In Situ Forma outdoor kitchen at golden hour in a Belgian landscape

BESPOKE OUTDOOR KITCHENS, CAST IN PLACE

Scroll
In Situ Forma — Belgium

Some outdoor kitchens are installed. Ours is cast — on site, in concrete finished with natural stone and noble wood, prepared by hand in our atelier in Belgium. Made to gather around, and to weather the years.

01 — Concept

Cast, not
delivered.

Most outdoor kitchens arrive in modules. Ours arrives as a mould. We build the formwork in the atelier, assemble it where the kitchen will stand, and pour the concrete on site. The final result is a unique architectural centrepiece, specifically designed for its location.

The method

The hand-chipped edge — evolved from an experimental concept to our signature look.

I

Survey

We read the site before we draw: orientation, prevailing wind, sightlines from the house, the level of the terrace. The kitchen is dimensioned for that place only.

II

Drawing

Plans and sections are drawn at the atelier table and reviewed with the architect, if requested. Nothing is standardised — module widths, counter heights and appliance positions follow the drawing.

III

Formwork

The mould is built by hand in Tielt. Every visible face of the finished concrete exists first as a negative in the atelier.

IV

Pour

The formwork travels to the site, is assembled where the kitchen will stand, and the concrete is poured. It cures in place. After stripping, the surfaces are ground and sealed by hand.

02 — Materials & Equipment

Chosen for
decades.

Authenticity is reflected not only in our creation process, but also in the materials we select. Every surface is chosen for how it ages.

The body

Concrete
Architectural concrete, poured on site and hand polished after stripping. Pigment is mixed to a sample approved before the pour; terrazzo aggregates are optional and specified per project.
Stone & marble
Marble from the quarries at Macael, in Andalusia, chosen slab by slab rather than by catalogue reference. The veining decides as much as the stone does: which way the lines run, and how they meet the concrete, is settled before anything is cut.
Noble woods
Solid European walnut and oak, oiled by hand. Against the cool grey of the terrazzo, the grain reads warm.

Built in

PITT Cooking
Individual gas burners set directly into the stone. No hob frame, no visible housing — flame and surface, nothing between them.
Fhiaba
Timeless design combined with outstanding technical capability. The right cooling and wine storage options for your project.
MGS
Solid stainless taps, chosen to hold their finish in salt air. Their range is broad enough that the tap can follow the drawing instead of limiting it.
BBQ
A custom-made plancha drawn for each kitchen and built to its dimensions.

Every project begins on a blank page. What is named here is what earlier drawings asked for, not a range to choose from. When a design calls for another stone, another wood or a maker we have not worked with yet, we go and find them.

03 — Craft

Crafted in
Belgium.

Every kitchen begins at the drawing table in our Belgian atelier, where the design takes shape and the formwork is built by hand. Every mix is cast as a sample before it is cast as a kitchen. Our standards set our capacity: we take on only a limited number of projects each year, so each receives our full attention from the first sketch to completion.

04 — Projects

ISF 001
Pittem, BE

The first kitchen cast under the In Situ Forma name. Poured in an open field, in the summer of 2025, and left to weather there.

Location
Open field beside the client’s house, Pittem, West Flanders.
Year
Drawn spring 2025, poured July 2025.
Body
Single volume in architectural concrete, cast on site in one pour, ground and sealed by hand. Hand-chipped sides mark the signature style of this design.
Surfaces
Terrazzo counter with locally sourced aggregate; oiled solid walnut to the serving side.
Equipment
A custom-made plancha with the steel plate set flush with the concrete, so the cooking surface and the counter read as one. A bottle cooler cast into the top, finished with a walnut base.

ISF 002
Tielt, BE

Our second project has just been completed in the summer of 2026. Cast in place within an enclosed garden, where every millimetre was set against existing walls and planting. The creation will be featured here soon — photographs are coming in September 2026.
