Pros and Cons of Dongas: Everything To Know About Perth’s Best Space-Saving Secret

If you’ve ever considered flexible and affordable accommodation solutions, dongas might have caught your eye. 

These portable buildings are becoming increasingly popular across Perth for various uses, including temporary housing, site offices, and even customised living spaces. But are they the right solution for you?

The growing interest in dongas stems from their versatility and cost-effectiveness. Whether you’re in the mining industry, need additional space for a business, or want a quick, convenient housing option, these units seem like an ideal choice. 

However, like any solution, they have their advantages and disadvantages.

By the end of this handy guide, you’ll have a clear understanding of whether these modular buildings meet your needs and what to consider when making your final decision.

They are prefabricated structures designed for temporary or semi-permanent use. 

Originally developed to serve industries like mining and construction, where on-site housing and offices are essential, these modular buildings have since evolved into versatile solutions for a wide range of applications.

In Perth, they have become a sought-after choice for businesses, homeowners, and event organisers alike. Their ability to be customised, transported, and installed quickly makes them an attractive alternative to traditional building methods. 

From site offices on construction sites to pop-up classrooms, temporary accommodations, or even personal studio spaces, these portable buildings offer flexibility that is hard to match. What sets them apart is their practicality. 

They often come equipped with basic amenities such as electrical wiring, plumbing, and insulation, ensuring they’re functional and comfortable right from the start. Additionally, their modular nature allows for easy expansion or modification to suit.

✓ Cost-Effectiveness

One of the most significant advantages is their affordability. Traditional construction projects can be expensive, with costs for materials, labour, and time adding up quickly. 

Being pre-fabricated and mass-produced, these portable accommodations dramatically reduce these expenses.

In Perth, the average cost to construct a new building can range from $1,500 to $2,500 per square metre. In contrast, modular buildings often come at a fraction of that cost, making them a budget-friendly option for businesses and individuals. 

This cost-saving potential is particularly appealing for industries like mining and construction, where budgets can be tight, and temporary solutions are preferred.

✓ Quick Installation and Deployment

Time is money, and these portable buildings excel in this area. Unlike traditional construction, which can take months or even years, they are designed for rapid deployment. Once fabricated, they can be delivered and set up within days. 

This makes them ideal for projects requiring immediate accommodations, such as emergency housing or site offices. 

Perth’s construction sector has frequently turned to dongas for this reason, as they allow teams to set up functional spaces without delays, enabling projects to stay on track and on budget.

✓ Versatility and Customisation

They aren’t just one-size-fits-all solutions. They can be tailored to meet a wide range of needs, from simple sleeping quarters to fully equipped office spaces. 

Many suppliers offer add-ons like air conditioning, upgraded insulation, or specific layout designs to match the purpose of the structure.

This versatility has driven their popularity in Perth, where they’re used in applications as diverse as temporary event spaces, classrooms, or even backyard granny flats. 

✓ Mobility and Reusability

Another major benefit is their portability. They can be transported from one location to another with relative ease, which is especially valuable for industries like mining, where work sites frequently change. 

This mobility ensures that a single investment can serve multiple purposes over time.

Moreover, because they’re reusable, they are considered a sustainable option. Instead of demolishing a structure after its purpose is served, they can simply be moved to a new location or repurposed for a different use. 

This contributes to reduced waste and promotes eco-friendly practices.

✓ Durability and Weather Resistance

They are built to endure harsh conditions, making them particularly suitable for Perth’s varied climate. From intense summer heat to sudden rainstorms, they’re designed to provide a comfortable and safe environment. 

Many models come with insulation and durable materials that meet Australian safety and environmental standards.

For instance, portable buildings used in remote mining areas are constructed to withstand extreme weather, ensuring they remain functional and secure regardless of the conditions. 

✓ Minimal Site Disruption

Unlike traditional building projects, which can cause significant noise, debris, and inconvenience to surrounding areas, these portable accommodations require minimal on-site work.

 Since they’re pre-fabricated off-site, the installation process is quick and clean, reducing disruption to neighbours or nearby businesses.

This feature makes them an excellent option in urban areas of Perth, where construction noise and activity can be a major concern for residents and councils.

✗ Limited Longevity for Permanent Use

They are primarily designed for temporary or semi-permanent applications. While they are durable and weather-resistant, their lifespan is generally shorter than that of traditional buildings. 

Over time, exposure to harsh elements can lead to wear and tear, especially if the portable building isn’t properly maintained.

For instance, a well-maintained donga might last 10–15 years, whereas a traditional brick-and-mortar building can easily exceed 50 years. For those seeking a permanent structure, this limited longevity could be a significant drawback.

✗ Restricted Design Options

Although they are customisable to an extent, they don’t offer the same creative freedom as traditional construction. 

Their modular nature means they often have standardised shapes and sizes, which may not suit every aesthetic or functional requirement.

For example, homeowners in Perth who value architectural uniqueness or intricate designs may find these modular buildings lacking in this department. 

This limitation can be particularly noticeable when trying to integrate a donga into a residential or urban setting where visual appeal matters.

✗ Challenges with Local Regulations

In Perth, the use of portable buildings is subject to local council regulations and zoning laws. Securing the necessary permits can sometimes be a complex and time-consuming process. 

Regulations may dictate where dongas can be placed, how they are connected to utilities, and whether they meet specific safety standards. 

Failing to comply with these requirements can result in fines or the need to remove the structure, adding unexpected costs and headaches for users.

✗ Utility Integration Can Be Costly

While many models come with basic amenities, connecting them to utilities like electricity, water, and sewage can be a challenge. Depending on the location, these connections may require significant investment in infrastructure.

For example, if a donga is being installed on a remote site, the cost of running power lines or installing septic systems can quickly add up. These additional expenses might offset the initial cost savings that made these portable accommodations attractive in the first place.

✗ Resale Value is Often Low

Unlike traditional properties, they typically do not appreciate in value over time. In fact, their value may depreciate quickly due to wear and tear or changes in demand. 

For those who may want to resell or repurpose their portable building in the future, this limited resale value could be a disadvantage. Used dongas often sell for 30–50% less than their original purchase price, depending on their condition and features.

Dongas vs. DIY Builds

Ease of Assembly and Timeframe

They are pre-fabricated, meaning they arrive ready to assemble or use. DIY builds, on the other hand, require sourcing materials, creating a design, and performing construction yourself.

While some DIY enthusiasts enjoy the process, it’s often time-consuming and requires a significant level of expertise.

For those who need a quick solution, such as a site office or temporary accommodation, these modular buildings clearly come out on top with their rapid deployment capabilities.

Cost and Budgeting

DIY builds can sometimes be more affordable if you already own tools and materials. However, unexpected costs often arise, such as permits, specialised equipment, or professional help.

These portable buildings provide a predictable, all-in-one cost that’s easier to budget for.

Quality and Durability

DIY builds are as good as the builder’s skill. Poor craftsmanship can result in lower durability and reduced safety, especially in harsh weather. These modular buildings are built to strict Australian standards, ensuring consistent quality and safety.

Dongas vs. Traditional Construction

Time and Convenience

Traditional construction is a lengthy process, often taking months or even years to complete. Dongas, by contrast, can be delivered and installed within days, making them ideal for temporary or urgent needs.

Flexibility and Portability

Once a traditional building is constructed, it is fixed to its location. Dongas, however, are portable, allowing you to relocate or repurpose them as needed. This makes them an attractive option for industries that require frequent site changes.

Cost Comparison

Traditional construction is significantly more expensive. In Perth, traditional buildings can cost upwards of $1,500 per square metre, while modular dongas often cost a fraction of that. For those on a budget, the savings are a major advantage.

Customisation

Traditional construction offers unlimited design possibilities, which is ideal for creating unique, personalised spaces.

Dongas, though customisable, are limited by their modular design. If aesthetics or creative architecture is a priority, traditional construction might be the better option.
