Quick Take — Filed, Not Approved
MITRE wants to trade office for housing next to McLean Metro, and the math around that trade will set expectations in Tysons for the next two years. Filed July 2 2026, not approved — pending Fairfax County acceptance per FFXnow July 2026 — the proposal is 2 high-rise offices — 24 and 16 stories — plus 890 dwellings in three 8-story buildings, nearly 3 acres of park, on about 22.5 acres at 7525 Colshire Drive in Scotts Run. Three existing MITRE buildings stay, Mitre 1 would be demolished under the filing.
What Was Filed July 2
Cornerstone Analysis – Fact: what was filed. Today MITRE has 4 buildings plus 2 garages plus surface lot per FFXnow July 2026. Under the Feb 2018 master plan it could have built 5 more offices. The July 2026 revision concentrates offices north closer to McLean Metro and trades south to housing accessed from Commons South Street with park spaces integrated between buildings. That is still an application, not an approval, early-Aug per County — check County case tracking for current acceptance. Fact source is FFXnow July 2026, early-Aug check, verify acceptance status.
Where 890 Would Go

In Tysons, walkable pockets with park plus grocery have held about 4% to 7% better than car-dependent parcels same ZIP per our 2025-2026 tracking to early Aug — Cornerstone analysis from 6-person bilingual team and 250-plus families sample, not appraisal, analysis not guarantee.
