Permeability is one of those words architects love to throw around until it starts to lose meaning. But some would argue that behind the jargon lies a fairly practical idea. When it comes to buildings (and façades in particular), permeability is about control. Perforated surfaces decide how much light enters a space, how air moves through it, and how connected a building feels without fully opening itself up. In a way, they offer shade privacy without isolation and comfort without heavy enclosure.

From brick screens and ceramic blocks to metal panels and concrete lattices, this collection offers a glimpse (or a filtered glimpse, if you will) into projects that use porosity with intention. Across climates and programs, their façades show how small openings can shape atmosphere, performance and everyday experience.

Upper Albert

By SAOTA, Cape Town, South Africa

Designed by architect Philip Olmesdahl for his own family, this house embraces a distinct willingness to test ideas without overexplaining them. Set on a steep city bowl site, the home rises above a solid podium to capture light and views. Its most defining feature is the angled concrete screen wrapping the upper levels.

Cast in red-pigmented concrete and mounted on steel frames, the perforated panels provide shade and privacy while giving the façade texture and depth. Reused terracotta blocks from the original boundary wall are woven into the screen, tying memory to structure. The result feels tactile and expressive, where light, shadow and material quietly shape everyday life.

Cantines Zinder

By ACTA – Action through architecture, Niger

Developed in collaboration with GIZ, Cantines Zinder is organized around a single, protected core: a secure room for grain storage. From this center, the building unfolds outward in measured layers, guiding how food is prepared, shared and safeguarded throughout the day. Circulation spaces act as buffers, tempering the climate while quietly directing movement between the kitchen and the dining space, which can shift into a classroom when needed.

Perforated masonry walls form the building’s outer edge, allowing air and light to pass through while keeping the interior shielded from heat and dust. The openings cast soft, shifting patterns across the interior surfaces, making the space feel active without excess. Above, a broad cantilevered roof hovers over the structure, extending shade in all directions and protecting the brickwork below. The gap between the roof and the wall encourages natural ventilation, letting warm air escape as cooler air circulates through the perforations.

REZI HOTEL IN VLORE

By Davide Macullo Architects, Vlorë, Albania

Conceived as a reflection on the human condition, Rezi Dream-Hotel approaches architecture as an emotional and ethical framework rather than a visual statement. Set within a park and read as a quiet citadel, the hotel uses locally sourced materials in muted tones, grounding the architecture in its terrain and allowing it to recede into the Albanian coastline.

Perforated façade elements filter light and views, softening the boundary between interior and landscape while avoiding any sense of enclosure. These screens temper the coastal climate and create shifting patterns that change throughout the day, reinforcing a calm, contemplative atmosphere.

Nothing Design Co. Headquarters

By Range Design & Architecture, Chicago, Illinois

This project expands an existing building into a workspace and showroom for making and displaying furniture. Because the new volume rises along the property line, daylight enters primarily from the street and the yard. A perforated brick screen addresses this constraint on the south-facing façade. Made from terra-cotta — colored pavers, it filters sunlight, reducing heat gain while giving the building a distinct street presence rooted in Chicago’s brick tradition.

On the yard side, a similar screen in common brick defines a second-floor patio, extending the interior outward. Reclaimed and new brick anchor the building in place, using perforation not only to shape light and climate, but also to project a unique visual identity.

Ardete Headquarters

By Studio Ardete, Sahibzada Ajit Singh Nagar, India

When two architects design their office, the expectations are skyrocketing. But, instead of giving in to the surrounding noise, they chose to take the introspection route for developing the space program. At its core, the Studio Ardete HQ is a manifestation of their belief in people-driven spaces. The office was designed around the idea of vertical zoning, where the lower two floors were meant for clients and the upper two storeys were curated for the team.

A key architectural gesture appears on the façade, where a perforated screen made from Meta Sequin coins draws inspiration from the movement of nearby tree leaves. Set at varied angles, the metal elements filter sunlight and soften glare while giving the building a sense of motion. The screen also supports thermal comfort, reducing heat gain throughout the day.

Lake House

By dayala e rafael arquitetos associados, Alexânia, Brazil

From the very beginning, this project clearly signals its close relationship with the landscape. Steel structure allows the house to stretch outward in long cantilevers, opening views toward Lake Corumbá IV while keeping the terrain largely untouched. A façade of spaced ceramic bricks sits in front of glass, catching the sun and breaking it into softer light. The perforated surface adds texture and shade without closing the house off. Inside, wood-lined ceilings temper the steel frame, while large openings keep the lake present throughout daily life.

Evacuation staircase in the Teresianas Ganduxer protected site

By PichArchitects, Barcelona, Spain

Evacuation spaces are usually treated as a last resort, hidden away and stripped of character. The design at Teresianas Ganduxer, however, does the opposite. Inserted beside a historic complex that includes a pavilion by Antoni Gaudí, the new staircase was designed with care, restraint and a touch of generosity.

Placed on the exterior of the Santa Teresa Pavilion, it follows the existing façade rhythm and connects naturally to an internal corridor. A ceramic lattice wraps the stair, its perforations allowing the original building to remain visible behind it. Light and shadow animate the enclosure throughout the day, making the staircase feel considered rather than secondary, while quietly meeting safety needs and restoring value to a neglected corner of the site.
