Started working for my dad's water treatment company in my teens, installing and repairing pumps and water treatment systems. Later worked on automated monitoring and control systems for small water treatment systems, including PLC programming, panel design, systems integration, and designing and building our own SCADA software package. Currently employed as a senior software architect at a print software company.

Renovations around my houses have included installing complete bathrooms (both reno and adding new), complete basement gut and reno, and all types of electrical, plumbing, and ethernet/video/audio cabling. Also have a particular interest in home automation -- my current house has several rooms controlled using Insteon gear.

comment Are galvanised steel pipes suitable for supplying hot water?
I'm having a hard time finding good citations, but: it is thought that hot water affects the galvanized coating and increases the rate of corrosion and build-up inside the pipe. Galvanized pipe is apparently no longer allowed by code in Canada for (treated?) potable water (inside, anyway). Depending on the chemical composition of your water (pH, dissolved minerals) it may react with the pipe, causing other contaminants (a concern mostly if you are not on city water). Though you don't typically drink shower water, it does get absorbed into your skin and dispersed into the air (and your lungs).

comment Surveillance System and Home Automation in Europe
In addition, many stand-alone security systems have interfaces to insteon/UPB/etc just to signal armed/disarmed/alarmed, so if that's all you need it may give you some more options in choosing a security system. You need to define what it is you'd like the automation to do, and then you can figure out what products to use and how much it will cost to achieve those features.

Are you tied to X10 specifically? X10 is widely regarded to have many problems (eg, see diy.stackexchange.com/questions/333/…). It is very susceptible to noise and interference, including false signals that trigger lights on/off (or with a security system: false alarms), and missing legitimate signals due to interference. There are many newer systems that work much better.

comment How can I tell if these pipes are gas lines or water lines?
What material are the pipes? A picture would be helpful for sure. Can you see them and where they go from underneath in the basement/crawlspace?

comment What should I consider regarding LAN wiring before building a house?
@Steven ENT (non-metallic) is probably more practical/common for home and DIY use. I've also used utility pipe as conduit many times (it's black poly, rated at 75psi), and comes in rolls so you can do one continuous piece. Compared to ENT it's slightly easier to kink while installing, but otherwise works fine as conduit.

comment How can I add a closet to an existing room?
If you show some more of the surrounding floor plan, we may be able to suggest some other alternatives as well. For example, it is sometimes possible to split an existing closet in an adjoining room into to. You say the one door can be removed -- where does it go? Can the inside of that room be turned into a closet?
