DIY Kitchen window brick-up - Real Home Renovation

About me:
I'm a DIYer who bought a 1930s 3-bed semidetached house. With very little money in the bank for renovating, I decided to give it a go.
This project:
This window brick-up ties into the kitchen and extension build projects. Due to the new design for the kitchen diner, we need the wall space for kitchen cabinets which unfortunately means the window has to go.
Luckily I saved the Imperial house bricks from the old extension demolition, so they should match up perfectly.
This is a vlog of my journey, it's not intended to be educational, but I hope it helps others who always want to give big projects like this a go.
