40 X 40 Metal Building – A 30’ x 50’ and a 40’ x 40’ metal building differ vary little in actual square footage, but the best end uses for each may be radically different.
If your property allows space for the wider 40’x 40’ metal building, you may find the square-shaped building has real advantages over the rectangular 30’ x 50’.
For example, the wider 40’ structure allows for a roomy 3-car garage with additional storage in the back. It could even be used as a six-car garage, since the 40’ length is adequate for parking vehicles two deep at three garage doors.
With increased height, a 40’ x 40’ building might house an RV and two cars across the endwall. You could even have three car-sized overhead doors across the endwall, and still have room to park a motor home across the back of the building in from of the cars with access from an RV-sized door in the sidewall.
The 40×40 metal building is delivered as a kit and installed on your level land. Due to the weight of the building you will need to rent a telescopic lift that can go 2′ taller than the leg height of the carport or garage. The lift will need to be able to lift 5000 lbs. As long as the lift is on site the day of installation, set up is free and usually takes about 1 day for the 40′ wide carports to be installed and about 2 days for the fully enclosed 40×40 metal garages to be assembled.
The exact outside to outside base dimension is 40×40; however, the size is listed as 40x41to include a 6″ front and 6″ back end overhang. So, if you’re going to put down a cement slab for your 40 x 40 steel building, you will want to make sure the exact size of the concrete pad is 40′ wide by 40′ long. Of course you may want to have an apron in the front. If you decide to put a gravel pad down for your 40 x 40 metal building, then a 42×42 size pad will work great giving you 1′ extra gravel on both sides and ends.
What’s left to consider? If you are not building on an existing foundation, you will need to pour or build that – increasing your overall cost between $4 and $8 more per square foot ($9,600 to $19,200). Plan your foundation with a flooring plan built in (a floating concrete pad is a good example). You will also need to account for labor costs to build the structure. Installing it using the manufacturer’s directions may be simple, but be sure to have plenty of help for a building of this size.
If you choose a Quonset hut style building, your materials, accessories and delivery cost will decrease. A 2,400 square foot Quonset hut will run you about $7.50 per square foot ($18,000) for materials, $1,440 for delivery and an additional 20% ($3,600) for accessories. The on-site, materials cost of a Quonset steel building is $23,040 – a savings of over $4,600 over the straight wall system.
As both styles of metal building systems are intended for ‘Self-Build Construction’, you can save up to 68% on this type of building compared to a ‘General Contractor’ erected wooden building
You will also save on maintenance costs as you will not be replacing rotten wooden boards and roof tiles in 2-3 years
Finally, you will save on paint and finishes as a metal building arrives on-site primed and painted, this also goes for the roof!
