I think the 2-storey Semi D exterior does not look as grand as the 3-storey, it also does not have luxury features like top floor garden, jacuzzi, & outdoor shower. However, 2-storey Semi D is much more practical for a regular family and much easier to maintain as it does not have all the excessive luxury features as listed above. I think the 3-storey Semi D is not practical & will be hard to maintain for the following reasons:
- Double Volume Living Area - hard to change light bulb ot clean ceiling fan, aircond cost will be high
- Top floor outdoor area & jacuzzi requires lots of cleaning
- Top floor glass panel skighlight roof over the jacuzzi- soon the glass roof will be quite dirty, i don't know how you could clean it as its so high up, use a sky lift?
- Acoustic problem between ground floor living & first floor family area - living & dining area will be quite noisy if somebody is watching tv upstairs.
Having said that, the 3-storey Semi D definitely looks better if you are a regular party host. It also provides the 'wow' factor to your guests with the above luxury features.
Totally agree with u. Just ask those who has an existing double volume living area and they can share their experience with u.
