This minimalist family home is the architect’s own house—a personal manifesto in which more than two decades of designing residential architecture for others is condensed into a single, highly concentrated response to a demanding urban plot in Prague. Every centimetre became a deliberate decision, resulting in a “minimal maximum”—a house without corridors, organised around a central dining space that rises four metres and connects three floors through a staggered half-level system.
The plot between villas and apartment buildings seemed so impossible to build on that for a long time it remained nothing more than a neglected vacant lot with three rusted-out garages. Just 240 sqm, the immediate proximity of surrounding buildings, a mature cherry tree, and an adjacent train track—this was a challenge for the architect Jan Jakub Tesař in designing a home for his own family. The absolute creative freedom the family offered brought with it a different kind of responsibility: “The plot shaped it, ambition motivated it, and responsibility refined it. I built the house for us, for the whole family, but it reflects my ego. An ego shaped by twenty-five years of learning from the experienced and by building homes for others.”
Setbacks and minimizing shading of neighbours, adherence to the street line, and preserving the mature cherry tree were the constraints that defined the final shape of the building. Although the floor plan covers 70 sqm —and only 49 sqm of those rise to the height of the surrounding buildings and complement the street front—the house does not feel cramped from the outside or the inside. At first glance, it is not obvious that this is a three-bedroom property with a living area of 100 sqm.
The spatial generosity is enhanced by the internal staggered arrangement of the floors—each room occupies a different height, always accessible from the landing of a multi-flight steel staircase. Thanks to this, the house has no hallway, and its heart—the dining room—has a ceiling height of 4.2 meters and receives sunlight from three directions. The adjoining recessed trapezoidal living area is a cozy nook with a library; it is sunken so that its height from the street is as low as possible and it can follow the property line as required by law, with the floor resting on a load-bearing layer determined by the structural engineer.
The offset floor level and partial underground location dictated the choice of material for the load-bearing walls. The concrete remains exposed in its raw state—the designed formwork joints are visible on both the walls and ceilings. Except for two partitions separating the bathrooms, the space is organized by built-in furniture. The grain of walnut wood from a single trunk appears in the entryway, in the living room, on the kitchen cabinet doors and solid sliding doors, as well as on the wall unit by the staircase, softening the rawness of the load-bearing structure. The bedrooms are finished in a neutral white lacquer.
The raw materiality of the interior contrasts with the precise façade. The entire structure, including the gate and part of the fencing, is clad in white profiled aluminium sheet. Vertical ribbing subtly modulates the light and gives the façade a delicate texture rendered by the sun’s rays. The same sheet metal, the same profile, the same white: a gesture that transforms a complex program into a single legible volume. Conversely, a large sliding window in the garden façade opens up the envelope: thanks to it, an entire wall in the dining room is effectively replaced by a view of the garden.
Concrete, which excels at thermal storage, combined with triple-pane windows, controlled ventilation, an air-to-water heat pump, and underfloor heating ensures a perfect indoor climate. A rainwater storage tank is used to irrigate the garden and the green roof. Basic energy needs are met by photovoltaic panels. The building thus has minimal operating costs and is highly energy efficient.
The house is designed as a unique creation down to the last detail, including a custom-designed door handle. This handle follows the same design logic as the entire project. Its precise and functional geometry also serves as an artistic statement.
