Orange = sockets
Purple = lights
Light blue = switches
Dark green = cat
Light green = aerial
Pink = tv

Am I right???

That is a lot of cats. I am allergic to them as well so could not visit. Have you considered dogs?

I'd love to know how they got that off the back of there and into the house?

Simplistically, he drove the van onto the drive and raised the tipper about 6 inches so the top of the beam was higher than the flat garage roof. I'm not exactly sure how they got it from there onto the flat garage roof, but from there is was moved on rollers across the roof, through a hole in the wall and straight into the kitchen at the correct hight.

My neighbour took a few pictures of the operation for me (since I was at work). I'll hopefully pick them up tonight and it might answer a few questions!

I knew the lamp circuits wouldn't be obvious to most people. We saw them in a house many years ago and it seems such a sensible idea. A light switch by the door that switches all the lamps on and off in the room.

Lamp circuits are a great idea... We had them in our apartment in France, where they appear to be quite common.. We ended up replacing the simple switches with control panels that set up zones and mood lighting .

Since you've got ceilings and walls to re-plaster.. I'd drop a few more cat6 around the house , I floodwired my ceiling voids and left them unconnected ( but with photos showing where they were). Then when I needed a few extras for webcams and sonos it just a channeling down the wall to where I needed them...

Why does everyone choose Cat5 instead of 6 or even 7?
Just wondering, since the standard for us locally is 7.

The same reason I hoover the carpet with a Miele.

Everything will be cat6 throughout.

Day 19


New roof structured for existing extension so it can take 2 large Velux windows. Cables run for lighting in the ceiling.

Nice one.

Wish you all the best, you took a risk and it seems like you are going to do very well.

Can't wait to see the end product.

Bookmarked!

I really enjoy the build threads on here. smile

There are a lot of lights in that kitchen, just lighting bits of floor....just saying. I really do like the kitchen design though.
Agreed. Love the kitchen design but too many down lights

The lighting is changing. You might not like this, but there are going to be even more lights!

The lighting diagram above was a theoretical attempt before we knew whether the beam could be completely hidden within the ceiling and before we had decided on Velux windows. In the end, the beam had to be 12" high and therefore will project a few inches into the room. We are also having two huge Velux windows to let as much light in as possible because the room in north facing.

What this means is that we are losing the 3 feature pendants over the island because the ceiling above the island has 3 different levels.

The 2 parts of the roof (original house and existing extension) have joists in different positions and recessing lights in locations that are suitable for both was very tricky. The only way we could make it work was have 6 across the room. The joists are almost made-to-measure and 6 will be perfectly spaced. We also need to position 2 of the lines of lights around the Velux windows.



We are wiring them in multiple circuits with a dimmer on each circuit so we can control how much light each zone gets.

I get that you have to take joists into account but waaay too many lights. What you have there is shop lighting. Half of them are merely lighting areas of floor and are not required. You should place them around the working areas only for a good affect.

But then, it's your house so if that's what you want who am I to argue!

I'm far from an expert on this and have struggled to find guides that actually tell you how many lights to install. One guide I've found is here:
http://www.switch2leds.co.uk/knowledge-base/beam-a...

Basically they distil it to this formula:
Number of fixtures = (Lux level * room area) / lumens per LED Lamp

They advise a Lux level of 250 for kitchens. Our kitchen is 34m². If I install 400 lumen bulbs then I get:

250 x 34 / 400 = 21.25

24 doesn't seem excessive. What am I missing?

Don't know about number of lights ... ( 18 in my kitchen..excluding plinth lights though )

However ...be careful with the positioning above the kitchen counters ... Looking at your diagram and the earlier 3d from the kitchen company, I think you might be casting shadows over the worktop . I got it wrong first time round :-(

Maybe move them towards the middle of the counters so less chance of shadow

This site is a load of guff but anyway, they are suggesting an OVERALL lighting level. Why would you need 250 lux over the floor? Are you going to sit cross-legged in the middle of the kitchen with your newspaper? If you are then go with that!

You only need anything like that level over worktops and kitchen island - the action areas. Everywhere else you can decrease. LIghting should be used where it's needed then you get a much nicer effect overall. Kitchen is the hub of the house and should be nicely lit not just well lit. You could probably get a tan under that many! If you want to send me a drawing I will happily plot out a scheme for you.

You won't get a 400 lumen lamp either - despite what the sellers say. Ask them for photometric data for 'delivered' lumens and see what response you get. Your mobile phone is capable of lasting 4 days without charging but never does if you follow....

Just to pour on some scorn (I promise to stop immediately after and just be helpful). This made me howl with laughter.

No ultraviolet (UV) light: Bugs and flies rely on UV light to navigate which is why they’re typically drawn to bright outside lights. Next time you’re hosting a garden party and your guests are complaining about the sheer number of flies in the vicinity, you should think about embracing LED lighting. Because no UV light is given off, bugs and flies are not attracted to LED bulbs – which means that you and your guests can enjoy your parties and gatherings outdoors pest free!
This is complete made up load of crap. Part of the problem with so called 'LED specialists' who are nothing more than opportunist bulb re-sellers.
