Under-stairs / sloped-ceiling unit
Turn your loft into clever storage
Under the eaves, every centimetre counts. We build wardrobes, shelving and cupboards that follow the exact angle of your slope — right where standard furniture leaves space wasted.

Why custom
The only way to use a sloped ceiling
Follows the roof angle
The unit hugs the slope to the degree, from floor to low point.
Hanging space, drawers, doors
A layout matched to the height available at each point.
Zero wasted space
We reclaim the space standard furniture throws away.

Designed for your slope
Measurements, plan, build
A sloped-ceiling unit calls for precise design. Two options:
- ✓You're in Auvergne-Rhône-Alpes — we come to measure and install
- ✓Elsewhere in France — we guide you through taking the measurements, then build and deliver
- ✓Decor, finish, layout — your choice, all visible in the 3D configurator
How it works

Made in Isère

Fitted at your home
An under-slope unit is fitted on site: our own team brings it and installs it, within Auvergne-Rhône-Alpes. Elsewhere in France, write to us before you commit.
Your questions
Lead times, warranty, returns
What is the lead time for a custom sloped-ceiling unit from Casavoilà?+
Allow two weeks at most between the workshop confirming your layout and the fitting: building it takes 4 working days, the rest is agreeing a date with you. Each piece is cut and assembled to order in our workshop in Saint-Savin (Isère), then brought and fitted by our own team, within Auvergne-Rhône-Alpes: a unit cut to the angle of your roofline is not shipped flat-packed. Elsewhere in France, write to us: we look at transport and fitting before anything is built.
What warranty comes with this sloped-ceiling unit?+
Every sloped-ceiling unit is checked at the workshop before shipping, then guaranteed for 10 years on its structure and 5 years on its moving hardware against any manufacturing defect, on top of the statutory warranties of conformity and hidden defects. A defect must be reported within two months of its discovery, with your order number and photos: if it is covered, we remake the part. Terms and exclusions: article 7 bis of our terms of sale.
Can this sloped-ceiling unit be returned?+
An under-slope unit is built to your exact measurements, to the angle of your own roofline: it counts as goods made to the consumer's specifications, which the law excludes from the 14-day right of withdrawal (article L221-28 3° of the French Consumer Code), as it does any goods made to the consumer's specifications. That is exactly why the workshop checks your two measurements and approves the 3D layout before a single cut is made — and why this piece is not bought in one click. Your statutory warranties of conformity and against hidden defects remain untouched.
