No More Project Nightmares with the 5 Best General Contractors in Bangkok
Just recently, a relative of mine got married and wanted to upgrade their home—make it more spacious, fresh, and well, less like a single person’s apartment. But since they were first-timers with renovations, they had no clue where to start. Going in blind and winging it? Not an option.
So, they met with a general contractor who handled everything from design to construction. Their biggest challenge? Deciding between eggshell white and cream white for walls.
It got me thinking—general contractors are basically lifesavers when it comes to home projects, renovations, or even big commercial builds. To save you the trouble, we reviewed the best general contractors in Bangkok so you can find the perfect team for your next project!

Delcoi Interior Design and Renovation basically handles every aspect of a project, from initial concept and design to completion. We like that this means you’ll only have a single point of contact, simplifying communication and coordination.
Their experience is also pretty diverse—think residential homes, commercial offices, retail shops, and hospitality venues. This flexibility shows that they can craft customized solutions to fit any project, big or small.
Another aspect worth highlighting is that Delcoi brings together designers, architects, and construction pros to create a dream team for your project. With everyone under one roof, the process and monitoring flow smoothly, saving you from all the stress of running around.
We also appreciate that their services include 3D renderings of your final interior design, giving you a realistic preview of how the project will turn out—it sparks some excitement, too.
That said, their pricing can also come off as premium for others, especially if you compare it to smaller firms. Still, given their comprehensive services and in-house expertise, Delcoi is worth the investment.
Committed to time and quality of work
“Outstanding. Our family is very pleased with their interior services and designing concepts used in our home. Their designers are very experienced and committed to time and quality of work. Thanks to Delcoi team for the amazing service.”

We’re impressed at Patrasangthong’s knack for managing projects ranging from small-scale shop fit-outs costing a few hundred thousand Baht to large-scale resort developments valued at up to 50 million Baht. In other words, they work well with different client needs and budgets.
Their in-house furniture workshop is a standout for us. You can opt for customized furniture to tie in well with your interior design, keeping a consistent quality and overall look throughout the entire project.
Speaking of interior design—we noticed that their team specializes in high-end work, which is ideal if you’re looking for premium finishes and designs. The clients we talked to also shared their satisfaction with the craftsmanship and product quality.
Just a heads-up, though: they often juggle multiple projects, and there can be times when they’re fully booked and can’t take on new work right away. They’re also closed on weekends, so if you’re on a tight schedule, it’s best to discuss their availability first.
Nonetheless, their popularity just says a lot about their good reputation and success as general contractors.
They are all professionals
“They are all professional. The Owner is not greedy. They give you reasonable price with top quality materials.”

HD Renovations Co Ltd specializes in residential projects, from pre-purchase advice and full-scale renovations to interior design and home staging.
On that note, we like that they offer home staging since it boosts your chances to sell or rent out a place. This makes them an ideal choice for landlords who are renovating fixer-uppers and planning to put them out on the market—it’s a one-stop shop.
From our surveys, the team and contractors behind HD Renovations have incredible work ethics and professionalism. Besides keeping regular communication with their clients, we noted how they regularly check the workers on site and the progression every day.
And thanks to their consistent monitoring, they can catch and fix issues right away, keeping your project on track. This approach makes sure that everything goes smoothly, so you won’t have to worry about unexpected headaches as the project wraps up.
However, it’s a bummer that they don’t focus on commercial projects. Regardless, if you’re looking to renovate your place, HD Renovations is a solid choice.
Excellent monitoring
“Arnaud and his team at HD renovations deliver high quality and are a pleasure to work with, they completely renovated an apartment for us including the reconstruction of new walls, ceilings, floors, windows, kitchen and bathrooms and we can highly recommend them. Arnaud is always willing to think with you on options for lay out. Excellent monitoring / communication of progress and costs with regular updates as well.”
Angelique Van Spijk, Google Review
Quality work and great team
“It’s not easy to find a right contractor especially in Bangkok or Thailand in general. HD Renovation is reliable, great quality work and great team. Everyone of their staffs really care about their renovation work. When mistakes or unexpected result happened, they really tried to fix it and catered the best result. They have done amazing job. I would recommend to anyone who wants to renovate.”

B-complete Construction is a reliable choice if you’re planning on a luxury residential project and want a team that knows what they’re doing—like being familiar with handling high-end designs and products.
Their expertise in this niche market gives them the edge to deliver tailored and well-versed solutions that meet the specific demands of luxury homeowners.
You can expect end-to-end services with their company, from design to construction. It’s also neat that they provide standard house designs that can be adjusted to fit the client’s land and preferences.
We also have to give their interior and design team a shoutout for ensuring functional and visual coherence with every project. They put different elements together without making them look out of place.
While their standard designs can be tweaked, they might fall short if you’re after something really unique and one-of-a-kind. But hey, B-complete Construction’s experience, comprehensive offerings, and expertise with luxury make them worth considering.

PipeDreamDeco Interior Design Bangkok provides end-to-end services, which include interior design, construction, and project management. We like this approach since you’re basically just working with a single team throughout the entire project—easier communication and execution.
We love that they have a bilingual team—it’s been a game-changer for clients who don’t speak Thai, making it easy to share ideas and understand recommendations. It’s also a plus that they always maintain regular communication, keeping you informed and involved in decision-making.
It’s also worth noting that they have an impressive portfolio. They worked on designing and constructing spaces like hotels, offices, and homes—demonstrating the versatility and presence they have in the industry.
The catch? Their rates and pricing are on the higher side. We found that their interior designs can range between ฿ 1,000 to ฿ 2,000 per sq.m, ฿ 10,000 to ฿ 35,000 per sq.m for construction cost, and 10% to 15% of total construction cost for project management.
On the bright side, these services have comprehensive inclusions and offerings, so you’ll be getting your money’s worth with PipeDreamDeco Interior Design Bangkok.
Fast and efficient process
“I highly recommend this interior design and construction company for office projects. They flawlessly handled the design and construction of our 300 sqm Grade A office space in central Bangkok, completing it in an impressive 3 months. Their commitment to punctuality ensured a fast and efficient process. Additionally, they assisted in adhering to the budget requirements, demonstrating exceptional financial responsibility.”
