Yoongf, Thanks much for your comments To clarify, i got the shop frontage of part of a larger project; shophouse with a condo apartment erected behind it (part of my first floor is carved out for a common walkway) - the outdoor common area belongs to all but i guess i will be the one using it mostly - i could not have afford it alone otherwise Very helpful, in particular your points on the toilet and the laundry area Laundry is below the staircase connecting first and second floor; getting a combined washer/dryer so remaining space below can be for storage or iron 1. Lvl 1.. The long coridor to the back maybe inefficient use of space, and makes the place look narrow. Consider a glass wall instead? This is because that is the common passage way leading to lifts to condo units behind 2. Better to have a toilet on level 1. Using that area for laundry/storage - issue is because of the size of level 1 3. Lvl 2.. u got such a huge house, but the toilet is mickey mouse size. shd be way bigger, like 2 times the size. U can't even brush yr teeth properly as the side wall is too close to the basin. This is a restored project (so is brand new in a sense); would you settle for it for now or pay additional to hack down and extend toilet wall - i would so love to have a bath tub and tv installed in front of it 4. Take note of aircon considerations. When u on level 2 aircon, the cold air will all fall down to level 1 through the stairwell. Effectively u are cooling 2 floors all the time, same for the attic floor. Any ideas how to minimize cost? 5. Front courtyard can consider a nice koi pond or a raised outdoor jacuzzi in lush landscaping. Common area for all, but there is a pond - i intend to get outdoor table and chairs (had so wanted a day bed outside ala potato head in bali style but no space) What do you think of having those butterfly chairs (ala dampsey PS cafe)? 6. Is there a laundary area? Underneath staircase connecting first and second floor 7. Kitchen appliance space provision also mickey mouse side. 750mm for fridge is really small fridge relative to house size. Getting a SMEG retro one-door fridge; can't help getting it despite the bad reviews 8. Basin dun put so near the stove. shd space out. Hmm space is the issue; have the preparation area in between the stove and basin? Weird? 9. Spiral staircase.. is very high point loading on the slab below. Think need to get engineer to check if the lvl 2 slab can take the load. the cost will go up substantially if u need to do transfer beams/micropiling. Oh; who should i look for? This A&A structure i am still thinking if should obtain permit for... 10. Kitchen area.. take note of cross ventilation. Air can come in from the front, fumes need to exit from the rear. Should be ok i think 11. This is a house. Toilets shd hv natural ventilation, can even be bathing outdoors! I so wish
