Using a play of diagonal lines and zig-zag geometry, CONTAMINAR Arquitetos architects designed a single-family home in Marinha-Grande, a coastal town in Portugal on the left bank of the River Lis.

The house has an industrial and contemporary image, with a large, black, dynamic metal visor resting on a glass box. The walkway leading to the building is a garden promenade, with two paths, a road, and a pedestrian path that branches off. Natural light plays an important role in the project.
Marinha-Grande House by CONTAMINAR Arquitetos is a home without barriers between the interior and exterior since the vegetation and the courtyard garden invade the interior space. The entrance hall leads to the office access room and a small bathroom. On its opposite side is the kitchen. The corridor joins the social sector with the private one, with a corridor that leads to the rooms of the house.

In relation to the materials used in the project, it is worth highlighting the use of reinforced concrete walls that are combined with large glass openings to obtain the best possible energy efficiency thanks to the passage of natural lighting. The cover is made of metal and stands out by providing a certain character to the house.
 

Description of project by CONTAMINAR Arquitetos

I get in the car, turn the keys, listen to the noisy symphony coming from the engine, and hit the road to reach my house in the town of Amieira, next to Marinha Grande, the land of glass and the mold industry in Portugal.

Arriving at the desired address, after passing through the small family industries and between the pine forest of Leiria and the small town of Amieira, with some isolated and disordered houses, I see amidst the green vegetation, at the bottom of the plot, the house, which has an industrial image, which refers to the industrial pavilions in Marinha Grande, but at the same time conveys the comfort, scale, and image of a contemporary dwelling. A large and voluminous metallic canopy, black and dynamic, draws the contours of the house and rests on a glass box that makes it levitate.

The zigzag path from the entrance gate to the house is a walk through my garden, an alley with two paths, one for the car and another pedestrian that branches with other paths through the garden.

As I approach, I discover the outdoor pool that forms a mirror and a scenographic image in front of the house. I also dazzle a small volume hidden by the plants, the garage, but I continue my way on wheels through the garden that leads me to the main building.

Upon reaching the end of the route, I am greeted by a large porch where I park the car, and in the center of my canopy there’s a welcome patio that is the center of the house, which perforates the large black square covering the house, organizes the “U” shape of the house and separates the social area from the intimate area. The concrete exterior walls contrast with the transparency of the glass and protect the most private spaces.

The patio light gets me to the wooden front door. Upon entering, I feel that there are no boundaries between the outside and the inside, the surrounding greenery, and the courtyard garden invade the interior of the home. The industrial look disappears and I feel the comfort of my home. I leave my coat and car key in the entry hall, on the central piece of furniture, which separates the living room from the access to the office and a small bathroom to support the social area. On the opposite side is the kitchen that extends my gaze over the garden.

I follow the corridor that joins the social area to the rooms and goes around the central patio, maintaining visual contact with my car that rests under the roof, and I pass the laundry room without realizing it. When I enter the corridor of the private volume, where the rooms are located, I am surprised every day by the light from the back of the corridor, coming from the small patio that takes me to my room, as well as, when I enter all of the rooms, the light and the green of the garden again destroys the boundaries between the outside and the inside and lets the big green rug invade the rooms.

Upon entering my room, I go to the closet and bathroom to make myself as comfortable as possible, and later, when I rest my head on the pillow, I will feel that at the end of this trip, life is like a road, my body is the car that travels through it, and my house is the service station that fuels me and supplies me with the energy I need for the next few kilometers.
