What is a modular building?

Starting with the basics, we thought we should explain what a modular building actually is. A modular building is a pre-fabricated structure that is built off-site in a factory. The units are later transported to the construction site where they are installed. These buildings are constructed from the ground up, meaning they’re structurally sound from the very start. This means that these structures are often more energy efficient and sustainable, in comparison to traditional buildings.

Why are modular buildings so popular?

We have seen a huge growth in the use of modular cabins for a variety of projects over the last few years and it’s easy to see why they are so popular. They are an affordable and efficient alternative to traditional buildings that can be constructed in a fraction of the time. They are utilised for a range of different uses across multiple sectors.

How long do modular buildings last?

Modular buildings can last virtually as long as traditional buildings. However, how long they last largely depends on the materials used in their construction and, how well they are maintained. They are designed with a long-life span in mind in such a way that they can withstand extreme weather conditions and remain structurally sound for many years. Here at TF Jackson’s all of our buildings, are weatherproof, insulated and highly durable and if maintained properly they can last for 30 or more years, sometimes longer.
