Clarity in an Industrial Context: TopHaus Spini

Clarity in an Industrial Context: TopHaus Spini – Architecture by DEAR Architects
Interview with Lorenzo Scacchetti, Architect at DEAR studio

TopHaus is one of the leading suppliers of building materials and DIY products in South Tyrol and Trentino, with locations in Bolzano, Bressanone, Lana, Rasun, Lavis, Pergine Valsugana, and Trento.

The new headquarters of TopHaus has been established in Spini di Gardolo, covering a total area of approximately 20,000 m², with a main building of 3,000 m² across three levels and a warehouse of over 7,000 m². The ground-floor retail space is already operational.

We spoke with Lorenzo Scacchetti, architect at DEAR studio, about the architectural concept, the role of the façade, BIM design, and the distinctive features of the project.

What architectural and functional elements define the TopHaus Spini concept?

The project is located within a typical industrial context, lacking significant architectural references. The initial idea was therefore to create a clean, rigorous building based on regularity and geometry, deliberately avoiding expressive or decorative elements beyond the structure itself.

From this approach emerged a form that highlights the use of prefabricated concrete elements, giving them architectural quality. The façade is inspired by the classical post-and-lintel principle, reinterpreted in a contemporary key through the use of prefabricated elements supplied by Progress AG. A constant and regular rhythm, consistently applied across all façades, defines the building’s identity.

While the main entrance and the café feature full-height openings, enhancing the direct connection between interior and exterior, the retail space required some solid walls for product displays. The ground floor therefore expresses clear permeability at the entrances, while the sales areas take on a more introspective character, with openings placed at a higher level. The result is a balance between open and closed surfaces, creating spaces that are functional yet bright, alongside more inviting, intimate areas.

How is the integration between the retail space and the “Sosi Café” achieved?

The café also faces the façade. The connection between the two spaces is a window in the dividing wall, designed as a communication element between the areas. Customers and café guests can see each other, creating a dynamic atmosphere that makes the café a meeting point for both visitors and staff. The space functions not as an isolated entity but as an integral part of the building.

How does the façade concept influence natural lighting in the store?

In the retail area, where shelves are installed, full-height windows would have interfered with product display. Openings were therefore placed in the upper part of the façade. This allows the space to be naturally illuminated while maintaining continuous wall surfaces for shelving. Finding the right balance between lighting and functional display was a central design challenge.

The project was fully developed in BIM using Progress prefabricated elements. What advantages did this approach offer?

We use BIM (Building Information Modeling) on all our projects. Compared to traditional 2D design, the 3D model allows integration of a much larger amount of information.

For TopHaus Spini, the process was particularly efficient: the 3D model was cloud-based, shared in real time among architects, structural engineers, MEP consultants, and Progress as the prefabrication manufacturer. This enabled early detection of clashes between disciplines and immediate verification of design solutions within the model.

Were there any critical aspects to manage?

Coordination between architectural design, structural elements, and MEP systems is where BIM shows its full potential. In the 3D model, it is immediately visible if, for example, a structurally loaded area conflicts with MEP routes. This allows issues to be resolved before construction begins.

Another advantage relates to production: prefabricated elements were manufactured directly from the 3D model, including all structural and MEP provisions. Progress was able to transfer the data straight to production, eliminating the need for additional drawings and ensuring precise clash control.

A distinctive feature is the green rooftop terrace. What role does it play in an industrial context?

The site is dominated by industrial buildings, concrete, and limited greenery. The terrace therefore represents an ecological and spatial counterpoint. A green surface has been installed on the roof, bordered by shrubs visible from the street.

This space provides employees with an area for relaxation and regeneration while also serving a functional purpose: TopHaus can use it to display products. It is a place that combines spatial quality with operational utility within an industrial context.

The construction was completed in just 12 months. What made this timeline possible?

BIM significantly reduces the number of steps and checks. Having all information consolidated in a single model allowed direct transfer to the prefabrication manufacturer. MEP systems were already integrated into the structural elements and slabs, drastically reducing on-site issues and enabling a faster construction timeline. For a building of this size and complexity, completing it in 12 months is remarkable.

What is the current status of the project?

The structure is complete. The ground floor, including the store and café, is finished and operational.

On the first floor, final interior works are underway, housing offices, a cafeteria, the Progress office, and a showroom. Completion is expected by April 2026, when TopHaus Spini will be fully operational.

The project demonstrates effective collaboration between TopHaus, Progress, and DEAR studio through the use of contemporary design methods.
