Canopy and Undermount are best, and need to be ducted externally. Which one you go with will be largely determined by your design and joinery choices.
What you should be paying…

This is a really good example of one of the many differences between the building methods employed by a project home builder and a custom home builder, and why you…

great thanks i will try foam backing road for smaller gaps as DIY
will the have bigger in size for bigger gaps?
I think it goes from 6mm up to 15mm

If using expandafoam use the low expansion variety as I´ve been told normal stuff can add too much pressure. Filling it will help achieve better air tightness and add some…

The stainless or aluminium are both just veneers of the product stuck on moisture resistant particle board. It's not solid material, so it's no different to a melamine or similar.…

It's purely a matter of aesthetics.
The brushed metal kickboard look was popular some time ago but the majority of people now just go with a matching colour kickboard to the…

put the 2 draw set directly under the cooktop and the 3 draw set either side for balance

For the outside Aluminium angles are standard. Inside you can fill with expandable foam for larger gaps. Smaller gaps say 10mm and under you can use sikaflex

that’s in the wall, it’s more about the trap and basin location within the cabinet. If the basin inset or the trap is sideways there is less space within the…

Pulse is correct. It's the trap that takes up space.
The plan shows a vessel style basin so you don't have to worry about a basin inset, it's just the…

Bigger the better for storage for me IMO.
But I guess it's harder to tell the cost/benefit in your example - mainly the 'cost'? If you go 700mm, what are…

That's a bit of a vague question. Either cupboard size is fine. With no real advantage or disadvantage to either, apart from the fact that the 900 cabinet fits more…

Like pulse said, you can fit drawers however because of the placement of the sink there isn't much depth so you would have to have cut outs for the waste…

Shelly switches require a paid subscription for full access to all features which is ridiulous given the lifespan of a home and if you were to sell it or buy…

Bit tricky, not enough room for two drawers either side but a pipe cutout might work with one big drawer. I did a few in my kitchen.

Internal tiles and external tiles are slightly different.
Internal tiles can be a smooth finish.
External tiles, can be slippery due to rain, water, dew etc so they are they are required…

Shouldn't your frame covered from the outside before you put in insulation into the walls? And yes, you would have to put insulation in between joists too.

Sorry, don't know costs, but there are a couple of very important principles you need to get right (and now) ....
(1) never agree to any "upgrade" unless you first know…

Insulating internal walls is a good idea - I always do it. Helps reduce noise transmission and helps with thermal insulation.
Do you want thermal insulation or acoustic insulation? It makes…
