You won’t be able to add a basic room ie living for under $120k. Is that in your ballpark? Just to give the plan people on here the scope on whether to stick within the current floorplan or if you have the budget for an additional living.

Yes definitely budgeting to spend $ on an extension. Thanks for clarifying!

in order to take advantage of northern light and to make the extension roof much simpler to attach to the original house my suggestions includes the new kitchen family room (with direct connection to the backyard at ground level) as a separate building that is connected with an entry mudroom link with steps to "upstairs" and space for a courtyard and gardens plus an optional alfresco to connect the extension to the carport/garage....alterations to the main house has a generous master suite, plus three other bedrooms, bigger family bathroom, TV room and study or playroom (with or without sliding doors to create privacy with an extra hallway)...enlarging the original bathroom is done by stealing space off adjoining bedrooms and the original laundry would make a good hobby room or garden storage space or mini man or woman cave with or without the original entry door into the house and/or external exit door and steps ...the new laundry is included in the extension with access to the rear drying area through the family room ..an extra advantage of this style of renovation is that the extension can be completed while living in the main house and all other changes can be made in stages as funds allow...

Love a mudroom link. This one’s in a great location for the carport and into the middle of the house.

Thanks so much for this oklouise! I like the idea of a standalone extension for staging renos - what sort of dimensions is that? Do you think it would be too awkward in terms of flow to have the extension off the old bed 4 instead to keep the extra bedroom closer to the bathroom?

@bigreader, yes having external access to the link looks good for unpacking groceries to the kitchen too!

the extensions is about 7m square plus the link so about 60sqm of new work plus renovations inside but there can be some variations within the same location but the placement of the link between original house and extension is very specific and the short answer to your question is NO!.... the attached plan shows that by using your idea the link will not reach the extension unless you swop the alfresco with the new family room and kitchen and then it's it's a long walk from the kitchen to answer the front door or use the bathroom (maybe you need a powder room in the extension?) and you would have to go inside the house or through the carport to be able to reach the backyard from the driveway and the old bed 4 isn't big enough to divide into a hallways plus separate bedroom/playroom sized room

Ah, I see what you mean - thank you for explaining!
