Top 7 Construction Companies In Bangkok

Top 7 Construction Companies in Bangkok

Reputation

We choose construction businesses with a trustworthy and honest reputation to ensure the quality of work.

Expertise

This is a crucial factor to consider because construction firms with extensive backgrounds and years of experience may have a large list of completed projects to back up their claims.

Service

We included businesses that are experts in their field and have competent employees. Also, we took into account how quickly each construction company delivered projects and their service quality must match the amount spent.

Safety

Their track record of safety compliance was another factor we examined to narrow down our list of potential construction businesses.

Pros

  • Has over 10 years of experience
  • Offers free consultation
  • Provides full package (architecture, interior design, construction)

Cons

  • Doesn’t have social media presence

Delcoi can provide you with services anywhere in Bangkok, whether you want to renovate your house, convert a space, or build a store.

Notably, Delcoi was established by a group of interior design professionals. Over the past ten years, it has developed a solid reputation in Bangkok, which we find really impressive. 

Additionally, it has demonstrated its expertise by giving clients top-notch work. For instance, we noticed how its interior design team creates unique designs that transform any space’s essence into an iconic and useful layout.

We also believe that Delcoi stands out because of its friendly approach. It strives to provide as much information as it can while communicating with customers in a very friendly and conversational manner.

We also find it convenient that it even has a very informative FAQ section on its website, where customers can learn more about the business to aid in decision-making.

After consulting with Delcoi, we were able to appreciate that it offers comprehensive samples or visuals during the initial meeting. 

We also think it’s noteworthy that Delcoi successfully brings customers’ visions to life, according to clients we spoke with. They mentioned that they were impressed about the quality of Decoi’s construction and interior design services.

Many of them also value that their contractor kept them informed as the project moved forward, from the installation of floors, walls, and ceilings to the installation of electrical systems, plumbing, and air conditioning.

Overall, we think the expertise of Delcoi’s staff is especially useful for customers who are unsure of what style will suit them or who have no prior experience with simple home improvements, like painting, simple interior design, or architecture.

On the other hand, it’s quite disappointing that prospective customers will be unable to conduct extensive research on Delcoi ahead of time. 

It doesn’t have a social media presence, which we believe is essential in this day and age to draw in and maintain customers.

Pros

  • Caters to several projects
  • Skilled and accommodating staff
  • Has over 55 years of experience
  • Has extensive portfolio

Cons

  • Poor online customer service
  • Lacking information on website

C.E.S. Co., Ltd. primarily focuses on residential construction and renovations, but they also serve commercial projects such as resorts, malls, and hotels. We think it’s remarkable that they are well-known for their excellent conceptualization abilities.

To begin with, its portfolio consists of buildings like warehouses, shopping centres, colleges, offices, residences, and even industrial ones.

Our survey revealed that their crew was very punctual and accommodating. Other clients also reported that the team was able to stick to the project’s timeline.

Furthermore, we also discovered that they have been in the industry for over 55 years. Since the majority of clients rely on the contractor’s dependability and trustworthiness, we consider this to be an impressive feature.

We also appreciate C.E.S. for delivering excellent finished products. According to our research, all of their former customers were pleased with their service.

However, when we reached out to C.E.S. and requested a quote, we were disappointed when we didn’t get one after using their website. This disappointed us because we understand that some clients would prefer a hassle-free quote process.

Another issue we had with C.E.S. was how difficult it was to search for the services they provide. Their website does not provide enough information about this, and we find it difficult to read through their website.

Despite its setbacks, we are pleased with its portfolio because it lines up with our findings and the reviews of previous clients.

Pros

  • Caters to several projects
  • Provides wide range of construction services
  • Skilled and accommodating staff
  • Has 60 years of experience
  • Has extensive portfolio
  • Has several certifications and safety awards

Cons

  • Expensive

Full-phase construction projects might seem intimidating. However, with Thai Nishimatsu’s knowledge, we think clients can more simply move through each stage, from planning to construction.

In our books, a company’s many years of experience can be a reliable sign of the calibre of its services. Furthermore, this assures customers that the company they’re collaborating with has gained ample knowledge over the years.

Impressively, Thai Nishimatsu has been in business for nearly 60 years and has earned the respect of its clients. All of the recent clients we spoke with about Thai Nishimatsu expressed satisfaction with their service.

Our favourite among their services is the Turnkey Project construction. We think this particular service works best when you want one business to handle both the designing and building processes.

Because of this, we think it’s impressive that Thai Nishimatsu can handle anything, from offering early pre-construction services to finding the best prices for long-lead items.

We especially like that they work on a variety of projects, including civil, industrial, commercial, and residential ones, all of which are viewable on their website. 

Another feature that we think is noteworthy is they clearly feature their certifications and awards. We believe that this has a significant effect on assuring their clients of the calibre of their service.

However, quality projects can be costly, so clients on a tight budget may want to reconsider hiring them.

Although we did not have access to their pricing, several former clients we spoke with claimed that they were expensive.

In addition, we believe Thai Nishimatsu is a fantastic choice for a construction company due to its extensive portfolio, successful track record, and certifications.

Pros

  • Offers interior design and construction
  • High quality designs
  • Has flexibility in working with client’s budget and timeline

Cons

  • Limited constructions service
  • Lack information on certifications
  • Limited information on website
  • Poor online customer service

Compared to the other entries on this list, B-complete Construction Co., Ltd. only entertains residential builds. They mainly focus on luxury home projects all over Bangkok.

Overall, we think B-complete is an excellent option for a construction company, since they offer services ranging from interior development to building. 

Although they are primarily limited to residential projects, we like that they cover all phases of construction.

Former customers we spoke with have praised B-complete, applauding its dependability and professionalism from the beginning to the end of projects. 

It’s also worth highlighting that customers appreciate them for their open communications, transparent quotes, and knowledgeable advice.

Another thing we value is their flexibility in working within a range of financial and time restraints. 

From our surveys, we noted that previous customers who had specified a wide range of restrictions and spending caps claimed that B-complete still met their needs.

We also commend B-complete for being accessible for consultations so that you can voice your concerns. However, it’s disappointing that they frequently take longer to reply than we anticipated.

Moreover, while B-complete is affiliated with Seacon Group, we’re a bit downcast that it does not disclose any information about its CIDB ratings or ISO certifications.

Furthermore, it’s somewhat disappointing how limited their website information is. You can only call them if you want an estimate or consultation because there is no online form for those requests.

Nonetheless, because of B-complete’s dependability and expertise, we still think they’re one of the best construction companies in Bangkok.

Pros

  • Provides wide range of construction services
  • Knowledgeable staff
  • Utilises modern equipment
  • Fast turnaround
  • Exhibits pricing transparency

Cons

  • Poor online customer service
  • Only accepts big projects

Syntec Construction is a general contractor that specialises in the construction and development of commercial property, residential property, and public-private partnership (PPP) projects.

They put a lot of emphasis on finding the newest, most effective tools, technology, and machinery for the construction industry, which we think is great because it guarantees that each project will be completed efficiently.

One of the things we appreciate most about Syntec Construction is its ability to complete substantial renovations in such a short period of time. 

From what we’ve seen, Syntec’s team’s meticulous attention to detail in their proposal and plans is the reason the process moves along without any hiccups.

We also value its commitment to complete transparency. 

Every client wants to know how much something will cost so they can determine whether their money is being used effectively for what they want—and we appreciate that Syntec is very transparent with this information!

Additionally, we admire that Syntec Corporation provides its clients with services that are quick and convenient. It offers fixed-price contracts to those with tight budgets, so you don’t have to worry about going overboard.

However, we think it’s a bit disappointing that it only takes on large projects.

Additionally, we have some reservations about their customer service. A crucial component of a company’s culture is a prompt response to calls and emails, which we did not experience with Syntec.

Pros

  • Specialises in engineering workforce
  • Knowledgeable staff
  • Aidsin speeding up paperwork process
  • Prioritises safety
  • Has 37 years of experience

Cons

  • Poor online customer service

If you’re looking for a construction company that focuses on engineering workforces, Thai Semcon is worth checking out. It offers electrical, mechanical, communication, and plant and machinery installation for over 37 years.

We especially appreciate that they are easy to talk to and that closing the deal won’t be difficult.

The first quality of their service we appreciate is their capacity to quickly complete tasks. We believe it has to do with how the team sets up everything so that construction just goes smoothly when it comes time to execute.

We also value Thai Semcon’s professionalism. Aside from the staff being cordial and accommodating to their customers, their level of concentration and discipline also demonstrates their depth of knowledge in the construction sector.

In addition, involving multiple documents, such as licences or permits, causes paperwork to take a while. However, Thai Semcon expedites the process and makes things easier for everyone, which is remarkable!

They also place a high value on safety, which is another quality worth noting. They hold regular meetings, patrols, orientations, and even safety award presentations to motivate each team.

Moreover, Thai Semcon has received numerous accolades and certifications for its safety management, which is a huge plus in our books!

We are, however, a little frustrated by their online customer service’s slow response time. You must wait a few days to hear back from them.

Pros

  • Has 49 years of experience
  • Offer a wide range of services
  • Has creative and skilled staff
  • Has extensive portfolio
  • Has several certifications

Cons

  • Poor online customer service
  • Lack information about rates

Over the past 49 years, Thai Obayashi has been involved in several projects. What stood out for us is they have a clear concept for construction and design, right from the start of planning.

Thai Obayashi has established a reputation in the construction sector through its work with numerous brands, businesses, and corporations—which is impressive! 

We also think that its online portfolio is well-organised and shows the variety of projects Obayashi can handle. 

Also, it’s worth noting that Thai Obayashi is a top construction company in Bangkok because of its constantly evolving offerings. We like that it provides a full range of construction services, from consultation to post-construction and even renovation.

Another thing that impressed us about Thai Obayashi is that working with them is a great experience. Many of their clients we spoke with applauded its team’s creativity and willingness to go above and beyond to satisfy their vision.

We also appreciate that the team is professional, skilled, and knowledgeable. According to our surveys, clients felt assured since Obayashi can take on complicated tasks in construction and planning.  

Unfortunately, we believe Thai Obayashi can work on its customer service, especially the response time of its staff. We noted that they are slow to respond to inquiries, which is something we’re iffy about.
