During renovation, spend sometime to do your own inspection, just to ensure they are using the right material e.g. solid plywood with correct thickness, laminate with correct thickness, hinges, wall hung cabinet fixed with sufficient bolts and so on.
After completion of work, you may also check hinge (easy to open and close without extra effort), brand of hinges if you have paid for better one like 'Blum' system, rust stain on hinge, gap between cabinet & cement base/wall fully sealed by using sealant/sillicone, installation of cooker hob not too near to the wall, no scratch on your kitchen work top. Check finishing inside the cabinet/wardrobe e.g. no delamination of board & laminate ....
