Plan the cat room, climbing routes, resting points and views in relation to human spaces, alongside materials and details suitable for the cats' safe use.

Highlights include a glazed cat room connected to the shared spaces, double-height living and vertical areas where the cats can climb, play and remain visually connected with the household.

It can suit a separate enclosed dressing room, making clothes visible and easy to reach. An organised storage system should be planned from the outset.
