I need a drawing changing for planning permission

I require modifications to a drawing for planning permission purposes. The current drawing illustrates units 1 and 2; however, I wish to reduce the size of unit 1 by half, thereby enlarging unit 2 into a single, larger unit. The revised drawing must adhere to an A1 scale at 1:200. I have uploaded the original drawing, with the new dimensions highlighted in red to clearly indicate the proposed adjustments. Seeking an experienced draftsman to implement these changes accurately and efficiently.
