Every Pushka mortice knob starts the same way: a pair of solid brass knobs for an internal door. What makes each pair yours is the insert set into the centre. Wood, leather, terrazzo, gloss or Paint Your Own each brings something different to a room, so the real question isn't which knob, it's which room.

Here is how we'd use them, room by room.

The hallway: terrazzo

The hallway sets the tone for the whole house, and it's usually where the hardest-wearing materials are: tiled floors, stone, a runner on the stairs. Terrazzo belongs here. Its flecked, stone-like surface sits naturally beside encaustic tiles and painted woodwork, and it gives the first door you reach a sense of weight and permanence.

The living room: wood

Living rooms are about warmth. A wood insert in oak, walnut or zebrano picks up timber floors, a sideboard or a bookcase and brings it to the door. Oak suits soft whites and pale greys; walnut holds its own against deeper, richer paint colours.

The kitchen: gloss

A kitchen is full of hard, clean lines: cabinetry, worktops, tiles. A gloss colour insert belongs among them. Match it to your cabinet colour for a tailored finish, or pick out a shade from the splashback for a small, deliberate contrast.

The bedroom and study: leather

These are the rooms you retreat to, and they call for something softer. Leather is warm in the hand and quiet to the eye, the same material you'd find on a good chair or a well-made bag. It brings a tailored, slightly club-like feel to a study and a calm finish to a bedroom door.

Children's rooms and playrooms: Paint Your Own

Rooms that change as quickly as the people in them need hardware that can keep up. A Paint Your Own insert arrives primed and ready for your paint, so it can match the walls today and be repainted when the room grows up.

Bringing the house together

The simplest way to make a scheme feel considered is to keep the brass finish the same throughout and let the insert change from room to room. Gold on every door, with terrazzo in the hall, wood in the living room and leather upstairs, reads as one house rather than a collection of rooms.

And because every insert is interchangeable, nothing is fixed. Redecorate, and the insert can change with the room while the solid brass knob stays on the door.

One thing to know: our insert knobs are made for internal doors, cupboards and furniture, not front doors.
