FAQ

Our office containers and knock-down units come in four main models: KO, PH, WL and WH.

Sizes start at 2.00 x 3.00 m. For larger spaces we join two or more units together and build to the customer's design.

The KO model is our most affordable option for tight budgets, starting at 2×3 m and 49,900 baht per unit.

Next, the economy-structure PH model, 3×6 m, from 119,000 baht per unit.

The WL model has a heavy structure that can be stacked two storeys high, 3×6 m, from 129,000 baht per unit.

And finally the premium WH model, 3×6 m, from 149,000 baht.

The walls aresandwich panels — colour-coated steel sheets on both faces with heat insulation in the middle.

Outside temperature is the main factor, but the PU foam insulation keeps the interior temperature stable, retaining cool air and blocking heat from outside.

Our office containers are already designed for outdoor use.
If you add a roof, it will extend the unit's service life even further.

For a single-storey unit, simply compact the soil or pour a concrete slab over the required area.
For two-storey stacking, additional piling may be needed to prevent settlement.

Yes, they can be added. Please ask our sales team for pricing.

Leaks can have several causes, such as ground settlement or improper lifting and relocation. Newly manufactured units come with a 1-year leak warranty (ask our sales team for details).

Yes, but the warranty will be void.
Tip: each wall panel can hold roughly 30 kg.

The floor supports 100–150 kg (depending on the model), with the weight spread evenly.

We use LED bulbs, which are available at any hardware store.

The right BTU depends mainly on room size (width x length) and factors such as sun exposure, ceiling height, number of occupants and electrical appliances. Our standard is 18,000 BTU.

Any number of units can be joined, but the ground must be firm and settlement-free, because the site is the key factor when joining units.
If the ground is not firm, the units will settle, leaks will occur, and doors and windows will stick and become hard to open.

It depends on what you compare it with.
On leased land, a container unit beats conventional construction 100%: when the lease ends you simply move it, paying only for transport instead of building again.

It depends on the intended use and your budget.
For an office thatdoes notreceive customers: a standard unit with one door and one window is enough.
For an office that receives customers: add some glass at the front so customers can see in (how much glass depends on your budget).
For a country retreat: we recommend a built-in bathroom and not too much glass (it may be less secure when the house is often unoccupied).
For a permanent home: whatever suits your budget and taste.

10 years or more, with regular care and maintenance.

Office containers weigh from 800 kg.

Yes — either partitioned inside the unit or as a separate unit.

Yes. We recommend a Western-style kitchen; a Thai-style (heavy wok cooking) kitchen is not recommended.

Yes, we can build them to your requirements.

Pre-zinc box steel 2–2.3 mm thick, sprayed with epoxy anti-rust primer and finished with a top coat.
Polyurethane

Level and compact the soil first. We include support blocks free with every unit (they help extend the unit's service life).

By 6-wheel crane truck.

The insulation can ignite but does not spread flame — it self-extinguishes. Other materials are flammable.

Connect external power via the (male) power plug using VCT cable size 2.5, 4 or 6 (minimum 2.5, single-phase). For units with air conditioning use VCT size 6 or larger, 220 V, and remember to install a ground wire.

No problem — our Connex House units can be assembled on site, however small or narrow the space.

Just tell us what you need — our sales team helps with design at no charge.
