If I were to run a fibre optic HDMI cable from My receiver To my imaginary projector, would you think 10m would do it or 15m to be safe?

Ceiling height is 2.7m, length of room 4.7m.

Will 1k cover it? He can include more in contact price, and credit anything that isn't used. But if I don't include it and turns out to cost more than agreed contract, mortgage won't cover it, and will have to pay for it ourselves

sensor lights (I assume a tread light down low) will be about $75+GST ea for LED, plus cable, labour. 3 in hallway is likely to run $4-500 incl labour and a sensor). 2 in the lounge, $3-400.

USB sockets are expensive, 3x the cost of a standard double socket (again, $60-$70 for a double socket with twin USB), no real difference in fitting costs.

Long HDMI, about $150-200 for a 18gbps one, but thats HDMI2.0, not 2.1 I don't think they do 2.1 that length yet (could be wrong).

Cat6, allow about 20m per termination, so a 300m roll will be good for about 15 points. With connectors, plates, network cabinet, patch panel, I would think that even 1 roll worth of cat6 will set you back up to $1k in itself (incl labour etc)

At cost, my house build electrical is going to hit around $24k, this would be about $33k +/-at normal margins

Admittedly, I have over specced a lot of things -

x2 8kw ducted heat pumps (1 for living areas, 1 for bedrooms).

power sockets up the wazoo

network connections in each room, + about 6 in home theatre, 3 in living area av area

alarm with remotes, pet sensors & IP module

sensor lights in hallway, ensuite with led strip off sensor

undertile heating

It has all added up very quickly but having lived in a house where the electrical has been well and truely undercooked (1 light in the master bedroom????), with electrical, less is not more and its never cheaper to put in electrical connections than at the building / planning stage.

If you can keep within about 10% of your budget, your doing well.

I ran OM4 fibre cables from central media and switch rack locations to office, and multiple TV locations so in future I can use a fibre to HDMI converter and have capacity up to 100gbps. OM4 cables from fs.com are cheap and 15m will do the job. As mentioned above, install power points as many as you can in all rooms. We have cabled for 67 double power points in our build.

Do whatever you want to do man.

For my own imaginary projector, the sparkie is recommending just leaving a loop in the roof space to add power later and running draw wires and decent size holes in the framing for pulling cables later. He has twice recommended against conduit, I think the rationale being that once you get a couple of cables in the conduit they are more prone to getting stuck.

In my case the cabling will all be straight down the wall, so no bends or corners to deal with; and with (hopefully) enough roof space to be able to physically get directly above the wall.

His advice may well be quite different if we were dealing with bends or corners.

EDIT: I'll ask here while we're talking about cabling. What's the best stuff to use for draw wires?

Left over cat 5 or 6 for draw wires or appliance wire even seen baling twine used.

I used leftover CAT6 cable I had lying around for a while for all my draw wires through the conduits.

Thanks for the replies, sorry I didnt reply, things came to a grinding halt with the build (although Ive kept looking at stuff)

Things seem to be slowly going forward again, although have quite a big concern. The valuation has come through and he has questioned the position of the house for sunlight, he wondered if it would be better to flip it. His words:

'The house is not considered to be ideally positioned on the site with its most northerly most aspect for the sunlight hours orientated to the service rooms. The family room is likely to receive some afternoon sunlight'

I thought they way it is would be best for sunlight in afternoon / evening for kitchen / deck etc.

Can anyone confirm this? I have no idea where the sun will be at different times etc.

Thanks

That's a good point, you definitely want to orient it for the sun. It starts in the East and moves across to the West, lower in winter, higher in summer. Check out https://solarview.niwa.co.nz/

Good all day sun makes such a difference to the livability and comfort of a house. Not the mention the reduced heating cost.

Keep in mind that most days don't have full sun from 8am to 8pm. It might be sunny from 10am to 1pm, then cloudy for the rest. So in your current orientation you'd have a nice warm master bedroom and dark and cold lounge and dining area. Our place here is long and East to West, so we get all day sun in almost all the rooms. It makes for very comfortable living in the South.

I would rotate your whole house about 90 degrees clockwise if you can.

Thanks for the reply and info. Unfortunately it cant be rotated 90, just flipped / mirror image.

I've just found this which seems really good. http://sun-direction.com/city/43297,christchurch/

From what I can tell, I will get the afternoon sun on the deck / garden and kitchen which would be preferable wouldnt it?

thanks

how would you do that when its on a rectangle section? can only mirror.

personally i would leave it, i would rather have afternoon sun in the living rooms, and morning sun in the bedrooms.

Exactly. Morning sun helps you wake up properly, and you'll get nice afternoon evening sun into your living area/deck (assuming you're not going to have a 2-storey house on your west boundary blocking the sun!)

Ideally you need living areas (lounge, dining, kitchen etc) facing North, then these areas get sun all year round and your house will just feel warmer. We built a place with North facing living areas and it works, really nice getting home in the winter and the place is warm, often we don't even need to turn a heater on all evening. But then we thermally broke windows and filled with Argon and insulated the slab plus extra insulation in walls and ceiling - I'm sure someone has told you 'built to code' is the worst house you can legally get away with building. I'm not a fan of bedrooms facing West as during the summer those rooms will get hot and no one likes a hot bedroom? To be honest I would prefer an East facing bedroom to West facing as you can wake up with morning sun. Not sure how you will do this with your plan, honestly it doesn't work for sun and this is a big thing, you will feel happier in a warm sunny living area - it's hard to put a price on this.

Maybe see if you can find a better plan with the rooms in the right place, if you are spending all that money it might as well work for you. Good luck.

I agree with this. I feel your design has so many compromises it might be worth starting again. Eg think about where you want the living areas in relation to the sun. They are the rooms used the most. Then try and place your other rooms around that keeping within the restrictions of the section.

I don't agree you need morning sun in the bedrooms. For me I'm well awake before I get up and open curtains, so wouldn't get any benefits of morning sun in the bedroom. For me kitchen would be a better place for morning sun. Then living areas from late morning through to afternoon.

I wonder if you could put kitchen in the top right NNE corner. Living areas left of that, opening out into the back yard. Bedrooms and garage etc south of those. Try and avoid evening sun in the bedrooms.

Houses should be designed for the site and conditions and sun orientation. Try and avoid taking an off the shelf plan then fitting it to your bit of land. Not sure what went behind the scenes to get to where you are now.

Bit late to the party here, but i'd put more value in generous sized rooms compared to an extra one (which is really small anyway). North facing side of my place has lounge / dining / kitchen / living. The original plan for your kitchen is basically what I have, though scaled up with a larger area between kitchen and dining. I think I prefer the original plan without the drawing on it. The one with drawing basically removes the living area. So you may as well move the family room up a bit and perhaps expand it larger. The edited living area doesn't have space for anything so is a bit pointless IMO.
