U-raw: the prefabricated construction system of standardised elements designed by Viraje

U-raw is an innovative construction system based on industrialisation. We combine standardised prefabricated elements to achieve a more sustainable, affordable, and quick-to-implement architecture.

This system was created to respond to the new vital needs that converge in the home, including professional, family, social, and leisure activities. These activities require a more adaptable space and a contemporary architectural solution. We propose a flexible and standardised system capable of adapting to future situations.

Thanks to the industrialisation and technification of the processes, we have reduced on-site waste by 73% compared to traditional construction. In this way, U-raw responds to a model of efficient and sustainable construction and claims the system’s expressive potential, where industrialisation is not a limit but an opportunity to create spaces with a unique identity.

UR03: A project designed and executed entirely using the U-raw system.

Located on a plot of elongated proportions in La Cañada (Valencia), this family house has been designed to dialogue with the geometry of the terrain, developed on a single-storey to optimise its integration into the surroundings. The project has been developed entirely with the U-raw system with a surface space of a hundred and seventy-four square metres.

Combining wood, concrete, and glass defines the sought-after aesthetic, creating a balance between solidity, warmth, and transparency. The materiality is left visible, raw, and pure, showing off the ‘raw’ essence. This is a dry construction that, in turn, favours sustainability in the construction process.

The design of this house is structured around two longitudinal spaces that form the public and private areas functionally and fluidly. The public area integrates the living room, dining room and kitchen in a promenade that starts from the main entrance and culminates in the connection with the exterior. The transition between areas is materialised in a wooden envelope in soft acacia tones, where partitioning, panelling and furniture merge into an internal façade that separates the public from the private without the need for corridors or unnecessary circulations.

The structural rhythm marked by the prefabricated beams emphasises the organisation of the spaces without fragmenting them, allowing a continuous perception of the dwelling. The trowelled concrete floor reinforces this spatial continuity, eliminating visual divisions that interrupt the appreciation of the project’s longitudinal perspective.
