Warsaw | Marlena Happach

A city architect who came from activism. Marlena Happach started out in a residents' association working on participation in local planning, and now runs Warsaw's architecture and spatial planning office. We talk about the real dilemma of her job: the city needs to densify to work well, and some residents will lose greenery, light or a familiar view because of it. Can you reach a compromise? Plus: Plac Pięciu Rogów, narrowing the lanes on Aleje Jerozolimskie, and what Warsaw might look like in 30 years.
