I'm doing some renovations to the rear of a double fronted Victorian house. I've done a diagram to depict the design i'm hoping to achieve, which is attached, as well as the original floor plan. I'd love to get suggestions on the design. Basically i'm trying to keep the front part of the original house as is, so I can still have three bedrooms and a possible fourth bedroom/living area and leave the original house largely untouched. I just want to add a bathroom, toilet, laundry, kitchen and living area on the back, and am looking for a way to do that fairly cheaply and quickly.
I have a carpenter who thinks I should try to keep most of the plumbing on one side, and i'm really keen to have a big, open living area where I can have a small (4 person) dining table, couch and TV.
I'm not sure how it will feel with the laundry, toilet and bathroom all coming off the living room like that - i've never been to another house with the same layout. I'm also struggling to visualise how big spaces will feel - is X big enough for a living area, etc etc... Anyway - if anyone has an ingenious suggestion to solve this problem i'd love to see / hear about it! Thanks.
