Hi.. my house is done by Mr K too... I should claim that I am the 1st one here to get him as an ID... I shifted in for 1.5 years already ... so far so good... not much issue .... As for your questions... Is there any 'hidden cost' on the basic packages??? There's whole list of itmes from wet work, to kitchen, to plumbing, etc. Is there any things i should look out for? - I should say that there is no hidden cost... everything is written in black & white... Any problem cancelling items that's isted in the contract and reduce the total $$$ (after signing)? I will suggest those items that U are not sure whether U want to do... put it as optional... that was what I did... U can lock the price and make the decision later... Will the $$$ keeps adding up during the reno process? of course if U add items along the way.... U have to pay lor... Is the laminate design outdated??? Is there plenty to choose from? I choose the laminate from the booklet... if U are asking about the brand... I am not sure how many type... but if U are asking about the pattern/colours... I should say there are plenty... To be frank... I quite envy Cheesecake... I don't really have so much free things from Mr K hor... of course there were some small items I got it free too...
