Howdy adamyurdock1,

 

The costs associated with adding a new room onto your home can be broken down into labor and materials.  Labor costs will be higher if you hire a contractor, or you may decide to have friends help and do it yourself. Whatever the case may be, understanding your costs prior to beginning a room addition can help to stay within budget.

 

Room additions can cost up to 50 percent higher, between $80 and $150 per square foot before considering wiring and plumbing, than that same room had been constructed with the rest of the house. The services of a professional contractor/architect, who would draw up the plans for the room, may be between 5 percent and 15 percent of the room’s construction costs.

 

Figure out what fixtures you plan to add to the room. Plumbing work and the installation of a bath and sink will increase the cost of a bathroom over a similarly sized family room that which may just have furniture.  Also consider the plumbing or wiring you need to purchase for running water or electrical appliances.

 

Here is a basic material checklist for a 12x12 foot room;

 

Purchase five sheets of 8-foot by 4-foot plywood for the subfloor. Drywall or paneling is typically used on the walls and ceiling, so plywood isn't needed for those. The exterior walls require 12 sheets of plywood. Eight-foot long 2-inch-by4-inch lumber is used for wall studs. A 12-foot-by-12-foot room requires 28. Buy a few in addition in case you discover flaws in one of the lengths of lumber.


A total of 17, 4-foot-by-8-foot sheets of drywall are needed to cover a 12-foot-by-12-foot room without doors or windows. The number of doors and windows the room has lowers the amount of drywall needed. The walls require 12 sheets. The remaining five are used on the ceiling. About 650 drywall screws are necessary for wall panels installed vertically on 16-inch center. The ceiling panels take about 765 screws.

Finishes include crown molding, paint or wallpaper, switch plates and outlet covers. Plan 3 gallons of primer and 2 gallons of paint for the walls. Plan 1 gallon of ceiling paint. Buy at least two paint rollers.and an extension pole for painting the ceiling and various sized brushes for hard to reach areas and edging. Eight rolls of wallpaper suffice if each roll covers 56.4-square feet. A kit containing a roller to work out air bubbles between the paper and the wall and a long tub for soaking the paper comes in handy. Plan on one switch plate for each wall switch and one outlet cover for each outlet.

A little more than 16 yards of 12-foot-wide carpet covers a 12-foot-by-12-foot room. Sixty-three 18-inch-by-18-inch ceramic tiles will cover the floor. That number more than doubles to 141 for 12-inch-by-12-inch tiles. A little more than 150 square feet of hardwood or laminate flooring is necessary, allowing for a five percent waste factor. Baseboard molding comes in 12-foot lengths, so four pieces is appropriate for a room with no windows or doors. Adjust your calculations for how much molding you need based on the number of doors and windows in the room. Remember to add 7 to 10 percent to your calculations for waste.

 

 

Make sure to address other costs associated with the addition of the new room when calculating its overall cost. You’ll generally have to pay a disposal service for cleanup and removal of old or excess materials. Understand that an addition to your home will very likely also cause your home insurance, utility bills and property taxes to increase, as well.

 

Be aware that building permit fees that must be paid to your municipal government may add to the overall cost of adding a room to your home.

 

Happy Building,
