They have probably done there calculations with a few concrete blocks under the bed to get the balance right.But seriously it's the actual layout which gets me thinking.
a)Daylight in living area (leave door open at all times)
b)Can you imagine not looking at sunset's/rain sat looking out of front window.
c)Where does the table fit (for grandson colouring on rainy days)
d)TV location? (for grandson getting ready in the morning)
Maybe I'm being a bit harsh as it is only the two plus one birth.
But I do think it will be very claustrophobic.My opinion only and I'm sure other people will love it!
Thats even if it exist's (Stealth=invisible)
