What we doThree ways
Three ways
we are asked in
Small hotels
Under twenty rooms, where every room can keep its own plan. We do the rooms, the corridors and the one place people actually sit in the lobby.
From €45,000 · 12–20 months
Workspaces
Occasionally, and only when the brief is about how people work rather than how many desks fit. Usually a floor, not a building.
From €24,000 · 6–10 months

What a project
costs, roughly
Our fee is a share of the build budget, and the share falls as the project grows. Move the numbers and you will see the range we would quote before we have seen the drawings.

Selected work
2023 — 2025
Three of the last nine. The others are private and shown only in a meeting.
Villa Sund
- Year
- 2025
- Location
- Skagen, DK
- Type
- Residence, 240 m²
A summer house on the north coast, replanned around one east–west corridor so morning light reaches the kitchen and evening light reaches the bath. Oiled oak, recessed handles, sandblasted limestone at the thresholds. The 1961 roof structure was kept and left open.
Hotel Vinter
- Year
- 2024
- Location
- Åre, SE
- Type
- Hotel, 14 rooms
Fourteen rooms in a former mountain station. Each room keeps its own window proportion, so no two plans repeat — the material palette holds them together instead. Wool, waxed pine, blackened steel. Light is set at seated height, never overhead.
Kalk Apartment
- Year
- 2023
- Location
- Copenhagen, DK
- Type
- Renovation, 118 m²
A nineteenth-century flat taken back to lime plaster and replanned as four connected rooms with no corridor. Doors sit in line, so the full depth of the apartment reads from the entrance. Pale walls, dark timber floor, one long steel bench that serves as kitchen and table.

ProcessFive stages,
Five stages,
and where you decide
01
Visit
Two hours in the space with a tape measure and no laptop. Free, and about a third of these do not turn into a project — that is fine.
You decide: whether to go on02
Plans
Two or three ways of arranging the same rooms, drawn properly. This is where most of the argument happens, and it should.
You decide: which plan03
Material
Physical samples on your table, not a mood board. Timber, stone, plaster and metal in the thickness they will actually be.
You decide: the palette04
Drawings
Full set for the builder: joinery, electrical, thresholds, every handle located. What is not drawn gets improvised, so we draw it.
We decide: the details05
Site
Weekly on site until the last handle. We answer the builder’s questions so you do not have to.
Nobody decides: it just gets builtMaterialWhat we specify,
What we specify,
and why
Surfaces that age are chosen over surfaces that stay new. Everything below gets better looking after five years, not worse.
Oiled oak
Re-oiled once a year by you, in an afternoon. Scratches disappear into it instead of sitting on top.
Lime plaster
Breathes, so old walls stay dry. Repairs blend in rather than showing as patches.
Sandblasted limestone
At thresholds and in wet rooms. Grip when wet, and it takes a chip without looking damaged.
Blackened steel
Handles, shelf brackets, one long bench. Patinates by hand contact — it records where people touch.
Waxed pine
Cheap, soft, honest. Dents. We use it where dents are part of the point.
Undyed wool
Curtains and upholstery. Holds sound, and the colour shifts slightly with the light instead of staying flat.
StudioRefshalevej 213,
Refshalevej 213,
Copenhagen
Marenne was founded in 2016 by Ida Sund and Peter Roe. We take four commissions a year and stay on site until the last handle is fitted.
Material is specified in full thickness — timber, stone, plaster, metal. Surfaces that age are chosen over surfaces that stay new.
We are two architects and one project assistant. There is no third partner and no junior team drawing your flat — if you meet Ida at the first visit, Ida draws it.

Clients and pressWhat gets said
What gets said
afterwards
“They talked us out of the extension we came in asking for. The flat is the same size and it works twice as well — and it cost a third of what we had budgeted.”
“Fourteen rooms and not one of them feels like a hotel corridor. The restraint is the point.”
“What I did not expect was that they were still on site in month eleven, arguing with the joiner about a two-millimetre reveal. That is where the money went, and it shows.”
Questions
Asked at
Asked at
the first visit
If yours is not here, ask it in the form below and we will answer without a meeting.
Ask a questionWhy only four projects a year?
Because being on site weekly for a year is the part that makes the difference, and there are only so many weeks. A studio taking twenty projects sends a junior instead. That is a legitimate business; it is not ours.
How is the fee structured?
A percentage of the build budget, falling as the budget grows — roughly 16% on a small flat, 9% on a large house. Paid in five stages, tied to the five stages of work.
Do you work with our builder?
Gladly, if they will take drawings seriously. If we have never worked with them we will meet them before you sign anything.
Can you do only the drawings?
Yes, and about a fifth of our work is exactly that. It is cheaper, and the risk moves to you: what is not supervised gets improvised.
How long does it take?
Design is four to eight months. Build depends on the builder and the permits, and anyone who promises you a date before the survey is guessing.
Do you buy the furniture?
If you want us to. We buy at trade price and pass it through without a markup — our fee is our fee.
What if we disagree with the plan?
Then we draw another one. Stage two exists precisely so the argument happens on paper and not on site.
