When we choose a material, the first thing we ask is how it will look in ten years. Good materials look lived-in by then, poor ones look worn out. That choice is made early in the interior design and stays with the building for as long as it stands.
Search for durable materials and you mostly find product guides: properties, benefits, data sheets. We are more interested in an earlier question: how do you feel about surfaces that change? We build houses from materials that are allowed to age, for clients who intend to stay, as an interior designer in Berlin and on Mallorca alike.
How to tell patina from wear
In a first photograph, wear and patina can look much the same. In fact they are opposites. Wear is what happens when a surface fails: the coating comes away from the board beneath, the edge chips, the wood grain turns out to be printed. From then on it only gets worse.
Patina is what happens when a material gains something through use. Stone picks up a soft sheen where people walk, wood darkens where light and hands reach it, metal loses its factory-new look. None of this is a defect that needs repairing. It simply shows that people live in the room.
Technically the distinction is simple. A material ages well when it is solid, or when its surface is mineral and stays bonded to what lies beneath. It ages badly when a thin, attractive layer sits over a different and less attractive core. A surface that is only perfect on the outside can only lose with time. A material that is the same all the way through can change and still be the same material.
A whole group of materials looks convincing in a showroom and disappoints in a home. We mean build-ups where a thin decorative layer sits on a carrier: foils on cabinet fronts, printed wood grain on boards, coated worktops with a visible edge, veneers too thin ever to be sanded. These are competently made industrial products, and on a tight budget we use them ourselves in certain places.
The difference shows at the first scratch. With a solid material you find the same material underneath. With a layered build-up you find something else, usually a grey or brown carrier board, and from then on the whole surface looks damaged. The same goes for edges that lift, joints that open and printed grain that repeats every few boards.
This is no judgement on manufacturers. It comes down to how a product is built, whatever the brand. A well-made layered product in the right place is better than solid wood in the wrong one. So for every surface we ask: what happens when it gets damaged? Does it then need replacing, or does the mark become one more sign of use among many?
Lime plaster: why we prefer it for walls
When a wall is meant to have character, we usually propose lime plaster. It is mineral and vapour-open, and it can take in moisture and release it again. In damp rooms and in period walls without a damp-proof course, this keeps the wall dry over the long term. Behind a sealed layer, damp problems can build up instead.
Then there is the look. With lime, the pigment is held in the body of the plaster and does not sit on top as a film of paint. Light travels a short way in and comes back softer. A lime-plastered wall looks different in the morning and in the evening, which is why a room finished this way feels calm without feeling empty. A small knock reveals the same material underneath and becomes hard to spot over time. The marks of the trowel stay visible, and that is intended.
Natural stone and Marès for floors, stairs and washbasins
Natural stone is the same all the way through as it is on the surface. A scratch in a stone slab exposes more stone. That makes it the right material for floors, thresholds, stair treads and washbasins, in other words for everything used every day.
On Mallorca, Marès is the stone the island is built from: a warm, sandy limestone, soft enough to be worked by hand, open-pored, in a colour that suits the island's light. It absorbs moisture, weathers on the facade and its edges round off over the years. If you choose Marès, you choose that too. In Berlin we more often use denser limestones and terrazzo, which suit the structure of period buildings and underfloor heating.
The surface finish matters at least as much as the stone itself. Honed, brushed, sandblasted or split-faced: each ages differently. On a high-gloss polished surface every micro-scratch shows up as a dull haze. A brushed or honed surface takes the same wear without it showing. For heavily used floors we therefore nearly always choose the quieter finish.
How solid wood, brass, copper, ceramic, linen and wool age
Solid wood darkens, and we want it to. Oak turns warmer, walnut deeper, cherry noticeably redder. We allow for that change and choose the tone for how it will look in the finished room after some time in the light. The showroom sample does not show that tone yet. We prefer oiled surfaces to closed lacquers: oil soaks in and can be topped up in places, while lacquer forms a film that eventually has to be stripped completely. How we apply this in joinery is set out in Bespoke built-in cabinetry and joinery.
Brass and copper show whether someone really wants patina. Unlacquered brass loses its yellow shine, stays bright where hands hold it and darkens in between. Copper turns brown and later green. There are lacquered versions that stop this process, and they have their place. But a lacquered surface is still a layer, and one day it will be damaged. We raise this explicitly during design, because handles and taps show it more than anything else.
Hand-glazed ceramic is irregular from the first day. No two pieces are the same, the glaze runs differently at the edges, and the surface reflects light unevenly. A wall like this has no pristine new state to lose. The fine crazing that appears in the glaze over the years is part of the material.
Linen and wool age faster than anything else in the room, and they still belong on this list. Linen gets softer with every wash and hangs better. Wool naturally resists dirt and keeps its structure for years. Both fibres lose their early stiffness after the first few weeks and become more pleasant to use. Synthetic covers keep their shape longer, but then they pill, and that cannot be undone.
Berlin and Mallorca: what period buildings and island climate demand
A Berlin period building has its own requirements. The walls are solid, often without a horizontal damp barrier, so they need build-ups that let moisture through instead of trapping it. The heating season is long, indoor air is dry in winter, and solid wood moves noticeably during those months, which determines joint patterns and construction details. The existing fabric has also aged already: floorboards, plaster mouldings, old doors. New material has to sit well next to it without making it look shabby. What we keep and what we replace is described on our page on renovation.
Mallorca has different requirements. Salt in the air attacks metals, even some distance from the sea: untreated steel rusts, some alloys hold up and others do not. Humidity is high and varies a lot between summer and winter, which calls for vapour-open wall build-ups and solid wood with enough room to move. The light is harder and more direct than in Berlin. It bleaches textiles, timber and pigments faster and shows every unevenness in a wall. Lime plaster copes with this better than a flat coat of paint, because its irregular surface scatters the strong light. The material palette that follows from this is shown in Mediterranean kitchens: materials, colours, trends.
How much care these materials need
Letting a material age does not mean neglecting it. It needs care, usually less than owners expect, but of a different kind.
Natural stone needs a sealer that stops oil and wine soaking in, and after that mainly pH-neutral cleaning without acids or abrasives. Oiled timber needs re-oiling more often in the first months and rarely after that, just where it gets the most wear. Lime plaster is dusted dry and never scrubbed wet; small blemishes can be filled with the same material. Unlacquered metals need nothing at all if you want the patina, and an occasional polish if you prefer them bright. You just have to pick one and stick with it.
The difference is one of principle. With a material that is allowed to age, care is local, reversible and a continuation of the building work. With a coated material, care only limits the damage until the surface has to be replaced. That is why these houses cost less over the decades, even though they cost more at the start.
Where patina is welcome and where it is not
We make this decision surface by surface in every project. Not every surface in a house should change. Some definitely should, others should reliably stay as they are, and a room works because of the mix of the two.
Take the kitchen. Cabinet fronts are always in view and are touched all the time. Here we like oiled solid timber fronts or lacquered surfaces that can be repaired, and patina is welcome because it makes the kitchen look lived-in. The worktop is a different matter. Food is cut on it and wine glasses stand on it. Most clients want it to stay reliable, so we choose denser stones or a finish that does not hold marks. If you want patina there too, you can choose open-pored stone, but the first oil stain will stay. The floor carries the footfall of the whole house, and that is where patina looks best, because it develops evenly across a large area.
Our rule: patina belongs on large, continuous surfaces that change evenly, and on things you touch with your hands. Where change appears in isolated spots and reads as a stain, it is out of place. How we settle these decisions during design is part of our interior design work.
The overview below shows how the materials we use most often age, and where in a house they can be allowed to show it.
| Material | How it ages | Where it may show it |
|---|---|---|
| Lime plaster | Takes in light, small blemishes become hard to spot over time, trowel marks stay visible | Walls in living rooms, bedrooms, bathrooms; period walls without a damp course |
| Natural stone and Marès | Footfall marks, soft sheen along walking routes, rounded edges; Marès weathers open-pored | Floors, stairs, thresholds, facades, outdoor steps, washbasins |
| Solid wood, oiled | Darkens, turns warmer in tone, takes on signs of use, can be re-oiled locally | Built-in furniture, kitchen fronts, tables, floorboards, stair treads |
| Brass and copper, unlacquered | Tarnishes dark, stays bright where hands hold it, copper turns brown and green | Handles, hardware, taps, light fittings, exposed edges |
| Hand-glazed ceramic | Irregular from the start; fine crazing in the glaze over time | Kitchen splashbacks, bathrooms, niches, wall surfaces in the light |
| Linen and wool | Soften, hang better, settle; colours become quieter | Curtains, upholstery, cushions, rugs, bed linen |
| Coated and foiled boards | Stay unchanged until the first edge damage, then the carrier core is visible | Joinery out of sight, utility rooms, service zones, where budget comes first |
FAQ
Which materials age beautifully?
Materials that are the same all the way through as they are on the surface: natural stone, solid wood, mineral lime plaster, unlacquered metals such as brass and copper, hand-glazed ceramic, linen and wool. When they are damaged, the same material shows underneath, so the mark blends into the surface. Build-ups with a thin decorative layer on a carrier of a different colour age badly, because every bit of damage stays visible.
Is lime plaster suitable for living rooms?
Yes, and it is often the first thing we suggest there. It is vapour-open, taking in moisture and releasing it again, which helps in bathrooms, kitchens and period walls without a horizontal damp barrier. It also looks deeper than a flat coat of paint, because light travels a short way into it. What matters is a proper build-up on a suitable substrate and a specification that suits how hard the room is used.
How do you care for natural stone indoors?
Seal it first so that oil, wine and coffee do not soak in, and repeat the sealing depending on how heavily it is used. After that, cleaning with pH-neutral products is enough. Acidic cleaners and vinegar attack stones that contain lime and dull the surface, and abrasives scratch it. Lift spills instead of wiping them across the stone. A brushed or honed finish copes with everyday life better than a polished one anyway.
What is the difference between patina and wear?
Patina is a change that belongs to the material and makes it more interesting: darkened wood, stone with a soft sheen where people walk, brass that has tarnished. Wear is a failure of the surface that exposes something that was never meant to be seen: a lifted edge, a decor rubbed through, a split coating. Patina improves over the years, wear only gets worse. Which one you get is decided when you choose the material, and maintenance can change little after that.
