Frequently Asked Questions

How much does a modular building cost?

The cost depends on your requirements for your unique modular space. We have different modular solutions available for purchase and rent, and the prices vary depending on your need. Fill in the enquiry form here, and our team will be in touch to conduct an in-depth personal consultation.

Are modular solutions expensive?

They don’t have to be. Depending on your needs, selecting the right modular products for rental or purchase is a low-risk, high-value investment.

For modular solutions on rental, the initial investment is lower than buying. However, it only becomes non-cost effective if the duration of usage is undecided and gets stretched on a month-to-month basis. When renting a modular space, it’s essential to have a clear idea of the exact usage purpose and duration to compare the cost and affordability of purchasing the modular space.

For modular solutions that are purchased, it becomes more cost-effective for long-term usage. Because of its durability, strength and higher customisability , it can serve as a long-term solution for brands that foresee the usage duration to be anywhere from 2 to 20 years.

Sankyo Frontier’s wide range of modular products allows you to find the best solutions to your needs. From the CT-J basic series to the Gorilla series, our modular spaces give you great flexibility and choice for industrial, residential or commercial purposes.

How long do modular buildings last?

We have segmented our modular products to fit two modes of use — rental or purchase.

In general, modular buildings are extremely durable and fit for long-term use for up to 20 years. Read our case studies to find out how versatile our products can fit into both the commercial, industrial and residential needs of users across the globe.

What is the floor load capacity of the modular products?

Most of our products, such as the MS1 and CT-J units, can withstand up to 295kg/m2. If you have a specific project you’re exploring for our modular solutions, drop us an enquiry and our team will be in touch to conduct an in-depth personal consultation.

What materials are used to produce Sankyo Frontier’s modular units?

Each of our modular units is constructed with lightweight steel, coloured steel plate walls, and plywood. All units are also insulated with styrene foam and moisture-proof sheets to ensure the buildings are weather-proof. All units are designed to be easily transported, assembled and dismantled with reusable materials. Only a simple crane and a small team are needed to assemble the prefabricated modular units on site.

Our MS-1 series, for example, is also 25% more rigid and 16% stronger than conventional modular products that you find on the market. Learn all about the MS-1 series here.

What is the difference between our modular units versus commercial shipping containers?

Our modular units are superior to shipping containers in three key aspects: Safety, Customisation, Convenience. Our modular units are safe and built to withstand harsh elements and comply with Japanese building regulations, which have some of the strictest building codes in the world. No extensive modifications need to be carried out to ensure the safety of the occupants within the unit. Furthermore, our units also have electrical wiring and lamps pre-installed, which reduces time spent to custom-fix wiring and fixtures compared to shipping containers that come bare-bodied.

How can I customise my modular space?

To fit your project’s brand guidelines and needs, we offer options to modify building features like staircases, wall panels, facilities, and modular building exteriors and interiors.

For more details on making a modular space uniquely yours, fill in our enquiry form for a personal consultation with our team.

Check out our past case studies of modular solutions that we’ve provided our satisfied clients over the years.

Do the modular products come in fixed dimensions?

Yes, our modular products come in fixed dimensions, but you can stack them horizontally or connect them vertically for bigger space needs. If you have a specific land space dimension limitation, chat with our friendly team to get a detailed personal consultation.

What is the extent of customisation I can make?

The extent of customisations will depend on whether the modular space is a rental or purchased. Generally, purchased modular spaces can have a greater degree of customisation, whereas rented modular spaces have more limited customisation.

For more details on customising a modular space that is uniquely yours, fill in our enquiry form for a personal consultation with our team.

You can also check out our past case studies of modular solutions that we’ve provided our satisfied clients over the years.

How long does it take to build a modular building?

Our modular units are designed for easy assembly, and we can build about eight units in a day. Furthermore, as almost all assembly processes occur in our factories, our modular buildings require little on-site construction time. It is also safer and reduces unnecessary potential on-site injuries. For more details, please write to us via the enquiry form.

What are the processes involved in building a modular building?

Multiple layers of decision-making, logistical requirements and planning are needed to erect the desired modular space.

A robust modular building design involves precise design specifications, safety and regulation clearances, permissions from the authorities, site preparation, transportation of the unit modules and installation. Sankyo Frontier designs modular solutions so that most of the heavy lifting (preassembly) occurs in our factories. They are then transported, assembled and installed safely using a simple crane alongside the support of a small team for supervision.
