Didden Village is a rooftop extension completed in Rotterdam between 2002 and 2006. Set above a monumental townhouse and atelier, the project distributes two-bedroom volumes across a 120-square-meter terrace, transforming the roof into a shared domestic landscape of rooms, circulation, planting, and outdoor occupation.

Rooftop Addition as an Urban Strategy
Didden Village occupies a roof that might otherwise have remained a technical surface, recasting it as a site for domestic growth. The intervention adds 45 square meters of enclosed space and a 120-square-meter terrace above an existing monumental Rotterdam townhouse and atelier. Rather than extending outward into a rear garden or increasing the building footprint, the project directs expansion vertically, exploiting the often underused capacity of the urban roofscape.
This approach places the project within a broader question of densification in established cities: how can new domestic space be introduced without erasing the character or spatial continuity of existing fabric? The addition does not imitate the brick construction, slate roofs, dormers, and chimney stacks that surround it. Its separate formal language makes its temporal position explicit, allowing the historic building below to remain legible as a distinct substrate rather than an image to be replicated.
Seen from adjacent roofs, the small blue volumes appear as a compressed settlement above the continuous field of pitched roofs. Their visibility is deliberate. The project treats the roofline as an active urban horizon, where additions can register the changing needs of domestic life while leaving the street-level grain and perimeter of the block largely intact.
A Domestic Village Above the Street
The extension avoids the conventional logic of a single enlarged rooftop box. Two compact bedroom volumes are separated across the roof, creating an outdoor territory between them. This dispersal produces spaces that can be read as streets, alleys, and small plazas, borrowing the organizational language of a settlement for an individual household. Each room gains a separate address within the rooftop field, while the open terrace becomes shared ground.
Privacy is constructed through distance, orientation, and parapet walls rather than through a continuous internal corridor. Moving between rooms requires crossing the exterior, making weather, daylight, planting, and views part of everyday domestic circulation. The arrangement also complicates the usual opposition between room and terrace: the outdoor surface is not an ancillary balcony but the principal connective space of the upper level.
The parapet is developed as an occupied perimeter rather than a minimal safety edge. Slot windows and smaller openings selectively restore views toward trees and neighboring buildings while limiting direct exposure. Cantilevered benches, planters, tables, and outdoor shower elements extend the range of domestic use across the roof. These components give thickness and programmatic weight to the boundary, converting enclosure into an inhabitable architectural element.
Structure, Access, and the Construction of a New Ground Plane
The apparent lightness of the rooftop village depends on a structural system that mediates between new construction and the existing building. A steel beam grid distributes loads across the underlying structure, allowing the deck, parapets, and enclosed volumes to be positioned above the historic fabric without relying on a simple point-loaded arrangement. The structural frame establishes a new horizontal datum, effectively constructing an elevated ground plane over the townhouse.
Two spiral stair cores connect the interior of the existing house to the roof. Their role is more than functional. By establishing a direct vertical sequence from the rooms below to the terrace, the stairs incorporate the addition into the daily geography of the residence. The roof is not treated as a detached pavilion reached by a secondary route, but as another inhabitable level whose exterior circulation expands the spatial range of the house.
The exploded axonometric clarifies the project’s layered construction. The existing townhouse forms the base; the stair cores rise through it; the steel grid spreads above its walls; and the terrace deck, parapets, landscape elements, and gabled rooms occupy the uppermost layer. This separation of systems is instructive because it preserves the distinction between old structure and new intervention while making their technical dependency visible.
Blue Surface, Interior Contrast, and Architectural Legibility
A continuous blue polyurethane coating unifies the terrace floor, parapet walls, room exteriors, benches, planters, and other rooftop fixtures. This material decision suppresses distinctions between building, furniture, and landscape infrastructure. Instead of reading as isolated objects placed on a roof, the volumes and their surroundings become a single chromatic terrain, with planted trees and openings introducing localized interruptions to an otherwise continuous field.
The coating also heightens the abstraction of the two gabled rooms. Their pitched profiles evoke the simplified image of a house, yet the absence of eaves, conventional trim, and differentiated cladding reduces them to sharply outlined silhouettes. Against Rotterdam’s generally muted roofscape, the blue surface makes the addition immediately legible as a contemporary layer. It does not seek visual continuity through material imitation, but establishes a controlled contrast that clarifies the distinction between inherited fabric and new occupation.
Inside the bedroom volumes, birch plywood lines the walls and pitched ceilings, revealing the full geometry of each small house. The warm grain of the timber establishes a material counterpoint to the saturated exterior, while large glazed openings make the blue terrace appear as an intensified exterior ground. Red-painted threshold spaces provide another shift in spatial register, marking passages between room, terrace, and circulation. Below, the existing house retains its more accumulated domestic character, including collected masks, antique furniture, colored walls, and sculptural stair elements. The rooftop intervention therefore does not replace the interior life of the older building; it adds a distinct architectural world above it.
About MVRDV
MVRDV is a Rotterdam-based architecture and urbanism practice founded in 1993 by Winy Maas, Jacob van Rijs, and Nathalie de Vries. The practice works across architecture and urbanism, as demonstrated by Didden Village, its first completed project in Rotterdam.
