Hi guys, any architech or draughtsman who is familiar with dealing with mpkj?

Just bought a corner lot terrace. Previous owner did submission for renovations (rear extension) but did not apply for CCC. Probably not built as per plans.

So now since I want to do the following:

Extend gate pillar and change new gate
Lay tiles for car porch
Awning for car porch and side

Was thinking get drawings submitted as built and include my intended reno and get the ccc one go.

Should be no problem to get release letter. Seller’s relative so can get seller to help.
