Integrated trap doors
With an integrated Trap door on top of your Spiral Cellar, you have more freedom to decide whether the cellar should be a major or minor part of the interior. By covering the top of the door with the coating of the remaining floor around the door, you get a fully integrated cellar.
Integrated Trap door are made for tiles and wood cladding and natural stone. The door will be motorized and a gas damper/lifting arm is added to help lift the weight of the door.
The hatch is operated from a switch on the wall with an active up/down push, typically mounted in the same place as the light control.
