After finishing it and creating minifigures I uploaded it to LEGO Ideas which you can find here: Four-Towered Castle

It contains some extra information such as piece counts. Feel free to leave a support on the LEGO Ideas site if you like it.

3D Model view here on Sketchfab: Four-Towered Castle

The Full Inside view. Note that the castle is made in a "L" shaped layout.

The left/West Entrance. Notice the flaps that would allow archers/crossbowmen to fire through and take cover.

The inside side of the West entrance.

Entrance to the hall from the courtyard/bailey.

 

The alchemy room. With a  green substance in a flask and a chandelier below the tall ceiling. The certainly need a ladder here.

A tower with a wooden hoarding around it. Crossbows are stored here.

The armoury. Along with the stacked sword it has a bed for a soldier here as well.

View above the towers.

Better view of the catapult and the winch for raising the portcullis.

Turnable fire in the great hall's fireplace.

Winch which you can rotate the fire and exterior of the hall.

Drawbridge Outside.

Gate Inside.

Chest room.

Stone Sigil.

Walkway.

Romans with a catapult & Celtic Warriors.

 

Upper view.

Nice work.

Very good!  Judging from the design and details, it looks like you have studied castles quite a bit.  Romans vs Celts gives it a nice historic aspect as well.

Thanks!  Yes have been interested in castle designs and architecture for a while and wanted to eventually make a castle in LEGO.  I tried to include different structures style throughout it so each tower and area would be different and so on. Glad you like the minifigure choices.

I like this design a lot. Would love to see it in real bricks. Nice work.
