Custom precast slab edge solution in Llanes, Asturias
In a contemporary residential development in Llanes, Asturias, ULMA Architectural Solutions developed a custom precast slab edge solution designed to integrate seamlessly into the building envelope while meeting the project’s architectural requirements.
Designed by architecture firm Gonzalo Merino Álvarez (Grupo Torre Arquitectura), the project required a slab edge element with a specific geometry and a colour finish precisely matched to the facade design.
A tailored solution for a demanding architectural design
To meet these requirements, ULMA developed a bespoke precast element that not only resolves the slab edge technically, but also becomes an integral architectural feature within the facade composition.
The solution was fully customized to the project geometry, ensuring clean lines and a cohesive visual integration across the building envelope.

Performance and aesthetics in a single element
One of the most distinctive aspects of the project is the dual function of the installed element:
- Efficient technical resolution of the slab edge
- Added architectural value through its visual integration into the facade
The custom RAL 7040 grey finish reinforces this integration, bringing continuity and elegance to the overall facade design.

Custom precast solutions for architecture
This project demonstrates how tailored precast solutions can respond to the specific demands of contemporary architectural design, particularly when standard systems are not sufficient.
The ability to adapt geometry, finishes and detailing makes ULMA Architectural Solutions’ precast systems a valuable resource for architects seeking both technical performance and design flexibility.
