In short, modular building prices can vary dramatically. Firstly, you need to consider the size of the building. 2 Bay modular buildings are often the most cost effective, ranging from £5,000 - £25,000. The more bays that are added to the design, the more expensive the building becomes. A standard 6 bay double classroom will set you back around atleast £50,000. This is because of installations, foundations and delivery. These three key features are all important elements in modular building projects. For installations, this will normally require trained staff to bolt the building together and ensure the building is stable and structurally sound. Delivery is entirely dependent on the distance the building will travel. This is why buying a refurbished building can help reduce costs dramatically. Foundations can be a costly part of the process, as delivering a building on grass is considerable more than tarmac. See our full range of modular buildings here. Modular building prices are also depedent on the interior features of the buildings, we can offer toilets, partitions, showers, ramps and stairs.
