Everyone had different abilities so always down to the individual if they are competent enough.
It doesn't mean they are belittling anyone's profession.
Apart from knocking 2 rooms into one, plastering and new downlights I did everything else.
The assembling, fitting of cupboards, routered the worktops to join and curve the ends to match the cupboards laid solid wood flooring, damp course membrane and thin padding stuff underneath.
Removed the pvc door and concrete blocked the inside and bricked up the outside, again with the relevant tieing in, damp course and insulating in between.
Cut out and fitted the sink and plumbed in new pipework removing all the old stuff out.
Fitted wall cabinets and under lighting, added new sockets when we realised we wanted the old door removed to fill with floor and wall cupboards.
Would I take it up professionally? Hell no as it nearly killed me doing it on my own.
Do I think I am now a professional, hell no.
What I do know is that b&q wanted £1500 to fit the kitchen design we chose, that's money I put to all the decorating/ tools that were needed.
Is it perfect no but it's pretty damn close.
No tiles, but I tiled my bathroom 4-5 years ago so that's ticked off the bucket list as well.
