Andover carries 3 office buildings with 27 units between them, at 300 Brickstone Square and 800 Turnpike Street, the latter address continuing into North Andover. Three separate properties are enough for a genuine comparison — a tenant in Andover can hold two viewings against a third and still be looking at the whole 27-unit pool.
Asking rents in Andover span $275 to $446 per m² a year, with the median at $332 — the top decile stands 62% above the bottom one. Such a gap inside a pool of 27 units is negotiating room rather than noise: two suites of similar size can land on opposite sides of the $332 median depending on the building, the floor and the state of the fit-out, which is why a shortlist in Andover should cross all 3 addresses before any figure is discussed.
Sizes in Andover run from 5 m² to 530 m² with a median of 75 m², so most of the 27 units are compact suites; the 530 m² end exists, but as a single option rather than a segment. A tenant expecting to double a 75 m² footprint should establish in advance which of the 3 buildings can release a second unit on the same floor.
Andover lies in the Merrimack Valley on the I-93 and I-495 ring north of Boston, and no rail station is counted in its transit data (0), which puts the weight on parking ratios at the Brickstone Square and Turnpike Street addresses. That road position also explains a tenant base built on suburban back offices and technology firms; with 27 units listed in total, availability is tracked building by building rather than through a broad search.
