Adding house extension(kitchen)& renovation - any tips?

[Prizen]

Hello all
1st post here. Just bought a house which is to be extended, and renovated. Based in Ireland, and unfortunately have no friends or family with expertise in this area.
I have uploaded the house plan. The extension to the rear is a kitchen, and we will make no major alterations to the existing structure, only tidy up. We will however install two new showers, one upstairs and one downstairs.
I have also attached a quote which we have been provided with, in € I’m afraid.
Any tips on what I should be looking out for or questions to ask about the quote? Should I be looking to install other equipment now to future proof the home? For example, LED lights controlled via wifi etc?
Any comments at all are welcome
Cheers!

I have two showers that run off a megger flow with no probs at at all so as above would not go for full on electric. Are you having plumbing updated?

Thanks again very much to all. So, if not electric showers, then pump boosted from the cylinder? Ok during winter, but during the summer when no stove or heating turned on, dont we need to turn on the immersion? Does this work out more expensive? I agree with the electric shower comments in general, but aren't they convenient for instant heat?

Talking to plumbers also, yes. On the plumbing front - we are having a new hot water cylinder dual coil, new oil burner, new stove with back boiler, new rads for the extension section.

I don't want to detract from your original request and there will be others on here far more qualified to comment than me.
My system is gas boiler which heats hot water in water tank in what I believe is called a 'Megger flow'. Hot water is pushed through at mains pressure which means showers only have to worry about flow and temp regulation.
Obviously your plumber should be able to advise on best options. From your specs you look far more organised than I was when I had an extension built. Spark turned up and asked what I wanted and I had to run round the house quickly marking where I wanted sockets and lights. Not good. Good luck.

I'd be supplying your shower from your new hot water cylinder if I were you. It will almost certainly be cheaper to run than an electric shower and far superior. What you'll need to do that will be a question for your plumber. You may not even need a pump depending on your system.

Re turning on the immersion, what will you be using for hot water for the kitchen sink/hand basins?

Thanks for all the replies! Was thinking of installing these new Philips LEDs that are controlled by WiFi. Anybody got experience with these?

Philips Hue lamps can be retrofitted into any property with wifi - so I wouldn't be worrying about these until you know if you will have any money left over. Neat gadgets but expensive and I had a demo of a system from a client today.

Friggin Wi-Fi, whats wrong with a light switch. Apart from trying to convince burglars you're home, and turning the heating on before you get home, don't see the point. Some computer bod just making money out of you.
