Foster + Partners is developing a sustainable masterplan for Maratué, located along Chile’s Puchuncaví coast. Commissioned by Inmobiliaria Maratué, the project will revitalize a vast 1,045-hectare area by reconnecting the town of Puchuncaví with its coastal surroundings while preserving the area’s stunning natural landscape. The plan envisions the creation of 14,000 new homes, including more than 2,000 units dedicated to social housing.
Juan Frigerio, Partner at Foster + Partners, shared that the sustainable masterplan is focused on preserving, linking, and enriching Maratué. He explained that a dynamic green corridor will run through the site, forming a seamless connection between Puchuncaví and the Pacific Ocean. With 650 hectares dedicated to conservation, parks, and public spaces, the natural environment shapes the overall design, uniting the various neighborhoods while giving each its own distinct character.
The development introduces two new residential districts—one adjacent to Puchuncaví and the other situated nearer the coastline. Each district is organized into three walkable, human-scaled clusters, centered around a green core. These green hearts are linked by a central landscaped corridor that weaves through the entire site. This design seamlessly incorporates nature into the urban fabric, delivering both ecological and social advantages while improving overall connectivity. The green spine also spans an existing highway that bisects the area, effectively reuniting Puchuncaví with its beachfront.
Ecologically sensitive areas are thoughtfully conserved and gently enhanced with features such as walking trails, wildlife viewing platforms, and wetland parks. In contrast, the central green spaces within each neighborhood are more deliberately designed, offering recreational areas and communal spaces for residents. Promoting wellbeing is a key focus of the masterplan, ensuring every resident is within a five-minute walk of a green space.
The coastal neighborhood will feature ocean-view homes and hospitality venues, helping to attract visitors to Maratué. A broad green buffer separates buildings from the cliff edge, incorporating walking and cycling paths to foster an active waterfront experience—while also preserving local ecosystems and natural wildlife habitats.
