Interior design for a country house: why the project is more complex than an apartment

In an apartment, half the decisions are already made for you: heating, ventilation, water, the boundaries of the walls, even the ceiling height come from the building. In a country house, nothing is decided yet — and that's the main difference all the others follow from.

Engineering: given in an apartment, designed from scratch in a house

This is the most underrated difference. In an apartment, a designer works with fixed points: the riser is here, the radiator is under the window, extraction is already in the kitchen and the bathroom, the electrics are already wired in. In a house, all of this has to be designed.

Rooms appear that don't exist in an apartment at all: a boiler room or plant room, a water-treatment unit, space for manifolds. Decisions appear that can't be put off: the type of heating, whether supply ventilation includes heat recovery, the reserve of electrical capacity, the drainage layout. Each of these takes up space and affects the layout — a boiler room doesn't just go wherever there's room left; it has its own requirements for area, access and ventilation.

The practical consequence: a house's interior can't be designed in isolation from the engineering sections. Either the same designer handles both, or the two need to be constantly checked against each other.

The staircase isn't a detail, it's an object in its own right

Apartments rarely have more than one level. In a house, the staircase determines the layout of both floors at once: its position sets where the halls end up, how much floor area goes to circulation, and how the bathrooms are distributed.

The most common mistake is a staircase designed by the builder “on the spot”, before the interior even exists. The flight ends up technically sound but compositionally accidental: it runs into a wall, blocks light from a window, or lands right in the middle of what's meant to be the living room.

A second floor also adds things you'd never think about in an apartment: sound insulation between floors, and a separate bathroom upstairs. A night-time trip down the stairs to the only bathroom, on the ground floor, is exactly the kind of thing that only shows up once people are actually living there.

A house is tied to its plot, an apartment isn't

An apartment's windows look out onto the city, and the view rarely plays a part in the project. In a house, orientation to the compass points and the view from every window are starting data, on a par with the floor area.

That leads to decisions an apartment never requires: where panoramic glazing is justified, and where it will turn a room into a greenhouse by July; which way the terrace faces and whether it works outside the summer months; how the entrance is organised — a vestibule, a boot-room zone, somewhere for wet footwear.

The seasons themselves change how materials are chosen. A house lives through a wider range of temperature and humidity than an apartment, and some rooms may not be heated at all in winter.

Utility rooms that an apartment doesn't have

In an apartment, the utility function shrinks down to a cupboard and a niche for the washing machine. In a house it expands back out: a laundry and drying room, a pantry, space for garden tools, storage for seasonal items, sometimes a separate entrance for the utility zone.

This is the first thing cut to free up impressive floor area, and the first thing people regret. Without a utility block, its functions migrate into the main rooms — and within a year the living room stops looking like the visualisation.

Light in a house is designed twice over

In an apartment, natural light is a given: the windows are wherever the developer put them, and the only question is how to arrange the furniture around them. In a house, the windows are designed, and along with them, how much light each room gets, hour by hour.

That leads to decisions an apartment never raises. It makes sense not to face the kitchen south-west if the family spends evenings there: in summer that's the hottest spot in the house. A bedroom, on the other hand, is worth orienting so the morning sun arrives exactly where it's wanted. Panoramic glazing on a south-facing wall, without external shading or solar-control glass, turns a living room into a greenhouse — and the fix later on is curtains, which means giving up the very view the window was built for.

Artificial light is more complex in a house too. High ceilings and double-height spaces can't be lit by a single chandelier; the staircase needs its own scenario and switching from two points as standard; the terrace and the driveway need outdoor fixtures on their own circuit. A house's lighting layout is almost always a multi-scenario one, and it has to be planned before the finishing works, together with the electrics.

Materials behave differently

A timber-frame or log house settles, and the finishing has to allow for it: sliding joints, expansion gaps, avoiding rigid continuous solutions in the first few seasons. Even in a masonry house, the swing in humidity between the heated and unheated periods is greater than in an apartment.

This isn't a ban on demanding materials, it's a requirement on the details. The same parquet is laid differently in a house than it would be on the tenth floor of an apartment block.

When to start the project

Earlier than for an apartment. The ideal moment is once the shell is up but the engineering hasn't been routed yet. That way sockets, switches, underfloor heating, extraction, niches and fixings for furniture are placed according to the project, rather than wherever happens to fit afterwards.

If the interior design starts after the finishing work, some decisions are already off the table: you can chase fresh walls, move radiators and add light points, but that's rework, not design. In an apartment the cost of that delay is lower, because the engineering was already fixed anyway.

How much it costs

A house project is priced by floor area, just like an apartment, but at a higher rate: the same square metre carries more detailing, more engineering, and more coordination with other designers. For us that's from €60/m², from €90/m² or from €120/m² per square metre, depending on the package — more detail on the house and villa interior design page.

The difference from an apartment isn't just in the rate, but in the timeline: there are more approvals, and some of them depend not on the client but on how ready the adjacent sections are.

What this means in practice

A house gives you more freedom and fewer cues. In an apartment the layout is largely dictated by the structure and the risers — there aren't many of them, but they set the frame. In a house you have to build that frame yourself, and a mistake in it doesn't show up until people have actually moved in.

That's why a house project is worth starting with questions an apartment never raises: how the entrance works in winter, where the washing dries, where the sun falls at six in the evening, what's visible from the bedroom window. The answers shape the layout more than the style does.
