Can you add dimensions please. Would you consider relocating bathroom to bed 3. Then an office can overlook garden. Combine bed 2 and most of 1 for master. Possibly some can be used for and office or guest room

Is the house on a concrete slab or timber floor? Makes a big cost difference if changing plumbing. Is the carport under the main roof?

Carport is shown as under the main roof

Thank you! We only have this picture of the plans at the moment. I have requested the full plans. We bought the house from a video tour as we don't live in the same state. The house is for us to live in (2adults no kids, both work from home). No plans to resell, but we don't want to 'over do' the property either. Our key concern is access to the garden/pool area. We also don't want to do structural as we have to get council permission if we change the footprint of the house ,and we want to move in fairly quickly. So ideally moving the inside only. It's on a concrete slab. The carport is still a carport, not enclosed. Which suits us as it will a good 'clean off 'area as it is by the beach. Not a city property, 45minutes from big city by the ocean :)

I have added a shower to bathroom in this option by moving the hallway into the adjacent bedroom which becomes a smaller office. relocating hall cupboard into the extended laundry allows the shower to go in its place using hall space as well Because of the access to the front bedrooms suggest you use the smaller room as office during day.

With the home being double brick and concrete slab, then wall removal and plumbing changes would, in my state WA, classed as structural changes. Also, if the works are more than $20k then they need council applications submitted.

subject to confirmation of measurements and structural limitations my suggestions would be to sacrifice bed 2 to create a better ensuite and wiw for a more comfortable master suite, add biw and use any of the other three bedrooms for your offices and guest room, (apart from repairs and cosmetic improvements) make no changes to bathroom and powder room, upgrade laundry to include tall storage and a counter with underbench washer and dryer with a drop in sink to create a "vanity" for the pwdr and nicer public access to the pwdr and backyard, adding some extra taps outside would allow for an external hot water shower and, depending on orientation and climate, add some skylights to brighten up any dark rooms (eg illume or Arcol Solar skylights would be ideal for hallways and Velux roof windows for bigger rooms) but there's not enough space to have such wide external doors to the backyard with so many other doorways and windows in the original kitchen without losing too much wall space so i would lose the door between entry and kitchen, possibly widen the doorway between living and kitchen/dining and add new kitchen cabinets with DW, stacked wall oven, MW, wall cabinets, big fridge and free standing island and avoid changing external walls except to use a minimum width sliding glass external door from dining room to a generous alfresco

THANK YOU!! These are all great options.
