What house use only concrete wall, not cement rendered brick wall? 

Most flat or low cost house is using material so called hollow concrete block. Well, I'd say not really concrete like pillar or beam 

Most hammer drill will do. What is your budget? I think many experience people in this forum can advise you.

With 1.5k budget thats a lot. 
You can buy one rotary hammer for drilling holes in brick/concrete and one drill driver for screwing and drilling holes on wood/metal.
Got enough money to use cordless version too haha.

example combo set.

You will need cordless version if you plan to do things like on the roof, in the ceiling or outside the house where pulling extension cable is a hassle.

Normal hammer drill is not that expensive. Nowadays most have speed control and advertised as it can be used as driver as well, but I think you are better off  with separate driver. More flexible with torque adjustment and more precise speed control.

These is what I just Googled. Even if you buy both, it is still way below your budget. If you buy no known brand, even cheaper

Instead of hammer, this is rotary hammer which is more recommended by many here. It has 3 functions; normal drill, hammer drill and chisel

For driver, I'd recommend cordless one and this is not bad price for brushless motor which is popular now because can last longer and no need to replace carbon bursh (wear and tear part)

I'm not a Stanley promoter  , but the good thing about them is Stanley has 2 years warranty. His bother, under Black and Decker, which is more for occasional DIY like you has 1 year warranty usually.

You can search around. There will be other shops that sell cheaper, but probably some come with no casing and something like that. Just double confirm. You can also search for other brand if you like Bosch, Hitachi but they are more expensive but shorter warranty
