Complex composed of the house itself, garage for 2 cars, covered terrace and swimming pool
The concept consists of the intersection of 2 blocks: a higher one, where the bedrooms are on the first floor; and the second shorter one, where the living room is.
The house is located in the northernmost part of the land, with the main entrance facing the street. Thus, the edifice blocks the view of passers-by towards the inner courtyard with the garden and swimming pool.
COR-TEN STEEL
Tatiana Lupascu (architect – concept author): "We wanted to achieve the effect of a cake, 'covered' in white marzipan, from which we could cut and reveal a chocolate sponge! Well, we settled the marzipan part – large-format, matte white porcelain tiles applied on a ventilated façade system. The 'chocolate,' however, was a challenge: we wanted something more exotic, more vibrant. And that’s why we chose COR-TEN!"
Materiality plays a crucial role in the architectural expression of the house. Initially, COR-TEN steel looks like any other steel, but over time, as it is exposed to environmental factors, the rust layer transforms into a thin patina, protecting the surface and making the material corrosion-resistant. Its color evolves from freshly formed orange-brown to lighter brown and, finally, to dark brown.
The main challenge was controlling the oxidation process. On one hand, we wanted to maintain the reddish hue of the COR-TEN steel without reaching its final dark brown stage. On the other hand, since we had a light-colored façade, it was essential to prevent uncontrollable rust runoff staining the white surfaces.
Surface treatments with special solutions could accelerate oxidation in just two hours, but the result did not reproduce the authentic appearance of natural oxidation. After multiple consultations, the façade contractor, Anteco, came up with an ingenious solution: to "trick" nature! The prefabricated panels were laid horizontally in the open air and exposed to environmental factors in a controlled manner until the desired color was achieved. Only then was a protective layer applied to stop the oxidation process, and the panels were mounted on the ventilated façade system.
COR-TEN was also used for the decorative façade elements, shading systems, and vertical sliding louvers, adding dynamism and rhythm to the architectural composition.
In the end, we achieved the desired effect: a striking contrast between the pure white surface and the vivid, metallic texture of COR-TEN, resulting in a distinct and memorable architectural expression.
