My parents own a 4NG HDB in Hougang (~1,000 sqft). We're currently staying elsewhere so this apartment has fallen into a bit of a disrepair. My dad plans to re-renovate this house completely - virtually everything will go! He works as a contractor so I can trust him to make the decisions & get a good deal for the most part. However, I prefer to live there rather than move out in the long term for various reasons, so it only makes sense that I contribute some input as to how I want the house to turn out, right? Problem is, I'm sorely lacking in any relevant knowledge seeing as how I had only recently started my first job. I want the house to incorporate eco-friendly & ageing-in-place concepts & technology in the choice of materials, design, furnishings etc. I am open to using home automation & other innovative new technology to support that goal. This is the big overarching idea, and that's all I have at the moment - I don't know enough to proceed from here. My dad is more of the traditional and conservative sort so if I want to do any of these, I'll most likely have to do my own research and pitch the suggestions to him. What I need help with is outlined as follows: What online resources would you recommend for me to get insights & ideas on how to achieve & implement my objectives? How can I keep abreast of the latest innovations and technologies for the home? What would be a rough ballpark estimate to achieve this? I understand it can vary widely, but we're actually still quite some time off from doing the actual renovations so it may not be time yet to consult interior designers and get actual quotes. Right now I just want to set a financial target to save towards so a recommended figure as a rule of thumb is good enough for me at this point. I'm still at the stage where I don't know what I don't know, so please be patient with me and ask whatever you want, to guide me towards giving the right info and asking the right questions. Thanks!
