When one becomes two
Here is a little insight of the journey of creating separate areas from one block of space.
The first step would be to plan where you would like the partitions to be, then you would carry out the dry-lining as well as tape & joint finishing to these partitions. Each partitioning project will have different scopes of work (e.g. calculating whether a door will be also present and wires/cables that may need to be thread through).
