Floating desk.

A place to work.
Designed to leave space.

01 / Starting with a feeling

Less in the way.
More room to think.

I wanted a clear glass surface, a clean computer setup, and room to move underneath without bumping into bulky desk legs.

The first sketch borrowed a thought from architecture: flying buttresses. A support could curve towards the surface, carrying its weight while leaving the space around it open.

That became a pair of cantilevers, one on either side. The challenge is making something that looks light feel steady in everyday use.

02 / Designing around a day

A desk is also
a place to do things.

The objects make the idea concrete. Where do I write? How do the two screens line up? Is there room to play a few notes without rearranging everything?

03 / Top downA place for work, writing, and a little music.
A

Work, in the centre.

A 16-inch MacBook is the typing surface, with a Studio Display above it. Screen alignment and the adjustable stand are part of the layout study.

B

Writing, to the left.

An angled A5 notebook and a pen sit on my writing side. I’m left-handed, so this space deserves as much attention as the screens.

C

A little music, to the right.

An Akai MPK Mini and AirPods Max have their own place. A curved metal headphone holder continues the language of the desk supports.

A second direction / Sit to stand

The same idea.
A different height.

A standing version explores how the glass surface and curved supports could move together on telescopic columns, rising from 740 to 1,160 mm.

The aim is to change posture without rearranging the workspace. The animation shows the movement concept; the lifting mechanism and its stability still need development.

03 / From an image to an object

Looking light.
Holding up.

A convincing render is only the beginning. The next questions are about bending, balance, connections, and how someone would actually make it.

FreeCAD / CalculiX · original round-tube frame

What a lean on the front edge reveals.

An additional 40 kgf (392 N) acts over a small patch at the front centre, on top of self-weight and the earlier equipment loads. These are saved FEM results, not physical measurements.

Steel frame

von Mises stress

Saved FEM nodal stress field for the steel frame under 40 kgf additional front-centre load. The peak is 229 MPa; hotter colours appear around the curved supports and roots.
Actual deformation scale ×1. Grey shows the undeformed geometry.

Glass top

Maximum principal tensile stress

Saved FEM tensile stress field for the glass top under the same 40 kgf load, with a peak of 16.7 MPa. This model assigns no glass fracture limit.
Peak: 16.7 MPa. No glass fracture limit is assigned.

Ideal retained pads and fixed frame roots. Earlier equipment layout; the MPK Mini and revised fittings are not included. This is a preliminary linear-elastic study, with large-deflection limitations at this load.

The load sweep

Flexibility becomes a problem before a load rating.

Load sweep from 0 to 75 kgf additional front-centre force. Predicted sag rises from 11.8 to 61.5 mm; peak steel stress rises from 72 to 367 MPa. The curves become dashed beyond the assumed S235 first-yield threshold of about 42 kgf.
Self-weight and equipment already produce 11.8 mm of predicted sag. Dashed curves in the shaded region are linear extrapolations beyond assumed first yield, not predictions of collapse.
What the model assumes

Round steel tubes: 28 mm outer diameter, 2 mm wall. Hypothetical S235 steel, with a 235 MPa yield threshold. The glass is modelled elastically without a fracture criterion. The front load acts over a 150 × 60 mm patch rather than a single point.

The sweep uses linear superposition of saved solver cases. It assumes that the glass is positively retained: loose pads cannot hold the current top in static balance. Real adhesive bonds, welds, floor contact, tipping, tube buckling, impact and fatigue are not validated.

The fine mesh contains 90,498 nodes and 15,972 elements. A two-mesh comparison changed front-centre movement by up to 2.8% and peak steel stress by up to 6.4%. Neither these results nor the estimated first-yield threshold establish a safe working load or a service life.

05 / Reading the structure from the side
The section

Round or oval?

The rendered frame uses round tubes. I’m also studying a 28 × 40 mm oval section: deeper in the direction of bending, while keeping a narrow profile from the front.

The load

More than the things on top.

The glass and equipment are only part of the load. Leaning on the front edge creates a different, more demanding case. Preliminary simulations exposed too much flexibility in the original thin frame.

The connections

The small details carry weight.

Retaining the glass, preventing sliding, and attaching the headphone holder need their own checks. Adhesive pads and the flush fitting are concepts, not validated connections.

04 / Still on the drawing board

The next step
is something real.

Compare tube sections. Resolve the glass supports and fittings. Get feedback from tube-bending workshops around Paris, then revise the design around what can be made and tested.

I’m interested in that whole path: sketching something I’d love to use, understanding its limits, and turning it into a physical object.
