Casa do Alpendre Is the Portuguese House That Turns Privacy Into a Floor Plan
Casa do Alpendre sits on a plot in Quinta da Coutada, Vila Franca de Xira, where no two buildings speak the same architectural language. Vasco Burnay Arquitectura had a blank canvas and a difficult neighbor: an industrial facility with sprawling metal roofs right behind the site. Most architects would fight that context. Burnay’s team did something smarter. They built a house that simply turns its back on the problem and faces the sun instead.
I have spent the last few weeks studying this project in detail, tracing every plan, section, and photograph by Ivo Tavares. What emerged is not just another well-photographed house. It is a working case study in what I now call Defensive Domesticity: the design strategy of using geometry, not walls, to protect a home’s emotional core from an unfriendly site. This article breaks down exactly how that strategy plays out, room by room, decision by decision.
Casa do Alpendre in Vila Franca de Xira, Portugal by Vasco Burnay ArquitecturaWhat Makes Casa do Alpendre Different From a Typical Portuguese L-Shaped House?
L-shaped houses are common throughout Portugal. Most use the form for one reason: to wrap a courtyard. Casa do Alpendre uses the L-shape for three reasons at once, and that layering is what separates it from the typical suburban version.
First, the L-shape builds a street-facing volume that fits the scale of the subdivision. It does not announce the full size of the house from the road. Second, the longer wing blocks northern exposure, which keeps cold air and harsh light away from the social rooms. Third, that same wing lets the house “turn its back” on the industrial complex to the north, without needing a tall perimeter wall to do it.
I call this approach Orientation as Camouflage: using the angle of a building, rather than its materials or color, to hide scale and redirect attention. The house does not disguise itself through finishes. It disguises itself through geometry. That is a meaningfully different design tool, and one most residential architects underuse.
The L-Shape as a Privacy Engine
Here is the part that impressed me most. The L-shaped layout places bedrooms to the east and living spaces to the south and west. That split is not arbitrary. It creates a sheltered outdoor zone in the crook of the L, one that catches sun for most of the day while staying invisible from the street and the industrial site alike.
This sheltered zone becomes what I call the Privacy Nucleus: a single outdoor space that absorbs every function a family actually uses daily, dining, lounging, and swimming—without exposing any of it to neighbors. Most houses split these functions across a front yard, a side patio, and a back deck. Casa do Alpendre consolidates them into one protected zone. That consolidation is the real innovation here, more than the roofline or the materials.
How Does the Continuous Porch Function as More Than a Walkway?
The house takes its name from the alpendre, the porch that runs along the entire south-facing length of the longer wing. Calling it a porch undersells what it actually does. This element performs three separate jobs: it shelters the interior from direct summer sun, it connects every room along that wing without forcing residents back indoors, and it physically defines the edge of the Privacy Nucleus.
I think of this as Threshold Architecture: a design approach where the boundary between inside and outside is treated as usable square footage, not as a line on a drawing. The porch is not a buffer zone you pass through. It is a room with no walls, used for living, not just for transit.
On the opposite side of the plot, a ramp follows the natural slope of the terrain. This ramp ties together different exterior levels, and it does so without stairs, without retaining walls that break the sightline, and without disrupting the quiet logic of the rest of the site. It is a small move. It also says a lot about how carefully this project treats the ground itself as a material to be shaped, not just built on top of.
Why the Porch Changes How You Use a Pitched Roof
Pitched roofs usually mean wasted attic space or an awkward upper floor. Casa do Alpendre turns both pitched roofs, one over each volume, into genuine habitable attics. The porch supports this by keeping the lower floor open and column-free, so the roof structure above can do more interesting work.
This is where the house earns its second framework, what I call Volumetric Generosity: designing a roof void specifically to add livable height and atmosphere, rather than treating it as leftover structural space. The living room and kitchen sit beneath this void with zero visual barriers between them. You feel the height before you notice the function.
How Is the Program Organized Inside This House?
The house splits cleanly into social and private zones, and each zone gets its own volume. The longer wing holds the social areas. The shorter wing holds the private quarters. This is not a new idea in residential architecture, but the execution here is unusually disciplined.
In the longer volume, the living room and kitchen share one continuous space under the roof void, with no visual barriers. In the shorter volume, four bedrooms sit perpendicular to the main axis, each with its own en-suite bathroom. Two of those bedrooms share a walk-in closet, a detail that signals real attention to how families actually move through a home in the morning.
The Hinge Point Between the Two Volumes
Where the two volumes meet, you find the circulation halls, a pantry, a guest bathroom, and the staircase leading to the attic above the main social volume. I call this junction the Hinge Zone: the compressed transitional space that absorbs all the logistical functions a house needs but does not want on display. Every house has one. Few handle it this efficiently.
The attic above the smaller, private volume is reached through the bedroom at the end of that wing. A custom timber staircase doubles as a wardrobe and bookshelf, which means storage is built into circulation rather than bolted on afterward. At roof level above this section, a technical terrace holds the mechanical equipment the house needs to run, kept out of sight and out of mind.
What Role Does the Exterior Layout Play in the Overall Strategy?
Outside, beneath the continuation of the main volume’s pitched roof, you will find the laundry room and an additional bathroom. This placement matters more than it sounds. It keeps service functions connected to the house without requiring them to interrupt the clean geometry of the social wing.
Moving up the site, an elevated platform holds the swimming pool, positioned to catch the same southern light that defines the rest of the home. At the lowest point, closest to the street, a forecourt provides parking for three vehicles. This sequencing—parking low, living spaces protected behind the L, pool elevated and sun-facing—creates what I call a Gradient of Privacy: a site plan where the most public function sits closest to the street and the most personal functions sit furthest from it, with no fences required to enforce the hierarchy.
Why This Site Strategy Matters Beyond This One House
Most suburban plots in subdivisions like Quinta da Coutada inherit a fragmented context. Neighboring buildings rarely share a language, and proximity to industrial infrastructure is common across Europe’s edge-of-town development patterns. Casa do Alpendre offers a transferable lesson: you do not need to match your neighbors or hide behind walls to claim privacy. You need a plan that does the work for you.
I expect this gradient of privacy approach to show up more often as architects respond to messy suburban infill sites across Portugal and Spain. Land is rarely clean anymore. Strategy has to fill the gap that context used to provide.
Frequently Asked Questions
Who designed Casa do Alpendre?
Vasco Burnay Arquitectura designed Casa do Alpendre, with Vasco Burnay serving as lead architect. The house is located in Quinta da Coutada, Vila Franca de Xira, Portugal, and was completed in 2024.
Why is the house called Casa do Alpendre?
The name translates to “Porch House,” referring to the continuous south-facing porch that runs along the longer wing. This porch shelters the interior, connects the rooms, and defines the edge of the home’s protected outdoor space.
How does the L-shaped layout protect the house from its surroundings?
The L-shape creates a street frontage that hides the full scale of the house, while the longer wing blocks northern exposure and turns the home’s social spaces away from a nearby industrial facility and toward the south.
How many bedrooms does Casa do Alpendre have?
The house has four bedrooms, each with its own en-suite bathroom. Two of the bedrooms share a walk-in closet, and one bedroom provides access to a habitable attic via a custom timber staircase.
What is the total area of Casa do Alpendre?
Casa do Alpendre measures approximately 250 square meters, or about 2,691 square feet, across its social and private volumes plus the habitable attic spaces.
Who photographed Casa do Alpendre?
Ivo Tavares Studio photographed the completed house, documenting the porch, the interior roof voids, the bedroom wing, and the surrounding landscape designed by Jardim Digital.
