    I apologize for not knowing the technical name for the house type. The
    house exterior walls are formed using Styrofoam and pouring concrete between
    the Styrofoam walls.

    Here's my problem. I haven't installed a system in a house like this, and
    I'm not sure how to run the wires to the windows and the doors. The windows
    sit about 6 inches away from the interior wall. To run the wire that deep,
    would mean drilling through the poured concrete. What I'm trying to avoid
    is showing to much wire. I want the job to look as clean as possible.

    The other problem I'm running into is with the doors. The doors aren't
    installed yet, so how do I know where to run the wire to. I'm installing
    recessed contacts at the doors. The doors are framed out, but there isn't
    any markings to help determine where the door will be in the 8 inches of
    space.

    I hope this made sense.

    Michael,

    I was asked last year to get involved with a group of builders that were
    going to build this type of house locally. They wanted to get within the
    group electricians, plumbers, telco, carpenters, automations, security, all
    the trades to pull together resources and talents. This was so that if
    someone was convinced that this type of building construction they would
    have to use one of the group for services. I was give the sales pitch on
    the construction of building walls of concrete for both exterior and
    interior walls from the basement to the attic which included floors.

    I made my decision early not to get involved and then asked how they planned
    to get low voltage wiring from the basement to the attic not to mention to
    windows and doors for existing and future wiring projects. The statement
    was made like this. "Wow, we hadn't thought of that, thanks we will have to
    work on that part." Duhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

    IMHO and you want to install a hard wired system, bid it very high and work
    your ass off. Be prepared to make repairs to walls and try to be very
    accurate with your hole drilling. Wireless my work but I would be concerned
    with the concrete walls and floors blocking the signal.

    Good luck.

    There still must be chases for the existing wiring, plumbing etc in there.
    ITI and Ademco have nifty concealed wireless contacts for doors and windows.

    So it seems there no magic fix for this situation. Could it be possible
    that I just won't be able to get the hole to the window close enough to keep
    the wire run show worthy short?

    When I started this business my game plan was to do home networking. Then
    someone explained to me the structured wiring system, so I decided I should
    do that as well. Then someone said, well you should probably install home
    automation and security, so I've begun the process of learning that. My
    game plan/business plan was to install the structured wiring and home
    networking in low level houses to build up some proper experience. I was
    thinking some nice 4 telephone, 4 TV, home network system, leave the
    security to a security company. Well that hasn't worked out. My first
    house is a 5000 square foot, poured concrete monstrosity, with 19 telephone,
    cable, and network outlets plus security, and central vacuum. My Uncle, who
    was kind enough to offer the work to me, assures me I'll figure out. My
    second house, another poured concrete home. Talk about your business trial
    by fire.

    I appreciate all the posts from this group, and your help with my questions.

    Michael,
    I just got thru pre-wiring a (Ice Block House) it is constructed as you
    have described, Basically I had to triple the amount of labor for the job.

    All my wiring between floors and down walls was inserted in a groove that
    I had to create with a 400 degree wedge shaped Iron. After the wire was
    placed in the groove the tool was then flipped over and re melted the foam
    in the opposite direction creating a conduit of sorts that hold the wires in
    the foam. As for getting the wiring to the doors and windows, there was a
    layer of foam all the way around the openings that the builder attached
    his framework to. Several trips had to be made to the job to go thru the
    steps of putting everything where it belongs.

    This type of house gets very expensive for homeowners, but if they
    can afford it, provides a insulation value almost unbeatable.

    Good luck, hope this tidbit helps some.

    Go wireless...

    We used the Ademco recessed wireless contacts on a home that was solid
    concrete construction (early "tilt-up") with no problems. In this instance
    we used two receivers. One on the main level and a second on the third
    floor. This covered the basement, first, second and third floors. On
    interior walls we went hard wired.
