  • Endlich genug Platz für die Werkbank

    Meine Hobby-Tischlerei lief in der Garage immer am Limit. Werkstatt gibt mir die Werkbank, Lagerregale und Bewegungsraum für Plattenmaterial. Stromanschluss habe ich mit Elektriker selbst gemacht.

  • Modellbau mit eigenem Reich

    RC-Modellbau und 3D-Drucker — meine Frau wollte das nicht mehr im Wohnzimmer. Werkstatt ist perfekt: drei Werkbänke, sortenreines Werkzeuglager, gute Belichtung.

  • Verkleidung musste geölt werden

    Fichte unbehandelt heißt: man muss vor Ort streichen. Wir haben Holzöl genommen, das hat zwei Tage gedauert. Sonst alles top. Konstruktion solide, kein Knarren nach einem Jahr.

  • Bastelraum für die Kinder

    Wir wollten einen kreativen Raum für unsere drei Kinder — Werkstatt war der Treffer. Hammer, Säge, Acrylfarben — alles bleibt draußen, das Wohnzimmer bleibt sauber.

    Stefan und Yvonne D. · Essen · February 2026
  • Selbstaufbau über vier Wochenenden

    Tischler-Lehre liegt lange zurück, aber mit der Videoanleitung machbar. Schraubpfähle hat ein NRW-Partner gemacht, alles andere selbst. Die SIP-Paneele sind erstaunlich präzise gefertigt.
