CASE STUDY 04

Custom Furniture

Furniture designed and built for spaces that aren’t working. From concept sketches to Blender prototypes to fabrication — across wood, concrete, MDF, steel, and leather.

Every piece here started with a constraint: a narrow hallway, a rental kitchen, a Plattenbau apartment that needed to feel like one space. The furniture is the solution.

Design for permanence,not for deadlines.

Every material decision in this work starts from the same question: will this still be right in twenty years? Not fashionable, right. The apartment runs on a minimal material palette: unsealed concrete floors, MDF finished with shellac and wax rather than paint, steel frames, leather details. Nothing is introduced casually. A new material has to earn its place. 

The pieces below span clients and spaces, built and unbuilt. What connects them is the same approach: understand the constraint first, then design the object that solves it without creating new problems.

A narrow hallway needed a full-height door to the ceiling. A solid door of that scale would have closed the space off entirely, visually and spatially. The bathroom behind it needed light. And the wall beside the door was dead space.

A narrow hallway needed a full-height door to the ceiling. A solid door of that scale would have closed the space off entirely, visually and spatially. The bathroom behind it needed light. And the wall beside the door was dead space.

The door and the adjacent wall are built identically with a 2cm steel frame clad in MDF and lacquered, so the door disappears into the wall when closed. The upper section is plexiglass, chosen over glass for safety, which borrows light from the bathroom into the hallway. On the back face of the door, invisible when closed, a narrow cupboard holds dish towels with a small door of its own. At the top, a recessed space for a planter: a plant hangs down and becomes part of the door’s front face. One object solving four problems simultaneously.

Closed, the door reads as part of the wall. The plexiglass panel transfers light from the bathroom into the hallway. The back face of the door: a cupboard for dish towels, closed off with its own small door. Functional space recovered from what would have been a dead wall.

A Plattenbau apartment with two separate rooms that felt disconnected. Storage was needed in both. Hanging clothes require a minimum of 60cm depth; most of the apartment walls couldn’t accommodate that. The closet had to feel like one continuous element, not two separate pieces of furniture.

A Plattenbau apartment with two separate rooms that felt disconnected. Storage was needed in both. Hanging clothes require a minimum of 60cm depth; most of the apartment walls couldn’t accommodate that. The closet had to feel like one continuous element, not two separate pieces of furniture.

The closet is built through the wall between the two rooms, with books and office storage on the living room side and clothes on the bedroom side. Most of it is 40cm deep. Where hanging clothes require 60cm, the closet widens. A mirror is placed at the transition point so the eye reads the full run as continuous. The finish is MDF stained and treated with five coats of shellac, then waxed and buffed with ultra-fine steel wool. It was a process developed over two months of trial and error. The goal was a material that wasn’t paint, that had depth and could be resurfaced. The result is semi-matte, slightly warm, and closer to a fine woodwork finish than anything you can buy off a shelf.

A rental apartment in a listed Henzelman building with original tiles partially intact and a dishwasher and oven already in place that couldn’t be moved. The kitchen had to work around fixed appliances with awkward measurements, respect the building’s existing material language, and not permanently alter the space since the client didn’t own it.

The kitchen had to work around fixed appliances with awkward measurements, respect the building’s existing material language, and not permanently alter the space since the client didn’t own it.

IKEA carcasses were used as the structural base: practical, removable, rental-appropriate. The fronts are custom-made MDF, designed to read as a coherent whole rather than as modified flat-pack. The colour was matched directly to the client’s work: she is an artist working with natural dyes, and a piece of her dyed fabric was taken to a paint supplier to have the exact colour replicated. The kitchen carries her practice into the space it lives in. An awkward leftover gap between units became a dedicated dish towel hanging area, a detail that solves a small problem but also shows the same attention to the wall that went into the rest of the design.

A bedroom system that solved storage, lighting, and surface access in a single integrated piece, without the hygiene and maintenance problems of fabric headboards, and without the coldness of purely hard surfaces.

A bedroom system that solved storage, lighting, and surface access in a single integrated piece, without the hygiene and maintenance problems of fabric headboards, and without the coldness of purely hard surfaces.

The headboard is MDF clad in calf hide, the material used by Italian leather goods makers, chosen because it reads as soft without being fabric. Fabric headboards collect dust and are difficult to clean; hard surfaces are hygienic but unwelcoming. Calf hide solves both. The two hanging nightstand boxes are concrete, cantilevered from the headboard structure. Each box has two access points: a drawer that opens toward the bed for everyday items, and an opening from below for things that need to be stored out of sight. Behind the headboard, a shelf with integrated power points and a downlight that washes the nightstand surfaces. The entire system reads as one object from the front. The client relocated before fabrication began.

Three-quarter views and the lighting detail. The under-shelf light is built into the structure, not added afterward as a separate fitting.

The mirror door, when open, would hit the polished concrete floor. A standard rubber door stopper would introduce a material that didn’t belong in the space.

The mirror door, when open, would hit the polished concrete floor. A standard rubber door stopper would introduce a material that didn’t belong in the space.

A small block of beech wrapped in leather, matching the colour and texture family of the other leather details in the apartment. It stops the door, protects the concrete, and disappears into the material language of the space. The apartment runs on a strict material palette. Every detail, down to the smallest fixing, is either part of that palette or hidden. Introducing a cheap rubber stopper would have been a small but visible failure of consistency. The leather block cost almost nothing to make and looks like it was always meant to be there.
