Two Office Deals Point To Aventura’s Growing Pull

Consor Engineers and Mifel have signed office leases totaling 10,322 square feet at Onyx Tower in Aventura, adding an international entrant and a relocating Miami-Dade business to the O Towers tenant roster. Blanca Commercial Real Estate closed the transactions, which includes 8,434 square feet for Consor Engineers, relocating from the Miami Airport area, and 1,888 square feet for Mifel, entering the market from Mexico.

The leases reflect two sources of demand for Aventura offices: companies establishing a local presence and existing Miami-Dade tenants choosing a different submarket.

Aventura’s Vacancy Falls As Rent Gap Persists

According to Blanca’s third-quarter 2026 Miami-Dade office report, Aventura’s direct vacancy declined to 12.9%, compared with 16.5% a year earlier. The 3.6-percentage-point decrease was among the largest recorded across the major submarkets covered in the report.

Aventura’s Class A asking rents averaged $67.38 per square foot on a full-service basis, approximately 42% below Brickell, where Class A vacancy was below 6%.

Those figures position Aventura as a lower-cost option for companies comparing Class A space across the county. At the same time, its falling vacancy indicates that tenants are absorbing more of the submarket’s available inventory.

New Arrivals And Demand For Ready-To-Occupy Space

The latest Onyx Tower transactions follow other corporate moves into Aventura. Big Think Capital relocated from New York to O Towers earlier this year, while Comp AI moved its headquarters from New York to Aventura View.

At Aventura Corporate Center, where Blanca also serves as exclusive leasing agent, renovated spec suites are now ready for occupancy. Nearly all suites in the initial round were leased before renovations were completed, providing another indication of demand for ready-to-occupy offices.
