3D-printed houses in Batumi: what is realistic on a plot in Georgia

We are asked about 3D-printed houses in Batumi and elsewhere in Georgia more and more often, yet the local market has almost no answers. We have not built a printed house ourselves. But in a seismic zone such a house is structurally closest to cast-in-place concrete and reinforced masonry, which we build all the time, so we can assess a printing project in practical terms. Below is what is known about the technology worldwide, what Georgian conditions change about it, and what we can offer if you like the idea itself.

How a house is printed

A construction printer looks like a giant piping bag mounted on a gantry or a robotic arm. Layer by layer, it extrudes a special cement mix along the outline of the walls, and a wall rises to full storey height in a few shifts. Usually two thin skins are printed with a cavity between them, and the cavity is later filled with insulation or with reinforced concrete.

Only the walls are printed. The foundations, floor slabs, roof, windows, services and finishes are done just as in an ordinary house, and they account for most of the estimate. Printing's strength is shape: the printer makes smooth curves and round walls without formwork, while on an ordinary build a wall like that is expensive.

3D-printed houses in Georgia: what we know as of 2026

Printed houses have been built in Europe, the US, China and the Middle East since the mid-2010s, mostly single-storey and two-storey ones. Almost every such project went through its own approval: the mix and the wall were tested in a laboratory, and the calculations were done for that particular house. In some places dedicated test methods for printed walls have already appeared, but there is no common standard recognised by every country.

We have found no information on completed printed homes in Georgia with publicly available documentation. Nor have we come across specific rules for such walls in the Georgian codes, so the wall would have to be justified by calculations and testing, like any non-standard structure. As for any house, the permit procedure depends on the class of the structure; there is more about the classes in our section on construction. But a project like this will face more questions.

Earthquakes and reinforcement

The main constraint in Batumi comes from earthquakes. A printed wall is made of layers, and the joint between them is weaker than the concrete itself. In a tremor the wall is pulled and sheared, and unreinforced concrete performs poorly in tension and shear. So in a seismic zone vertical reinforcement is placed in the cavities and encased in concrete, horizontal bars or mesh are laid between the layers during printing, and a reinforced concrete ring beam is cast along the top of the walls under the slab.

At that point the printed wall essentially becomes permanent formwork for reinforced cores. It works well, but some of the advantage is lost: the reinforcement is tied by hand, the concrete is poured as a separate stage, and every joint needs a calculation. The closest familiar equivalent to such a wall is permanent formwork: its blocks are assembled by hand on the plot and filled with reinforced concrete in the same way. How we build seismic resistance into a structure in general is described on the page about earthquake-resistant houses.

Rain, heat and salt during printing

The printer works in the open air, and fresh layers must not get wet or dry out too much. In Batumi a downpour can come in any month, so the site needs a tent over it for the whole time printing is under way. In summer heat the mix sets faster, and printing has to be done early in the morning or in the evening, otherwise the next layer bonds poorly to the one below.

By the sea, an outer skin of cement mix needs protection like any concrete: salt and moisture get into its pores. On the outside the printed wall is covered with vapour-permeable render or a ventilated facade anyway, and the ribbed texture of the layers, which looks so good in photos, often ends up hidden under the finish.

Printer, mix and crew

The equipment and operators would have to be brought in from abroad, and the cost of delivering the gantry and assembling it on site falls entirely on the estimate for a single house. The printing mix has to hold its shape as soon as it leaves the nozzle and still bond with the layer below. Ordinary concrete from a local plant doesn't behave like that, so the mix is ordered from the printer manufacturer or developed from local materials, with testing. Either route adds months before construction can start.

The economics of printing are better when a series of identical small houses is printed on one site: the printer is assembled once, and the crew gets into its stride. For a single private house this advantage almost disappears.

What we offer instead of printing

Interest in 3D printing usually comes from one of three wishes: an unusual shape, a warm wall without thermal bridges, or a fast build. Each of them can be achieved in Batumi with familiar methods:

• smooth and round walls are made in cast-in-place concrete with curved formwork or in masonry laid to a template, and we work out the shape together with the facade design;
• a warm wall with a concrete core comes from permanent formwork, or from a cast-in-place concrete frame with block infill and continuous insulation on the outside;
• a fast build comes from a factory-made modular house, if a truck carrying a module can get to the plot.

If you still want a printed house and have found a company with a printer, start with a check. The structural engineer will review the test results for the mix and the wall and tell you whether such a structure passes the calculation under the Georgian code on your ground. If it does, we can discuss an arrangement in which the company with the printer prints the walls under its own contract and we carry out the rest of the work. We agree on this after the check, once the structure is clear and so is who is responsible for what.

How much a 3D-printed house costs in Georgia

There is no market price for a 3D-printed house in Georgia, so there is nothing to compare it with. Based on European projects and Georgian finishing prices, we estimate that such a house would cost from 2,880 ₾ per m² turnkey. That price covers printing the walls on the plot, the foundations, floor slab, roof, building services and mid-range finishing. The shell, meaning the walls, foundations, floor slab and roof, would cost from 1,470 ₾ per m² by the same estimate.

For comparison, our prices are: a cast-in-place concrete house shell from 1,110 ₾ per m², an aerated concrete one from 750 ₾, a mid-range turnkey house from 1,680 ₾, and a factory-built modular house, turnkey, from 1,830 ₾. The design is priced separately in any case, from 100 ₾ per m². Printing costs more because of the delivery of the printer, the reinforcement of the cavities for seismic loads, the tent for the duration of the work and the testing needed for the permit. The final cost is set on the basis of the design, after a visit to the plot and once the estimate is agreed, and for printing it may differ from our estimate in either direction.
