The Alliage is 12 residences on West Avenue, in a part of South Beach where large condominium towers dominate. With 12 units, one sale reshapes the building's price record.

The plans are lofts, with double-height living spaces and ceilings up to about 18 feet, at roughly 1,170 to 1,260 square feet. The sizes sit in a narrow band. With only four plans, the best comparable is the same plan on a similar floor.

West Avenue runs along the bay side of South Beach, with Biscayne Bay to the west and the Art Deco district and ocean beach to the east. The 1400 block is south of Lincoln Road, Sunset Harbour is to the north, and Flamingo Park and the Fifth Street restaurant district are to the south.

The address is walkable to the Lincoln Road pedestrian mall and the bay-side seawall, and a few blocks from the ocean. Dining and retail turn over and are not listed here.

The parcel is in FEMA Zone AE. Ask about flood insurance and the garage's flood history and mitigation before offering.

The building has four levels over an underground garage, an elevator, and a rooftop pool deck.

Unit mix. Four plans, all two-bedroom, two-bath, from about 1,170 to 1,260 square feet. Most are split-level, with a tall living volume and a sleeping loft or lower level. Get the specific layout and which level the bedrooms are on.

Amenities. A heated rooftop pool, sundeck and barbecue area. Parking is assigned and covered, in a garage under the building; ask for the number of spaces per unit.

Ask for the current budget and recent financial statements and reserve funding. Florida's milestone inspection and structural integrity reserve study (SIRS) rules apply to condominium buildings of three or more stories. Ask for the inspection report, the reserve study, and any repair scope or assessments.

With 12 owners, an assessment is divided among few units. Ask about elevator, garage waterproofing, roof and pool-deck condition, and whether reserves are fully funded. Ask for the master insurance policy, flood coverage and deductibles.

Pet, rental and minimum-lease rules are set by the association; confirm at offer stage.

One recorded sale, June 2025, at $880,000. It is one sale, not a building price.

Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Know the plan. Ceiling height and the split-level layout vary by unit. Get the floor, plan and parking assignment.

Price flood and insurance. The Zone AE designation affects insurance cost, and lenders may require flood coverage.

Read the documents. Request the budget, financial statements, reserve study and assessment history.

Sell the loft. Lead with ceiling height, glass and the rooftop.

Have the documents ready. Budget, reserve study and insurance declarations shorten diligence in a 12-unit building.
