What should the room become?
A fit out does not start with a list of trades, it starts with a question. Only once you know what the room has to do does it become clear which layers it needs. A room for working makes different demands on acoustics and light than a bedroom, and that decides the wall, the ceiling and the floor.
Living
A room people stay in. Warm surfaces, quiet transitions and a floor that belongs with the rest of the home.
Working
Concentration depends on acoustics. Suspended ceilings and insulated wall linings take the reverberation and the noise from the next room out of the space.
Rest
Sleeping and retreat need sound insulation inwards. How the wall and ceiling are built up decides what actually reaches the room.
Dividing
One large room becomes two usable ones. Drywall partitions change the layout without touching the structure of the building.
Utility
Utility room, storage, workshop. Hard wearing surfaces and an easy floor matter more here than any styling.
What is possible in a particular room depends on what is already there: the ceiling height, the existing substrate and the building services. That is settled on site, not in advance over the phone.
A room is built in layers.
Interior fit out is not one job, it is a sequence. Each layer sits on the one before it, and every late correction costs more than an early decision. The drawing shows the same room in seven states.
Select a layer to highlight it in the drawing.
It begins with the room as it stands: bare ceiling, bare walls, bare floor. Height, layout, window positions and the existing services set what is sensible.
Drywall partitions divide the room up again. A lining stands in front of an existing wall and creates the cavity that insulation and services fit into.
A suspended ceiling calms the room and takes up services. The shadow gap at the edge separates it cleanly from the wall instead of butting it up against it.
Insulation goes into the cavity between the studs. It works against heat loss and against sound at the same time, and it cannot be reached again afterwards.
The covering is only the last layer. What decides the result is the substrate underneath: level, sound and dry. Laminate, parquet, vinyl, tiles or carpet come after that.
An internal door sits on the seam between two rooms. The frame, the gap and the junction with the floor decide whether the transition reads as calm or as an afterthought.
Filling, wallpapering, painting or coating. The surface is what remains, and it shows every inaccuracy in the layers below it.
The drawing is schematic and shows a typical build up, not a particular job. Which layers make sense in your room comes out of the site visit.
Six trades that interlock.
The services MK-AUSBAU offers are not six separate products, they are six layers of the same room. They are planned in the order in which they are built.
-
01 / 06
Drywall and acoustics
The structure of the room. Partitions change the layout, linings create cavity, suspended ceilings take up services and calm the acoustics.
- Partitions and wall linings
- Suspended ceilings
- Sound insulation and acoustic treatment
- Fire rated walls
- Design elements in plasterboard
-
02 / 06
Insulation
The comfort of the room. Insulation works against heat loss and against sound, and it belongs in the same operation as the framing that precedes it.
- Internal thermal insulation
- Acoustic insulation
- Vapour control layers and vapour barriers
- Insulation in a range of materials
- Advice on insulation
-
03 / 06
Internal door fitting
The transitions of the room. Doors sit where two rooms meet, and an accurate fit decides both how they work and how they look.
- Room doors in a range of materials
- Sliding and folding doors
- Glass and designer doors
- Frames and ironmongery
- Made to measure work
-
04 / 06
Floor coverings
The surface everything stands on. Before the covering comes the preparation of the substrate, because no covering rescues an uneven screed.
- Laminate and parquet
- Vinyl and PVC floors
- Tiles and natural stone
- Carpet
- Substrate preparation and screed work
-
05 / 06
Painting and coating
The finish. Filling, wallpapering and painting close the room off and make visible how cleanly the layers underneath were worked.
- Interior painting of every kind
- Wallpapering
- Filling and skim techniques
- Wood protection and glazes
- Decorative coatings
-
06 / 06
PU design floors
A seamless floor with a three dimensional appearance, for rooms where the floor is meant to be the element that shapes the space.
- Epoxy based design floors
- Individual motif design
- High gloss sealing
- Slip resistant surfaces
- Seamless installation
Not included: electrical, plumbing and heating, structural engineering, windows and external elements, and architecture or planning applications. Where such work belongs to a project, that is discussed before anything is commissioned.
From bare room to finished interior.
The same room, seven states. Drag the slider to build the fit out up layer by layer. The drawing shows what is added where, and what can no longer be reached afterwards.
Use the arrow keys or drag to build the room up layer by layer.

This sequence is the usual route through an interior fit out. It is not a fixed schedule and not a description of a particular job.
The trades and materials in pictures.

These pictures come from MK-AUSBAU and illustrate the trades and materials of an interior fit out. They do not document a particular building project and are not a promise of a particular result.
One point of contact for the whole fit out.
MK-AUSBAU coordinates the trades of an interior fit out as principal contractor: drywall, flooring, painting and fitting all run through one place. For you that means less to coordinate, a sequence that works, and one person to ask when something comes up.

A fit out is only finished when the transitions are right.
Qualität und Präzision seit 2016
-
One place for everything
You discuss the project once. Splitting it across the trades happens inside the company afterwards, not on your desk.
-
Sequence instead of rework
Insulation before boarding, substrate before covering, surface last. Keep the order and there is less to open up later.
-
One result, not six invoices
The room is treated and handed over as a whole, not as the sum of separately commissioned jobs.
What is not included
Electrical, plumbing and heating, structural engineering, windows and external elements, and architecture or planning applications are not services of MK-AUSBAU. If a project touches on them, that is said openly before anything is commissioned.
How a project runs.
Six steps from the first call to handover. Nothing to pay and nothing to commit to before the quotation is with you.
-
01
Enquiry
You describe the project briefly: where it is, what kind of building, and the work you have in mind. A few sentences are enough to start.
-
02
Site visit
The room is looked at in person. Height, substrate, connections and condition cannot be judged from a distance.
-
03
Quotation
After the visit you usually receive a quotation within 3 to 5 working days, listing the items that genuinely apply.
-
04
Planning
Materials are settled and the trades are put into an order, so that no layer is built onto an unfinished one.
-
05
Carrying out the work
The work runs in the planned sequence. Changes are discussed before they are made.
-
06
Handover
The finished room is walked through together. Anything noticed is recorded and put right.
Heinsberg and the district.
The company is based in Heinsberg. Most work is in Kreis Heinsberg and the surrounding area, and for larger projects further afield in North Rhine-Westphalia.
In Kreis Heinsberg
- Heinsberg
- Hückelhoven
- Erkelenz
- Geilenkirchen
- Wassenberg
- Wegberg
- Übach-Palenberg
- Gangelt
- Selfkant
- Waldfeucht
And beyond
- Mönchengladbach
- Aachen
- Nordrhein-Westfalen
The towns of the district are listed here as a geographic statement. Whether a particular project can be taken on depends on its scope and timing and is settled when you enquire.
Common questions.
What people most often want to know before enquiring.
Mainly Kreis Heinsberg together with Geilenkirchen, Erkelenz and Mönchengladbach. Larger projects are also taken on elsewhere in North Rhine-Westphalia.
Yes. MK-AUSBAU coordinates drywall, flooring, painting and fitting as principal contractor for interior work. You deal with one contact instead of several firms that have to coordinate among themselves.
Usually within 3 to 5 working days of the site visit. Interior work cannot be estimated honestly without seeing it, which is why the visit comes first.
Not necessarily, though it helps. What has to be cleared and what can stay is discussed at the site visit, because it depends on the extent of the work.
No. Those trades are not part of the service. If a project touches on them, it is raised before anything is commissioned so that the sequence still works out.
Yes. A complete fit out is possible, but so is a single partition, one floor covering or a door installation. What makes sense depends on the condition of the room.
