Architecture for homes,schools and workplacesin Central Europe.

Halde is a practice of twelve architects in Bratislava. We design new buildings and careful extensions for families, towns and developers, from the first site walk to the last snag list.

How a building comes together

Four stages, one team. The architect who draws your building on the first day is the one standing next to you at handover.

  1. Sunlight and shadow dividing a concrete wall
    01 — GroundWeeks 1–3

    We start on the site, not on a screen.

    Before any drawing, we spend a full day on your plot: where the sun falls at nine and at four, where water runs after rain, which trees must stay. The brief is written there, with you.

  2. White architectural model with tiny trees and figures
    02 — ModelWeeks 4–10

    Every scheme is tested as a physical model.

    We build two or three massing models at 1:200 and put them on the table between us. It is the quickest way for anyone, not only architects, to see what a building will do to its street.

  3. Concrete stair seen from above
    03 — DetailMonths 3–9

    Drawings a builder can actually price.

    Permit and construction drawings are made in-house, joint by joint. Every contractor bids on the same complete set, which keeps quotes close together and surprises on site rare.

  4. Afternoon shadows of leaves on a wall above a bench
    04 — StayHandover + 12 months

    We come back after a year.

    During construction we are on site every week. Twelve months after you move in, we return to see how the building lives through the seasons, and we fix what we got wrong.

Twelve people, one long table, and no site we haven't walked.
