Sequence as follows:

Wetworks:
Basically means any extension or cement/concreting work. This is the absolute first thing to be done.

Electrical & plumbing:
Comes after wetworks or running concurrently towards tailend. This should include plaster ceiling lighting points. Plumbing is for any additional taps, inlets & outlets as required or installation of pump. Moving water main should be done at this point.

Plaster ceiling/Skim coating of walls:
Next in line for progress is installation of plaster ceiling as this can be messy. Skim coating of walls only if necessary or if budget allows.

Tiling:
After plaster ceiling is done in specific areas you can start tiling the toilets, kitchen or living hall.

Painting & door installation:
1st coat of paint for walls and plaster ceiling. If changing doors, these can start going in here. Door frames have to be installed before this point if being changed.

Installation of timber/laminate/engineered flooring:
With the glue and all being used, this flooring to be done last after aircond, lights, fans are installed.

Retiling porch, rebuilding gate pillars:
This is for finishing the outer part of your house. Basically the inside is more or less done. Installation of outdoor water filter.

2nd painting round:
Self explanatory.

Installation of built-ins:
Cupboards, kitchen cabinets, etc can be now installed. Tell supplier to not scratch your floor if using timber flooring.

Polishing of flooring (applicable for marble flooring only)

This is just a general guideline. Some of the items can be done to some extent overlapping with each other usually during tail end of each process. Time for each is dependant on your requirements. Hope that helps a lil.
