricted community with architectural control, not open agricultural land.
• Confirm the lake-use rules (kayaks, fishing, electric trolling motors) and never pay a water premium for a use the documents do not grant.

Iron Branch occupies a narrow niche, so the cross-shop list splits two ways: other St. Johns luxury and other acreage.

The pattern: Iron Branch is essentially the only place in St. Johns County currently combining acreage, a gate, and a national-builder new build with a warranty. New construction here overwhelmingly means 40-to-80-foot subdivision lots; acreage usually means older rural homes or scattered custom builds with no gate. If you want an amenity ecosystem or a lower price, the alternatives win. If you want the land, this is the one.
