Use scenarios
From a family garden to a public botanical garden.
The use scenario comes first. Only then do we match size, structure, transparent envelope and microclimate level.
Seedlings, seasonal vegetables, herbs, collections.
A garden room, citrus, exotic plants, a place to sit.
A BIO classroom, a school laboratory, a community demonstration garden.
A restaurant herb garden, a hotel orangery, a spa and wellness space.
A nursery, a specialist crop, hydroponics, controlled production.
A botanical garden, a tropical hall, science, education and tourism.
Envelope technologies
A transparent dome works only when every layer is coordinated.
The envelope is chosen for the project: light need, condensation, wind and snow, service life, replaceability, fire class, cleaning and budget.
GEODOMAS · envelope concept
One geometry is not enough.
Structure, skin, air gap, ventilation, condensate collection, doors and service access have to work together.
AI visualisation · not a technical detail. Materials and joints are chosen for the specific project.
ECO
Double transparent PVC
An economical modular direction: transparent outer PVC, a controlled air cavity and an inner tensioned membrane.
HEAVY
Reinforced double PVC
A thicker transparent outer skin and a stronger fixing logic. Chosen only after a site load analysis.
PC
Polycarbonate system
A stiffer modular envelope with joint profiles, seals and designed opening elements.
ETFE
ETFE direction
A light envelope for long spans. Cushions, pressure, foil layers and controls are designed individually.
GLASS
Glass and a hybrid facade
Steel or aluminium, safety glass / insulated glass units and, where it makes sense, ETFE in the higher zones.
Outer transparent PVChistorical ECO precedent 625 g/m² · 0.55 mm; reinforced class about 0.8 mm
150–200 mm air cavity under studycondensation, ventilation, pressure and maintenance are designed
Inner transparent tensioned membraneit closes the air buffer, but is not by itself a certified thermal insulation
Reality check: a double transparent layer is a buffer envelope. Its thermal behaviour, condensation regime and fitness for a given climate are set by the real detail, the materials and the project.
Primary load-bearing structure
For a humid greenhouse environment — not a timber frame by default.
A greenhouse lives with high humidity, condensation, irrigation and temperature cycles. The standard GEODOMAS BIO structure is therefore built from longer-lived systems.
A frame ready for fabrication
Geometry and fabrication have to match.
A geodesic frame is not just a pile of raw tube. It needs exact lengths, cutting, pressing or forming, drilling, matched nodes, marking, corrosion protection and production control.
AI concept visualisation · not a technical drawing. Frame geometry and nodes are designed individually.
C0–C4 microclimate packages
From natural air movement to a full CEA system.
Historical GEODOMAS projects already joined a weather station, indoor sensors, vents, heating, shading, mist, irrigation, software and a control network. A current project takes only the level it actually needs.
NATURAL
Doors, low-level air inlet, a high vent, manual control.
PASSIVE
Thermo-automatic vents, a shade screen, passive airflow.
ACTIVE
Fans, heating, irrigation, mist or another active cooling path.
SMART
Sensors, a weather station, actuators, remote control, alerts and history.

An indicative model family
Size helps to route the enquiry, but it does not replace the project.
Below is the current state of the knowledge base. “Historical precedent” means GEODOMAS has an earlier source, but a new offer still checks live drawings, the BOM, materials and site loads.
| Technical key | Nominal size | Possible use | Knowledge status |
|---|---|---|---|
| BIO28 · Ø6 F3 | 28 m² · H3,6 m | Nursery, household, BIO classroom, mini orangery | historical precedent |
| BIO50 · Ø8 F4 | about 50 m² · H4 m geometry family | Orangery, education, a small AGRI building | geometry / BOM under check |
| BIO78 · Ø10 F4 | 78 m² · H5 / H5.5 — being confirmed | Orangery, public garden, AGRI | height version to be chosen |
| BIO95 · Ø11 F4 | 95 m² · height under check | A professional orangery, AGRI, a display | archive figures do not match |

| BOTANICAL BIOME | Ø20–40 m+ | Public botanical garden, tropical biome, science, tourism | individual project |
Pricing rule: the final price is not calculated from diameter or floor area alone. It needs an exact geometry revision, envelope quantity, structural direction, openings, microclimate, site and the scope of responsibilities.
BOTANICAL BIOME
A botanical garden as architecture, a climate system and a visitor journey.
A large biome is not “a very large greenhouse”. It is structure, facade, heating, cooling, humidity, smoke control, access, evacuation, root zones, water treatment, lighting and maintenance logistics.
Historical GEODOMAS concept

A central node, three Ø34 m halls of different heights, six smaller modules and nine link tunnels.

Circular farm integrations
A dome can become part of a closed farm ecosystem.
These modules are not included in every BIODOME by default. They are connected only when the project has a real technical and economic reason, and named specialists are appointed.
Rain collection, tanks, filtration, irrigation, condensate and drainage control.
Nutrient mixing, pumps, dosing, sanitation, return flow and an emergency mode.
A closed fish-and-plant water system is possible only with aquaculture and water-technology partners.
Sun, wind, storage, the heat source and the building's actual energy balance.
Compost or biogas is assessed as a separate farm technology, not as a property of the dome structure.
Growing technologies
Hydroponics, aeroponics and automated control.
Inside the dome the growing system is matched to the chosen plants, water quality, lighting and the maintenance that is actually available. It is extra project equipment, not the standard kit of every BIODOME.
Hydroponics
Nutrient solution for the roots
Plants grow without soil and take nutrients with the water. Channels, tanks or substrate modules are chosen for the crop and the root zone.
The project provides a solution tank, circulation, filtration and return. pH, electrical conductivity (EC), solution temperature and level are checked.
Aeroponics and vertical modules
More growing levels
In aeroponics the roots are held in air inside a closed chamber and wetted by a sprayed nutrient solution. The shape of a vertical tower does not by itself define the technology: that depends on the irrigation system inside.
When the equipment is chosen, nozzles, wetting cycles, filters and cleaning access are checked. Pump-fault indication and an emergency supply are provided for.
Images from the GEODOMAS Ø6 m BIO presentation, slides 26 and 29. They are examples of technologies, not proof that the equipment shown is installed in a specific GEODOMAS building. Hydroponic and aeroponic principles: Oklahoma State University. The kit and the control limits are agreed during design.

Common questions
What is worth knowing before you choose a BIODOME?
A transparent shape looks simple, but in use the decisive things are humidity, condensation, wind, ventilation, maintenance and the real plant regime.
Can a BIODOME run all year?
It can be designed for a season, an extended season or 12 months of use. The result depends on the local climate, the envelope, heating, ventilation, humidity, light and the indoor temperature you want.
Is the cheapest double PVC thermal insulation?
Not automatically. An air cavity can reduce the direct effect of heat and condensation, but the real U-value and the dew-point regime must be calculated or tested for that specific assembly.
Why do you not recommend timber for the primary frame?
Continuous humidity, condensation, irrigation and temperature cycles raise the risk of biological damage and of nodes losing stability. The standard BIO direction is developed in galvanized steel, aluminium or a verified FRP system.
Can we start with one small dome?
Yes. A sound path is a pilot Ø6 m nursery or orangery, but the places for doors, tunnels and service entries should be agreed in advance with the future expansion.
Who is responsible for the hydroponic yield?
GEODOMAS can integrate the building, the climate, the technical rooms and the control interfaces. Crop recipes, nutrient chemistry and biological guarantees must be confirmed by a named agronomy or CEA partner.
Can a price be given from the diameter alone?
Only a very preliminary direction. The final price needs exact geometry, structure, envelope area and material, openings, microclimate, foundations, logistics and the scope of installation.
How does an orangery differ from a commercial greenhouse?
In an orangery, architecture, the visitor experience and the display come first. In a commercial greenhouse the first measures are production flow, area per unit, microclimate stability, servicing and OPEX.
Are the figures in historical GEODOMAS presentations guarantees?
No. Older statements about temperature, wind, snow, water saving, yield or service life are treated as an R&D precedent until they are checked with current materials and the calculations of the specific project.
Do you have a plot, a garden or a farm idea?
