Artisan stove builder · thermal engineering · Burgundy
A masonry heater calculated for your house,
built by hand.
Each heater is sized for a specific volume, lifestyle and house — then built in masonry with materials that last for decades.

Before anything else
A masonry heater is not a wood stove.
The difference comes down to one idea: mass.
| Criterion | Conventional wood stove | Masonry heater |
|---|---|---|
| What heats up | the air, as long as the fire burns | the material, which then releases heat for hours |
| Firing rhythm | reloading every hour or two | one or two burns a day |
| Heat as you feel it | hot, dry, stratified air | radiant heat, like the sun on your skin |
| What you buy | a mass-produced appliance | a masonry structure, sized for one house |
This table does not say a masonry heater is better: it says it meets a different need. The flip side of thermal inertia is slowness — it will not warm a room in ten minutes, and it weighs enough that the floor has to be checked before it is built.
The mass, hour by hour
One burn, twenty-four hours.
11 h
The fire is out. The mass radiates, like sunshine on your skin.
Illustrative curve, not measured. The heat calculation for your project gives you your own.
The method
Made-to-measure is not a style.
It is a sequence of calculations.
01
Study & design calculation
Plans, volumes, consumption figures: the heater is sized for your house, not picked from a catalogue.
02
3D design
The 3D drawing settles the technical and aesthetic choices before the first brick: you see your heater before it exists.
03
Workshop preparation
Cutting and dry-assembly of the heater core in our workshop: the time spent on site in your home is shortened accordingly.
04
Construction & installation
Masonry, connection to the flue, commissioning: a single point of contact, qualified in both flue work and masonry.
05
Handover & documents
User manual, heater data sheet, instructions, handover report: your heater is delivered with its paperwork.
The proof is in the projects
