Ring metro, green wedges
Balances expansion with mountain landscapes
The Sofia General Development Plan, prepared by the municipal planning institute Sofproekt and carried forward through the 2010s towards a 2030 horizon, is the Bulgarian capital's statutory master plan. It structures growth around an expanding metro network, including orbital and radial lines, while protecting a system of green wedges that connect the city to the Vitosha mountain to the south. The plan seeks to channel post-socialist market development into corridors served by public transport rather than dispersed peripheral sprawl.
The plan is significant as an attempt to reassert comprehensive planning in a post-socialist capital where restitution and rapid private building had weakened public control. Its pairing of metro-led corridor development with landscape protection places it within the wider European turn to transit-oriented planning, and it is frequently discussed in debates on how Southeast European cities manage growth pressure against inherited green-space systems.
