Wuff, you wrote my bedroom memories of my room at our farm. Lipstick pink carpet and psychedelic curtains and bedspreads. I still think it was the coolest room I ever had! I am currently using 60's and 70's colours and patterns to decorate my fabulous 1965 built home, with a 1970 sunroom extension. Psychedelic black and white vinyl in the bathroom. The rest is white and beige lamipanel in the wet areas. I have an orange and cream geometric patterned quilt cover and pillow slips I love in my bedroom and found psychedelic lime, purple and hot pink , with white splotches linen for my guest room. I have a lime green glass splashback in my kitchen, with terazzo look minoleum floors and blackwood cabinetry, with butcher block benchtops. I kept to white enamel appliances for 60's authenticity, but did use a stainless steel cooktop. I also have 1960's canisters, two sets one ranges from tangerine, to pale lime, beige, deep aqua and salmon, the others have bight fruits, with black lids. My jug is electric blue, with a matching toaster! I have my original 1970's microwave and food processor, as well as a hand me down 1960's Sunbeam Mixmaster, with all its attachments! My laundry has a mix of cream and beige floral and lime green and more blackwood cabinetry and the benchtop matches that in the kitchen. My sunroom is resplendant with its spotted pine feature wall and lime green and olive cane furniture, with masses of much loved houseplants, including a hoya that occupies one wall, that is as old as I am. Both of us turn 60 next year! The whole house is painted in airey cream, an off white, that just takes the chill out of white white! My lounge is a collection of antique vases, fine bone china, silverware and blond wood lounge and dining furniture, all that were proudly displayed by my parents in the 1960s and 70's when antiques were all the rage! There is not a single tile in my house, by choice, to avoid mould and heavy duty cleaning! I hate cleaning tiles as much as I hate the colour grey! My place is filled with colour! Luckily the beige shot silk curtains that are the bedrooms and lounge are so neutral they go with all the ecclectic items and 60's era styling I so love. Their quality means they should see out at least a century of wear!

(my husband says you shouldn't misuse good tools on people) and my suggestion includes keeping the laundry within the bathroom with a 2.1 x 600 bench for drop in sink, under bench front loading washer and storage, removing the old back to back built ins allows both bedroom to be about the same size with built in wardrobes and using surplus space in the entry hall for multi purpose walk in storage. Keeping the laundry in the bathroom allows for a full sized dining table and good sized kitchen

based on the accurate dimensions the most economical update would be to replace the spa with a shower over bath, keep the existing vanity and toilet, reuse existing taps and retile but, any bath renovation is always much more expensive than imagined, and the unexpected expenses (eg asbestos under tiles) can add up and a minimum of ten thousand for a very modest upgrade wouldn't be surprising...If the bathroom is in acceptable condition especially if there's any possibility of a future expansion towards the backyard that could affect the current position of bathroom and laundry) i suggest (subject to confirmation from a plumber) that you consider reorganising the other spaces and sacrifice the wiw to create an ensuite with linen storage taken off the middle bedroom..surprisingly an extra bathroom could be less expensive than renovating the old one but i would still allow at least $10,000 with careful planning

A great outcome and so suitable for the climate. A subtle but to me big impact was how a lighter floor has made the whole space appear brighter and seems to have lifted the ceiling height. Owners must love the space now.
