The façade of the house features exposed concrete, contrasting with the surrounding landscaping. For the interior, the design combines white walls, gray granite, aluminum frames, and wooden ceilings. With abundant nature and a privileged view of the valley, the house is elevated 4 meters above street level. Its main façade faces north, and social access is provided via a large 65-meter zigzagging ramp in exposed concrete, which spans the entire front setback of the lot.

​

This ramp serves as a decompressing element, inviting visitors into the atmosphere the house creates. The structure is defined by six large arches, meticulously designed to support the expansive gallery that flows through the social and leisure areas of the residence. The ground-level plateau is raised above the sidewalk, and at the entrance, a single-thickness ramp rests on circular pillars. This architectural feature not only resolves structural challenges but also adds an aesthetic elegance reminiscent of a bird in flight. The house’s slab is lightweight and evokes an oriental architectural reference.

​

During the foundation work, a natural stone wall was discovered at the rear of the lot—a surprising revelation, as this geological feature had not been accounted for in the original soil survey. The wall measures 2.5 meters in height and 25 meters in length. Initially, there was debate over whether to remove it. However, as the concept matured, the decision was made to retain the stone (which is strikingly beautiful) and incorporate it as a sculptural element of the residence. Additionally, the water seeping from the stone creates a unique and surprising ambiance.

The tiled panel was designed exclusively by artist Iêda Jardim to fulfill the owner’s request and enhance the space’s character. Keeping the stone required numerous adaptations to the project. The leisure and service areas were relocated to take advantage of this natural feature. One of the originally planned bedrooms was moved to a location above the stone, transforming it into the standout feature of the house: a space fully integrated with the surrounding nature.

​

The garden design was developed to naturally integrate architecture and landscaping, leveraging the local terrain and enhancing existing natural elements such as large trees, rocks, and light incidence.

​

The private quarters are situated in the lower block, where each bedroom has its own private garden, creating a natural screen for the residents. The service and leisure areas are connected at the rear, near the outdoor area where the stone wall is located. In the arched gallery housing the living room, kitchen, and veranda, the double-height ceiling enhances the space, with floor-level lighting creating playful light and shadow effects on the slab. Large windows facing internal gardens allow generous natural light to permeate without compromising user privacy.

In the master bathroom of Casa Joy, the design ensures favorable natural light distribution. All spaces are airy and integrated with the outdoors. Comfort is achieved through landscaping and natural vegetation, complemented by curtains, wooden ceilings, and frames that provide a thermal barrier.
