Let's fit 3 bedrooms and 2 bathrooms into the space of 2 beds and 1 bath!

my client is building a development of townhouses, and wanted each house to have 3 bedrooms instead of 2. the space is limited but I completely understand why a 3rd bedroom would be useful for families. yet, how can we squeeze a third room without it feeling like a prison? let's do some space optimisation and try to fit 3 full bedrooms without any one of them feeling awkward or cramped and even ensuring each of the secondary rooms still has space for a bed and desk! *this was not clear in the video but this is the top floor of the townhouse, so the little terrace/lightwell of the inner bedroom will open directly to the sky which means it'll be very bright!
