It is Halo base which is based on the Halo video game .
There was 1241 pieces of Lego to put together to make this base, currently sitting on my shelf in my bedroom out of my small brother's reach.
It took about eight hours for me to make this over a four day period.
The hardest bit was the rocket ship which took six hours. It was very tedious to do.
It was great fun building this structure because I like making things out of Lego.
