Samurai Asia Editorial Department
Tomas Engineering provides sales of Instant Houses in Thailand. This article introduces an installation case at James 500 City Camp Romklao Lagoon, where the Instant House has been set up. It is gaining attention as a new style of accommodation that combines comfort with a sense of oneness with nature.
A Popular Resort-Style Campsite in Thailand
James 500 City Camp Romklao Lagoon is a resort-style campsite with a tranquil lakeside setting, featuring a café and a variety of outdoor activities. The glamping zone is equipped with portable air-conditioning units, private bathrooms, and offers meal services, barbecues, and Thailand’s popular hotpot-style barbecue “Moo Kata.” Multiple photo spots are also available, creating a memorable experience for visitors. The Instant House installed here is used not only for guest accommodation but also as a showroom for camping business operators to experience the product in a real-life setting.
While general tents have a lifespan of only 1–2 years, the Instant House can be used for up to 10 years. Designed to Japanese standards, it withstands strong winds, heavy rain, typhoons, and even earthquakes. In other words, it offers both “long-term reliability” and “high investment value.” With a whimsical, almost fantasy-like exterior, the Instant House is highly photogenic and perfect for social media. But the appeal is more than just looks. ・High-Quality Polyester Sheet Exterior ・Durable Structure Instant Houses come in three sizes: S, M, and L. All products include a 3-year warranty and free maintenance. Installation, transportation, and labor costs are all included, so there are no unexpected additional expenses after purchase. The L-size Instant House offers comfort comparable to an actual home. It can fit two 5-foot beds, accommodating 4–5 people, and can be expanded with an attached bathroom. It truly creates a camping environment where guests can “relax as if at home.”

Instant House: Unique Design and Superior Functionality
【Key Features of the Instant House】
・Quick Installation
With expert staff, installation can be completed in just one day.
・Eco-Friendly and Safe PU Foam Insulation
Developed in Japan, PU foam is used as thermal insulation, maintaining an indoor–outdoor temperature difference of about 5–10°C. This significantly reduces electricity costs.

The exterior walls use high-quality polyester sheets coated with fluororesin. This is the same grade used for warehouse tents, providing excellent durability. The material prevents condensation, mold, and moisture, and is flame-retardant, ensuring safe long-term use.

Since no steel is used, there is no risk of rust, allowing installation even in coastal areas.
A New Camping Experience: “Relax Like at Home”
In Thailand, the camping trend has been growing rapidly in recent years, especially in easily accessible areas near cities. Demand is expanding particularly in Khao Yai (Nakhon Ratchasima Province), as well as in coastal provinces such as Chonburi and Rayong.
Meanwhile in Japan, more than 147 Instant Houses have been installed across over 50 sites, from Hokkaido in the north to Okinawa in the south. They are used not only as resort accommodation but also as spaces for sports and relaxation.
Tomas Engineering’s Instant House offers a new style of accommodation that lets people enjoy nature in comfort. With long-lasting durability, eco-friendly insulation, and an eye-catching design, it continues to attract the attention of both camping business operators and end users alike.
