Interactive buying guide
Know what you are buying, before the quote goes out
A modular building is easy to picture and hard to compare. This guide takes you from “which product?” to a written project brief — what the buildings are, what arrives on site, what is included in the price, and what still needs to be confirmed.
A decision tool, not a contract. Every final scope is confirmed in writing per order.
01
Find your starting point
Your use, destination, quantity and local installation resources decide which product line is worth comparing first. Take the four quick steps below; anything you skip stays “to confirm”, not guessed.
Your starting point
Answer the questions on the left and a short direction appears here — which product line to compare first, and why. Nothing is final: this is a way to focus your reading, not a specification.
02
Explore what makes up your building
Open the concept model to see the structure, enclosure and services. Discover what to check before you order.
Concept view — not an installation sequence or engineering drawing. No dimensions, materials or equipment models are implied.
What you stand on and its underside
The finished floor carries people, furniture and equipment. Its make-up affects stiffness, comfort and how the building sits on its base.
- Confirm before ordering
- The floor construction and loading for the intended use (a dormitory and a kitchen differ), and any underfloor insulation or protection for the climate.
- On site
- Following the delivery plan, confirm installation of the floor sections, joints and any final finish.
The lid that takes weather and sun
The roof sheds rain, carries wind load and — in hot climates — takes the most solar gain, so its build and the joint sealing matter.
- Confirm before ordering
- The roof construction, how it is joined and sealed, and any insulation or finish for your climate.
- On site
- Lifting and landing the roof section, then making and checking every joint and seal.
- Confirm before ordering
- Panel construction and insulation, and any fire-test reports that apply to the model.
- On site
- Lifting and fixing panels, then sealing every joint so the envelope stays weather-tight.
Where light, comfort and cost meet
Windows and doors are where comfort, security and cost meet. They are usually configurable, but very large or structural openings may need a factory review first.
- Confirm before ordering
- Glazing and door options, and any structural change a very large opening would require.
- On site
- Fixing and sealing glazing and doors, and checking they open, close and lock correctly.
The wet room and its plumbing
- Confirm before ordering
- What arrives pre-fitted, and the exact water-in and drain connection points and sizes.
- On site
- Connecting water and drain to the site supply, then testing for leaks and correct drainage.
Power through the building
Electrical distribution and lighting are partly pre-wired and partly connected to the site supply by a qualified electrician.
- Confirm before ordering
- What wiring and distribution arrive pre-fitted, and the supply rating the building needs on site.
- On site
- Connecting to the site supply, then testing circuits and completing the local electrical certification your destination requires.
Cooling and ventilation
Air-conditioning is where the comfort of a hot-climate site is decided. The unit, its power supply and its condensate drain all have to line up.
- Confirm before ordering
- Whether the unit is included or client-supplied, and the electrical and condensate-drain interface needed.
- On site
- Mounting and connecting the unit, then routing power and condensate drain to the correct points.
- Confirm before ordering

What you stand on and its underside
The finished floor carries people, furniture and equipment. Its make-up affects stiffness, comfort and how the building sits on its base.
- Confirm before ordering

The lid that takes weather and sun
The roof sheds rain, carries wind load and — in hot climates — takes the most solar gain, so its build and the joint sealing matter.
- Confirm before ordering
- Roof construction, insulation, and how the roof-to-wall joint is waterproofed and fixed.
- On site
- Check and make good the roof joints after assembly, and confirm any site-applied sealing or trim.
The enclosure that keeps heat in or out
- Confirm before ordering
- Panel type and core, insulation, fire-test reports that match the actual model, and waterproofing at joints and openings.
- On site
- Assembly and sealing of the wall panels and openings, made good to the delivery plan.
Openings that balance light and security
Windows and doors are where comfort, security and cost meet. They are usually configurable, but very large or structural openings may need a factory review first.
- Confirm before ordering
- Glass type and frame, door hardware and locking, and whether any opening you want changes the structure (that needs factory confirmation).
- On site
- Final fitting, flashing and sealing of openings once the envelope is assembled.
Everything pre-fitted versus connected on site
- Confirm before ordering
- Exactly what arrives pre-fitted versus site-connected, and the interfaces for any air-conditioning, heating, solar or kitchen equipment you want.
- On site
- Final connections to site power, water and drainage and testing — and whose scope that is.

See what arrives on site
A finished-looking product photo is not the same as what arrives at your gate. Drag the marker along the track to move through factory prep, shipping, arrival and the work that still happens on site.
The exact split between pre-assembled and flat/dismantled delivery depends on the model and route — always confirmed per order.

What is included in your quotation
A quotation should be transparent enough to compare against another supplier fairly. These four buckets show how MODARVEN splits supply, options, local work and things still to confirm — so you can ask any supplier the same way.
Proposed supply
The base buildings and their core structure — the units themselves, in the configuration stated in the written quotation.
- Base models and their primary structure
- Standard configuration as listed per model
- Packaging for the agreed shipping method
Optional / separately quoted
Items offered on top of the base, quoted separately so you can see what each one costs.
- Finishes, flooring and furniture upgrades
- Solar, lighting, kitchen or bathroom packages
- On-site technician support (time and travel, agreed separately)
Local site work
Work that typically happens on your side of the delivery — normally arranged and paid for by you.
- Foundation and site preparation
- Offloading and lifting
- Assembly, fit-out, utility connections and testing
- Local permits and approvals
Needs confirmation
Everything that depends on the specific project and is confirmed in writing before you commit.
- Customisation outside the confirmed base and options
- Exact delivery address, route and country requirements
- Taxes, duties and import documents
- Compatibility of any equipment you want to source yourself
These are proposed boundaries, not confirmed contract terms. Your written quotation and contract are the only record of what is in and out of scope.
Build your purchase intent
Drag the items you are considering into “My list”. Items involving integration (doors, windows, bathroom, air-conditioning, kitchen equipment, lighting, solar) stay flagged for a compatibility check — they don’t become technical commitments just because you list them.

Questions buyers keep asking
The real obstacles people hit, answered plainly.
Is MODARVEN the factory?
No. You contract with MODARVEN, and MODARVEN sources from its partner factory in Guangdong, China. MODARVEN coordinates configuration, production, export and delivery; the factory handles the agreed production and technical support.
Will the building arrive ready to use?
Not necessarily. Space capsules are often shipped dismantled or in sections and assembled/finished locally; container cabins may ship whole or flat, confirmed per order. Foundation, offloading, assembly, utility connections and local approvals are typically your side to arrange.
Can I change the size or layout freely?
Customisation is limited to the factory’s confirmed base models and options list. Anything outside that is assessed by the factory before it can be quoted — not promised on the spot.
How much does a unit cost, and how long until delivery?
We don’t publish fixed prices or lead times because they depend on configuration, quantity, destination and current factory schedule. Every order is quoted in writing with the scope and terms stated.
What documents will I receive?
Drawings, installation guidance and remote support are part of the normal handover. Certificates and test reports are discussed per order because what you need depends on the destination and use — we’ll confirm what is available for your specific model rather than assume.
Can you deliver to the UK or Saudi Arabia?
We have coordination contacts for customs clearance and delivery in both countries. The exact address and order scope still need to be confirmed per project.
