How Much Does It Cost to Build a Pre-Fab Garage or Barn?

Updated February 21, 2017

A prefabricated garage or barn unit comes in a single kit that allows an owner to set up the structure, usually with very little outside help. The materials are all included, and the costs are kept low by avoiding contractor work and simplifying the construction process whenever possible. While a prefabricated structure may not have the durability or features of a full model with a foundation and insulation, it can still be used for a variety of purposes.

Metal Buildings

Wooden barns must typically be built by hand, and few reliable versions are available in kits that owners can buy and build with prefabricated parts. Instead, metal buildings are a more common barn solution where prefabrication is key. A kit for a metal building started at £3,250 in 2011 and increased depending on the size of the building, what materials it used and how complex it was. Average structures tended to cost around £6,500 while the larger versions including windows and insulation cost closer to £9,750, which does not consider the cost of any necessary foundation work.

Garage Kits

Garage kits tend to be designed for smaller structures, which can help to lower the cost for the most basic types of garages. A typically prefabricated version cost £1,950 to £2,600 in 2011, which included only a simple design for a single-car garage with no windows. Costs can rise to £9,100 or more for kits designed for two-car garages with greater numbers of features.

Storage Shed

If owners are looking for a simple storage shed option that can be used for a variety of purposes, costs are often decreased. Manufacturers can create plastic options and use other alternative materials that have lower costs. A mail-order kit in 2011 cost between £1,300 and £3,900 for an 8 x 10 foot storage shed. Smaller versions may be available for only several hundred dollars, making this an ideal solution if homeowners are only looking for simple storage capabilities.

Pole Options

Pole barns do not need any type of foundation, can have open sides and can often be moved from location to location. While they are not technically prefabricated barns, they are sold in kits that cost between £3,250 and £19,500. This wide range shows the different options available regarding size and extra features like windows, sliding doors and storage lofts.
