Thanks for the comments guys. Space available was 5.4m (Length) x 1.16m (Internal Width) In order to give it that complete luxurious look and feel without blowing the budget we had to improvise on a few items. Architect originally had specified custom make on vanity and a shower base which were a lot more costly and less aesthetically pleasing. 1. Vanity - Original price from architect and supplier Custom build - including basin and fixtures $4,000 Vanity was purchased from local hardware store off the floor with under counter basin a. Vanity - $899 b. Handles powder coated from chrome to matte black cost $30 c. Cut out under count basin and fix FC sheet under stone $18 FC sheet plus time d. Over counter basin and tap ware $450 e. Glue and caulk to secure basin $50 Total Price - $1,447 TOTAL SAVING - $2,553 These types of solutions can help save money and also time in sourcing custom products, if you would like more information please do not hesitate to contact us. We would also love to hear from you guys about any projects you have done or ideas. Smith and Sons - Williamstown

In some situations I imagine it's desirable to maintain the appearance of a window for the external aesthetics of the house or it's useful to leave a functional feature in place in case anyone wants to reinstate it in the future. I'm not sure that's the case with your window? Another possibility is simply to make the job easier which benefits the tradie but not necessarily you and cheaper which possibly benefits both of you. What ventilation and lighting do you have in the room? Personally I like the suggestions by Franca Comito and oskuee.

Appreciate the thoughts and this may be a solid option elsewhere in the country but in my circumstances I don't plan to be moving from this property any time before the kids are 18. It is located in Sydney's inner west, and in a specific high school catchment I plan to take advantage of when the kids are older. Stamp duty to buy the property was close to $100k and if moving out even in ten years to a larger property; that averages $10k a year spent on stamp duty. I know 115m2 internal is tight, as is the fixed layout due to existing bedroom walls, ceiling heights, wet areas, and the like - but there has to be a way to make this work... I have read that 4 bedroom apartments should be 102m2 or bigger. I am willing to make compromises where possible but I really want to create that extra separate room "Multi-purpose room" which can double as a study/work area/kids play area/media room/ad-hoc sleeping accommodation". Paul Di Stefano: I don't think these changes essentially equate to 'rearranging a sock drawer' - this is my PPOR so I am not too concerned what other buyers want or resale value if I plan to hold the property for 10-20 years +... (any trends we design for now may well be outdated by then anyway). Many buyers highly value indoor-outdoor integration. By moving the kitchen to centre, it opens up the rear and creates indoor living->outdoor living link. If I get IKEA flatpack kitchen and DIY as much as possible - have a friend reroute the water/drainage/+his licenced electrical friend...hopefully this work would cost sub-$20k. Adding the sliding door to rear is $2.5k. Ensuite, bathroom and laundry I believe I can fitout for $10-15k all up- let's say 15k (again, tiling, raise flooring, showers/fixtures/flat pack laudnry cabinetry install all done in-house without tradies). The only thing I really need professionals for is to move the gas line in kitchen, BIR installs, stone benchtop, and maybe a few adhoc wall demo/construction/doorway moving - lets call that 10k. All up ballpark that is 47.5k? Sirius- If I go with your style plan then I lose the potential 4th bed space and have no where for relatives to stay, babysitter, nanny; etc :( Maybe it is a possibility that the main living space be used for lounge room and kitchen, we can always put dining table in the Multi-purpose room, then when that room is needed for sleeping accommodation, the dining table be moved to the side and kids can eat dinner on island bench bar; lounge or outside table... ? those doors to each side of the fireplace as you suggest - this space is very cramped outside (2.45m width) and potentially would be used to store trailer or garden shed, there is an old terrace built on zero-boundary there and they have a DA to go 2 storeys; which will shadow the whole area. This is why I planned to make the rear south corner a raised deck and try to channel house activity leading out the existing glass french door to that deck, or the rear sliding door. See photo-(my house is on the left, terrace zero boundary on right, and front on is a wooden dividing fence which on the opposite side is the driveway/1 car park and front street.

there's not enough space to have any open shower the best option is the sliding glass doors but a shallow bench with semi recessed handbasin and mirror doored wall cabinets would feel more spacious than a vanity
