Under Stair Storage and Reinforcement

[PolarNorth78]

Good Morning,

The previous owners started to utilse the space underneath the stairs as storage and I want to open it up a lot more. I have the following challenges:

1) The stairs creak underfoot.

2) You will see from the images its a mess and the classic a block of wood and more nails will do the trick.

The go to support method is a piece of wood in the middle straight to ground. I would like to remove these so I open up the space for boxes and so on. The supporting walls are made out of dense block and the stair floor is hard wood. The property was built in the 1970s.

Whats the best way to support the stairs and solve the underfoot creaking?

Thanks in advance.

Quality wood glue used to stick and screw blocks of wood where you think is a good spot.
I've done a few to fix.

Those stairs are probably built on site with nails holding together. Not the best but you can improve

Thanks for the replies. Seems like its a simpler job then what I was thinking. The only other thing is how to secure to the wall as I suspect I will make some bracing to support the mini landing area. Is this a case of using joist hangers and some 2x4 or similar?

RE using a company, this is the route I am trying to avoid for numerous reasons.
