mmm how to explain. I went through about 12 id around sg. Some better known ones some not so popular ones. All went exactly same specs except kitchen (original idea was a very simple kitchen) I have a total budget of about 80k for this reno. Without appliances and the modular wardrobes, the quotes ranges from 55k to 80k, as there is quite a fair bit of work to be done. Bear in mind its all the same design specified by me. I already know what i want. Everything was hacked away including windows and doors + door frames. I did it all the above including a much upgraded kitchen at about 40k including wardrobe. breakdown in costs as follows : Approximate costs Hacking, tiling, plastering of walls : $15k Kitchen $11k wardrobe $6k Pipping $1500 Electricity $1000 toilet doors : $700 windows : $2800 doors : $3000 +/- about 40k but i get a much better kitchen and wardrobe system So balance budget goes into buy better things I am strong believer of paying for what the family uses often.
