hey bro, I think you have to be a little more specific...

1. Seal existing door and hack the wall beside to build a new door (basically change door location)
- it depends on the type of doors, size and the type of floor. (applies on both new and existing door). From these info, we are able to gauge the amount of work (greater effort is required if it is to remove an existing security door), the type of protection to cover the floor from falling debris (hacking and removal of door & frame) in the event if it is easily scratched floor material like marble or wood surface. May either use on canvas or 3mm thin plywood pending on floor material. It should cost approx MYR 3,500 (not including door)

2. Hack 2 walls - 100 sqft each
Total demolition on non load bearing wall. This is approx MYR 4,600 (including touching up the wall connecting edges and disposal of debris)

3. Paint whole house
This depends on
- house built up,
- types of terrace house
* intermediate (the usual)
* end lot (with gable wall that goes up all the way to the roof ridge but no additional perimeter wall)
* corner lot (with gable wall and perimeter wall)
* air well (high or low)
- Type of paint on external wall (regular or performance paint - with greater resistance against fungus and mold)
- No of paint combination (singular white colour, double coloured paints or etc)
- Any surface repair work on existing plaster (need cement rendering for external wall or skimming on internal wall?)
- Empty or tenanted unit? (additional canvassing and moving of furniture may affects work progress)
- Does roof tiles need to be rewashed and repainted via airless spray?

4. Change current plaster ceiling to a fully covered plaster ceiling (new lighting I guess?)
- Will need to know your total area

5. Renovate masterbedroom's toilet by changing a new basin, relocate the toilet bowl and bathing area (add a glass)
- will have to check out your existing bathroom for the following;
* single or doubled tiles (irresponsible renovation by previous tenant will cause additional hacking on wall and floor)
* change of water piping network involving copper or PPR piping instead of PVC
* small tiles (smaller than 1' x 1') or regular tiles (2' x 2' or 1' x 2')

6. Built in wardrobe (10 x 6ft)
- Melamine or laminated plywood?
- Type of finishing
- compartment
