Complex furniture assembly –
when DIY stops making sense
Ceiling-height wardrobe walls, corner combinations, sliding doors, heavy wall mounting in century-old walls: some projects need two pairs of hands, specialist tools and experience. That is exactly what we do – with a fixed-price quote before the appointment.
What makes an assembly complex
Complex means: multiple frames that must be aligned to each other on sloping floors. Sliding doors calibrated to the millimetre. Corner units with hidden connectors. Filler panels and trims for a ceiling-height built-in look. We have completed over 500 such assemblies – the gallery shows real projects.
Altbau buildings are our specialty
Berlin Altbau means 3-metre-plus ceilings, plank floors that slope several centimetres and walls where ordinary anchors will not hold. We level bases to compensate the floor, match fixings to the wall type (hollow brick, clay plaster, drywall) and anchor heavy fronts safely.

Frequently asked questions
At the latest for sliding doors, corner combinations or wall mounting on old walls. Mistakes there cost more than the assembly: warped doors will not run, wrong anchors will not hold.
Yes. We know the connector systems of the major manufacturers and also assemble second-hand or modified combinations without the original manual.
For PAX, use the online calculator. For everything else, send photos and measurements via the custom quote form – you receive a binding fixed price before you book.
Depends on the project. Ceiling-height combinations and heavy fronts are assembled by a team of two – already included in the fixed price.
