When building a house what's the best type of block or brick to use?

I've lived in a house where I could literally pull out a nail from the wall with my hand (other houses in that estate fell during heavy rain), and in another where only multiple hits with a hammer on a concrete nail would enter the wall. I don't know anything about blocks and bricks, but plan on building on a land and would like strong materials only, also I heard red bricks are strong and keep the home cool during hot weather seasons. Any other cooler and stronger materials? I currently live in a house with red bricks on the outside, but I believe the interior is cement - normal wall nailing and some corners at the ground, between tile and door frames do break down into sand, but it's nothing near cool during this hot period.

Well as a builder I usually advice my clients to mould blocks by themself when building.
Becos the ones been sell by block makers are usually moulded at 45-50 pics per bags, instead of the standard 30-35 per bags. So that's one of the reasons while blocks are easily broken wen u hit hammer or just a punch self

Okay. So that's cement management, molding thick blocks. What are your thoughts on red/fired bricks? Also on fireproof?

Good day, as a building contractor i will advice to use cement and mould yr blocks yrself instead of buying the 50-60 per bag from those that sell as that is one reason most of the buildings now are very weak ,
