How can I find out what supplies and how much of them it will take for a 240 sq ft room addition?

Question

room addition size wanted 240 sq ft (24'x10')
no windows
using back of brick house for one wall
on slab

Answer 1

Draw up what you want and be sure to include all dimensions. Take drawing to a builder or a lumber yard. Thay can figure the materials.

Answer 2

How long is the brick wall is the first question I'd need answered. Then it will be possible to figure the materials for the remaining walls. I'm going to assume that the brick wall is 24 ft. long. Then I need to ask about the climate you're building in as this will determine the suggested thickness of the wall and whether insulation should be included in the materials. Also, how many electrical outlets are going to be installed? Is there a slab under the area where the room is to be built? Is there a foundation? Do you want a wooden floor? Is the entrance to be made through the brick wall or is the addition going to have an outside and separate entrance? Do you want wood frame construction, concrete block, brick, or poured concrete? Are you beginning to get the picture?

You need to define what it is your going to build and what it's to be built of. The matter of the foundation or pad of the utmost importance. All of these questions need to be answered before anyone can give you any reasonable estimate of the materials you will need.

Think about it and come back with a more detailed description and you will get all the help you need.

Good luck. I'm looking forward to helping, hopefully.

Answer 3

If you are doing this project yourself, you should have the knowledge to etimate the project. For example, assuming you come out 10' from house and 24' wide and using 2x4 walls, if you frame it, the walls would require:
44' feet of sill gasket.
44' linear feet of pressure treated 2x4 for sole plates.
88 linear feet of 2x4 for top plates
33 studs plus a few for corners and jack studs, say 42 studs.
4 sheets of 1/2" osb
7 sheets of 1/2" foam board insulation, more if over 8' walls
Opps, forgot headers if you have a door, size depends on door.

That just covers framing walls. It took a couple of minutes. But the point is that if you have the knowledge to build it, you have the knowledge to put together a material list. Take that list and go shopping. I'd look at local lumber yards first. But on framing lumber Lowe's or Home Depot will be competive, they just don't have the service that your local lumber will have.

So you break down the project into smaller parts, foundation, walls, roof framing, roofing, door(s), exterior finishes (brick siding stucco, etc) insulation, interior finishes (drywall, paneling, trim, etc.) mechanicals (hvac, electrical, I assume no plumbing) lighting, paint. And you add it all up, and go shopping.

Then you do the same for labor. Break it down, and make some calls. Even some things, you may find it is better to hire someone, because the amount of time you spend on it you might just want to hire some. For example, if you side it, at 4.4 squares, you may find someone willing to do a little project for a couple hundred bucks. It is a weekend project for a novice. Not trying to be rude, but if you are novice (God knows I am at certain projects) it may be worth the money to have the professional do it, and you work on other things.

If you can't estimate it yourself, then you probably should get a contractor to build it He will give you a set price and you won't have to worry about materials. If there is a certain thing you want to do, he will give you an allowance on it and you can save a few bucks.

Good luck.

BTW, you do know that if the slab is just a patio, you need to add footers. Most patio slabs are just 4-6" and aren't suitable for building a structure.

Answer 4

you may desire a 2 ton or 24,000 btu's to good cool a 1100 sq. foot domicile. That length isn't attainable in a window a/c. in case you are able to't use a mandatory air device then evaluate a mini-split device. If that isn't a threat attempt employing 3 or so window contraptions sized for the rooms they are going to be in. additionally they must have separate circuits so your no longer blowing circuit breakers all of the time. Your electric powered expenses for working the window contraptions would be severe and the contraptions will supply some noise.

Answer 5

I know lowes.com has apage on this maybe even home depot, but anyway go to lowes.com on the home page click on how to projects or job calculator,it will ask you what you plan on putting in the room,like what type of floor,what tpye of walls,and ceiling type,then it will give you an estimate of the materials needed and the cost of them.they also have a help desk right at lowes where you can get this info also.

Answer 6

There are some nice 3d architect programs which will help you design your addition, and then figure the materials as well. The one I used, though it was some time back had that name "3d Architect"

Answer 7

I will sad take some free estimate first so yo know whats going to take. And them you can make your maind
