Build Your Own Home

Posted By Rafter Tales Staff On January 12, 2008 @ 5:04 pm In Home Building | No Comments

When I first decided to build my own house, I was so excited.

I figured six months, maybe eight tops, and I would be in my new home sipping coffee!

Well, eighteen months later, I moved into my new home. But it was worth every bit of the headache, sore muscles and time spent.

Nothing could be more fulfilling than living in a home you helped build with you own hands!

Ideally, every day is either sunny or partly cloudy with no chance of rain, and seventy degrees. But that never happens.

Building your own home may seem like an impossible task, but if you have home improvement experience, you can learn the steps needed to be your own general contractor!

Suppliers may ship your entire order when you order it and
subcontractors run into delays on other job sites. So, you have to be
prepared to handle setbacks and manage chaos.

There’s pretty much a set order of how things are done. The primary
reason is due to codes and permits that apply across the country.

Another reason is cost; proven methods used to build homes help to
produce reliable housing quickly, and at a relatively low cost. While I
can’t prevent your own panic attacks about never being finished with
your home, I can give some ideas and a guideline of what to expect and
when.

Site Preparation and Foundation

The first crew on the site does grading and site preparation. Often,
site prep and the foundation will be done by the same contractor.

The most common foundations for building a home include
slab-on-grade, basements and perimeter foundations with crawl spaces.
This is a major decision to make when working with your architect and
will be based on your home’s design, local codes and conventions, and
potentially by your home’s building site.

Framing and Roof Trusses

The framing crew will be next up. They start with the floor, unless you are using a slab foundation.

The floor starts with a sill-plate made of pressure-treated lumber
in direct contact with the bricks of the crawl space wall. Once the
floor framing is complete, it is covered with 1/2-inch or 5/8-inch
plywood or OSB (oriented strand board).

Next, the framing crew next starts framing the walls, which are assembled on the floor and then raised into place.

Once the walls are framed and raised into place, your home begins to take shape.

Sheathing is typically put on using either OSB or plywood, giving
the walls exceptional rigidity. This negates the need for diagonal
reinforcement used in older homes built prior to the availability of
these products. Plywood or OSB sheathing is much stronger.

Pre-fabricated trusses are a good way to go for roof framing. These
Triangular wood-framed structures support your roof. Another
alternative is to build a frame for your roof using 2×8 and 2×10
boards, which is substantially more time consuming.

Trusses are popular and have several main benefits:

  • Trusses provide superior strength
  • They are also cheaper, since they can be manufactured using short lengths of 2×4 lumber
  • Custom ordering trusses allows unique architectural features like cathedral ceilings without breaking your budget
  • Trusses are good for long spans, since they transfer all of the
    weight to exterior walls. This allows greater flexibility for placement
    of [1] interior walls, since they are not load-bearing
  • Trusses are installed very quickly, helping accelerate your project
  • As a homeowner, the only real disadvantage is that your home has attic space

Doors and Windows

After the roof trusses come doors and windows, which should be
ordered and scheduled to arrive as a single shipment, so that they can
all be installed at one time and prior to roofing. This is because
adding the weight of roofing materials will cause settling, so you want
to install door and window frames first.

Roofing and Siding

Roofing comes next, with tar paper being laid down and your roofing
materials. This process varies somewhat, depending on whether you have
chosen shakes, composite shingles, tile roofing, metal roofing, etc.

Then comes siding; one good choice is to use vinyl siding, which is
less expensive than many alternatives. Cedar is also a common natural
material used for siding. Stucco is also popular, especially in the
Southwest, where its insulating qualities make it extremely desirable.

Most of the rough plumbing and electrical is done after framing, while the walls are open.

Next comes rough plumbing, when your plumbing contractor runs water
supply and sewer lines. Bathtubs and shower pans are typically
installed during rough plumbing since one-piece shower-and-tub units
are so large and not easily maneuvered into place later.

Tubs are also notorious for being delivered slightly different than
the size ordered, which makes installation very hard later in
construction. A full tub is also heavy, so by installing and filling
it, you help the frame settle more quickly, preventing wall and tile
cracking once the tub is put into use.

Rough plumbing will normally include water supply lines for all fixtures and installation of sewer lines and vents.

Electrical rough in typically follows rough plumbing. Your
electrical contractor will also install hardware such as electrical
panels, lighting brackets, electrical outlets and junction boxes at
this stage, leaving only the “finish” pieces such as cover plates,
lighting fixtures and switches until the finishing phase.

Insulation and Drywall

Next is insulation, which can include many types and installation
methods. One typical type of insulation for walls is fiberglass rolls
that are cut to length and installed between wall studs. You may also
use spray-in cellulose insulation. These options should be determined
ahead of time during planning so that the correct sequence can be
determined.

From the exterior, your house now appears nearly complete! However,
inside things are still pretty rough. Next up is drywall and then its
time to begin finishing.

Drywall, also called sheetrock, is the most common type of interior
wall product used in most homes. Although drywall sheets are only
1/2-inch thick, because they are made from gypsum, backed with paper,
they are quite heavy and solid.

You can do drywall yourself if you have a strong back and a hoist!
However, it is probably best to hire a professional crew since they can
easily do the entire home in a day or two, depending on square footage
and the complexity of your interior.

Congratulations! You have now completed rough construction and all that remains is the finishing phase.

Finishing Phase Steps:

  • Underlayment — Plywood sub-flooring is laid during
    initial framing and covered with tar paper or a vapor barrier
    (4-mil-thick plastic) and 5/8-inch particle board for most areas, or
    concrete wonderboard in areas like bathrooms where tile will be
    installed. Complete any remaining underlayment or subfloor work
    required before finish work begins.
  • HVAC — Your HVAC contractor will return to install
    heating and air conditioning equipment, vents and ductwork. In a home
    built on a slab foundation or in a two-story home, some of the ductwork
    needs to be installed between floors and inside walls. In a
    single-story home with a basement or crawl space, HVAC equipment and
    ductwork can be installed late in the project since it will be under
    the home.
  • Finish electrical — The electrician will return and install all light fixtures, wall outlets, switches and cover plates.
  • [3] Kitchen and bathroom cabinets and counter tops
    — The cabinet installers must be scheduled to install all cabinets in
    the kitchen and bathrooms. These will be aligned in place on walls and
    attached to wall studs with screws and then the counter tops screwed on
    top.
  • Finish plumbing — After cabinet installation,
    schedule your plumbing contractor to do finish work, installing
    remaining fixtures like sinks, toilets and faucets, as well as your
    water heater if it wasn’t part of the rough plumbing phase.
  • Paint, trim, flooring and other finishing details always take more time than expected.
    Paint, trim, flooring and other finishing details always take more time than expected.
  • Water and sewer hookups — Your home will need to
    be connected to municipal water and sewer lines. Usually this is done
    by your municipality or else your plumbing contractor. If public water
    and sewage lines are not available, you will need a private well and
    septic system. In this case you need to hire a well-drilling
    subcontractor and a septic-tank subcontractor.
  • Wall trim — Once the cabinets are in, the interior doors are installed and the molding around the doors, windows and baseboards goes in.
  • Paint — Once the molding is on, it is time to paint and wallpaper the interior of the house.
  • Carpeting, flooring and tile — Once the paint is
    done, carpet, wood flooring and tile can be installed. With some
    flooring products, you will want to install baseboard trim after rather
    than before the flooring.
  • The final punch list — At this point, the builder
    (in this case you!) inspects the house, noting any problems. All
    problems are tabulated on a punch list. The various contractors return
    to fix all of the problems. Be warned; this is typically an iterative
    process. Also, final inspection by your municipality’s building
    inspection department needs to be scheduled. Once the punch list is
    done, it’s time to move in!
