To Buy or Not to Buy: The 5 Pros and Cons of Prefab Homes

The market for prefabricated (or prefab) homes has grown a lot over the last few years. In fact, it’s grown by 8.5 percent and is on track to become an $11 billion industry by the end of .

With competitive price and timely delivery, Hongyu Dinghao sincerely hope to be your supplier and partner.

Have you been considering buying a prefab house? Do you want to learn more about them before you take the plunge?

If you answered “yes” to any of these questions, read on. Explained below is all the information you need to know about the pros and cons of prefab homes.

What are Prefab Homes?

Let’s start with the basics. The prefab home market may be growing, but a lot of people still aren’t 100 percent sure what these homes are.

In simplest terms, a prefab home is a house that was built in sections inside of a special home-building facility. The sections then get moved to a home site, where they’re assembled and prepared for the homeowner to move in.

Prefab homes are built in a unique way but, like traditional homes, they must meet basic requirements put in place by the Department of Housing and Urban Development. These requirements cover things like strength, durability, energy efficiency, and fire resistance.

Pros of Prefab Homes

There are plenty of reasons why you might want to consider buying and living in a prefab home. The following are five of the greatest benefits they have to offer:

1. More Affordable

Many people are turning to the prefab home trend these days because it provides them with an opportunity to save money while still becoming homeowners.

In general, prefab homes are much more affordable than traditional houses. They use fewer materials, and the process of determining how much is needed is much more precise, so you don’t have to worry about paying for materials that don’t end up getting used.

There are fewer labor costs, too, since prefab houses don’t need as many people on-site to put them together.

2. Increased Energy Efficiency

In many ways, prefab homes are better for the environment than traditional homes, too. These homes are airtight and designed to minimize energy loss as much as possible.

These days, lots of manufacturers are taking extra steps to make their homes more energy-efficient. For example, they’re adding solar panels and rainwater catchment systems.

3. Fast Construction

If you’ve ever built a house before (or know someone who has), you know that it’s almost impossible to get the thing built on schedule.

Even if no major emergencies happen, things like the weather or slowed down deliveries can drag out your building time and make it harder for you to move in when you want to.

With prefab houses, the construction process is much faster and much more precise. As a result, you get in sooner.

4. Minimal Waste

With traditional houses, it’s normal to have a lot of materials left over that often end up in a landfill somewhere.

With prefab houses, there’s virtually no waste. Because they’re built in factories, any leftover material gets recycled and used to create another house. This is another example of the way that prefab homes can benefit the environment.

5. Healthier

Finally, prefab homes have the potential to be healthier than traditional homes.

Think about it. When you’re building a house on a building site, it’s going to be exposed to the elements, including a lot of moisture.

This, in turn, can contribute to mold growth. Mold exposure can cause serious health issues in some people and can even be life-threatening in some instances.

Prefab homes don’t totally eliminate the risk of mold exposure, but they do reduce it in a significant way.

Cons of Prefab Homes

In addition to these great benefits, prefab homes do come with some drawbacks. Here are five cons to keep in mind as well:

1. Potential Assembly Problems

It’s important to have a trained and experienced contractor on your team when assembling your prefab home.

Without their knowledge, it’s possible that your home could be assembled incorrectly. This, in turn, could lead to potential damage, shorten its lifespan, or minimize its energy efficiency.

As long as you’re working with the right contractor, though, the risk of this happening is quite small.

2. Potential Transportation Problems

You may also run into problems having the pieces of your house transported to the building site. It can get expensive as well if you are building in a rural area.

3. High Land Prices

Depending on where you plan to build your home, you could be strapped with high land prices.

Depending on the price of your home, this might not be a big deal, and you might be willing to make the trade-off. Be sure to consider all the variables that will affect the final cost of your house, though.

4. High Utility Hookup Costs

Speaking of variables, you also ought to consider the cost of utility hookups. If you’re building in a rural area, for example, you may have to pay more money than you’d like to get your utilities set up before you move in.

5. Less Customization

In some cases, you don’t have as many customization options when designing a prefab home. You usually have a set number of options to choose from, and it can be hard to find exactly what you want without having to pay extra money for something special.

There’s still a lot of variety among these houses, though, and the other benefits prefab homes bring to the table, such as longer lifespans and better energy efficiency, are worth the sacrifice to most people.

You Know the Pros and Cons of Prefab Homes: Now What?

Clearly, there are both pros and cons of prefab homes. Now that you know more about these pros and cons, you can make an informed decision for yourself.

Remember, there’s no one correct answer here. Think about your lifestyle, your budget, and your preferences to decide whether or not a prefab home is a good fit for you and your family.

9 Things to Know About Prefabs Before You Buy - Dwellito

Despite prefab homes becoming an increasingly popular option for many people, there is still a surprising amount of misinformation about what they are, how they are built and the many benefits they can provide.

We’ve decided to set the record straight by listing 9 things you need to know about prefabs.

1. What is prefab construction?

Prefab (or prefabricated to give it the formal name) construction is essentially the building of a home (or building) using materials that have been manufactured in panels or sections. Think of these as Lego-style building blocks that can be assembled in a much shorter space of time. Sometimes the entire prefab is built at the factory before being transported ready to be positioned into place at the find destination.

This is far from a new idea, as prefab homes have existed since the early part of the 20th century. In some cases (not always) they can be a very cost effective option that reduces labor overheads, while also increasing safety parameters along with the time taken to build a new home.  

2. On-site versus off-site construction?

There is no right or wrong answer to this question as it will come down to personal needs, which are typically dictated by the time line you are working to and available budget.

Firstly, we’ll explain the difference between the two options. On-site construction is the more traditional type most people are familiar with. This is where the various components are manufactured and delivered to the end destination where the prefab will be built and secured into place. The parts arrive flat-packed and ready for construction either by yourself or with a qualified builder. However, rather than using traditional stick framing construction methods, panels are used instead.

Off-site construction refers to the pre-assembly of the house in a self-contained environment, usually a factory. This can offer advantages such as higher standards of engineering and less impact from weather conditions, with the overall project likely to have fewer setbacks and as a result the outcome becomes more predictable.

If the factory does not have license certification to complete the full build, not all of the prefab can be completed off-site as city inspectors need to ensure it meets legal requirements. In many cases anywhere between 40-90% of the build can be finished before being delivered.

Having a prefab built off-site will mean it is completed on time, on budget and exactly to spec. The mass production of prefab materials that are constructed in a factory allows the manufacturer to have tighter control in terms of managing costs. This enables them to set fixed prices and deadlines, which is attractive to customers working to a particular budget and time line.  

The same can be achieved on-site, although it will depend on the skills and time available to ensure the various construction targets are met. Of course, not everyone is in a hurry to complete the build, so building on-site gives you more control and could end up being a cheaper option in the long-run.

3. When to go with prefab?

The benefits of going with a prefab home may not be immediately clear before you do some research. The most important points to consider are:

  • Shorter build time: In most cases a brand new prefab home can be constructed in a matter of weeks rather than the 6-12 months it takes for a traditional home. This applies to both on and off-site construction, so if you are in a hurry to move in you won’t have to wait too long. It also means not having to suffer a year – or more - of builders constantly coming and going from the site.
  • Predictability: From the very start of the project you’ll know how much it is going to cost and when it will be completed, making it easier to manage and organize everything else around the build. In comparison, traditional builds rarely meet the initial deadline, adding significantly to costs.
  • Less stress: If you choose to build it off-site, many prefab companies provide a service that will do the hard labor for you. This comes at an extra cost but it guarantees a high quality build and much less stress and worry. And if you build off-site there will be no delays caused by adverse weather conditions.
  • Rental income: Building an accessory dwelling unit (ADU) can also be done on your existing land, affording you potential rental opportunities in a short space of time.  

4. What parts are customizable for prefab?

Many providers will sell packages that are of fixed dimension so you know exactly what you will receive with a templated floorplan, allowing for some modifications in the interior such as flooring and fixtures. While there are others (typically at the luxury end of the market) that will allow you to create a bespoke prefab house from scratch.

5. Is building prefab a good investment?

In order to understand if a prefab is a good investment for you, there a number of factors to consider.

While they dramatically cut down the construction time and give you a clear idea of how much it will cost to complete, the long-term ROI (return on investment) largely depends on the conditions involved with the sale.

For example, at minimum, the amount of money spent on building the prefab need to be recouped when it is sold. Of course, while there is no way of knowing exactly how much the property will sell for in the future, researching the local property market will give you a strong indication. This is especially true if you plan on living in the prefab for a few years before putting it on the market.  

Similar to traditionally built properties, prefab homes appreciate in value the longer you remain the owner. Understanding the local property market over the past 5-10 years will tell you whether prices are increasing and how much potential there is to make a good profit on a sale.  

The same principle also applies to the rental market. If you are thinking of building a prefab to rent it out for extra income, you can get a good idea of the monthly/yearly yield you can enjoy by comparing against similar-sized rental properties.

Aside from sale and rental values, prefabs are also very environmentally friendly, not just in terms of the lower carbon footprint produced during construction, but also in an ongoing capacity, helping to reduce energy bills for the long-term due to the insulation properties.  

6. Are prefabs modular homes?

While it may appear that prefab homes are the same as modular homes, there are some distinct differences between the two.

Prefab homes are based on the idea of manufacturing key structural elements before either constructing them at the factory and transporting it to the final location, or delivering the separate parts to the site before it is put together.

Modular homes are always built in a factory setting and never subjected to weather conditions before construction and delivery. There is no option to order the parts and have them delivered separately. This is a more costly option and doesn’t provide customers the potentially cheaper option of building the home themselves.

7. Are prefab homes safe?

There is a perception that prefab homes are not as safe as traditional properties due to the alternative construction methods involved. However, this is certainly not the case for a number of reasons.

Firstly, prefab homes have to be constructed to meet strict building code regulations, supported by regular on-site inspections at every stage. This is more stringent than site-built homes which only require a single inspection. Another reason prefab homes are a safe option is due to the manufacturing process. They are constructed in a controlled environment using equipment specifically designed to reinforce the structure for long-term usage. Traditional contractors do not have access to this sort of equipment when building a home on-site.

8. How long do prefab houses last?

Just because prefab houses are not made in the same way as traditional homes it doesn’t mean they are not as safe to live in. But, of course, any sensible home buyer will want to know they are getting value for money before making a commitment.

As with building any type of property, how long it will last will depend on a number of factors. The quality of materials used play a big role, as this will dictate how well it can withstand general wear and tear and external elements.

How the prefab home is constructed will also play a significant role in how long it will last. The more skilled and experienced the people involved with building it are, the more assurance you will have that it will stand up to the rigors of time.  

Also remember that building a traditional home means the materials are exposed to the elements from the very beginning of the process, while the sections of a prefab house are made within the four walls of a factory affording them better protection.

When it comes to the delivery of a prefab, because they have to be shipped in modules, the material needs to be robust enough to withstand the issues that can arise with lengthy transportation. In order to achieve this, the manufacturing process ensures the material is often a lot more reliable than those used with traditional stick methods.

9. What are prefab houses made of?

The construction of a prefab home relies on using many of the same materials associated with a traditional home. The most common being wood, steel and concrete. Of course, each manufacturer will rely on a different set of materials to suit the specifications of the build, with cost and efficiency usually being the deciding factors. Most importantly, for anyone thinking of building a prefab home, you can rest assured that the sturdiness of the materials will be comparable to anything used in a traditional home.

Should I buy a prefab home?

Where once it was thought that buying a prefab home would mean a drop in quality, that is no longer the case. Modern prefab packages offer greater flexibility, fixed costs and deadlines, as well as providing substantial environmental benefits.

They are made from materials that can withstand the natural elements and the ongoing wear and tear that comes with day-to-day living. If you want to build a home that is long-lasting, adaptable and can work within your set budget, then investing in a prefab home should be your next move.
