It will probably be a material which will become dated. Given the number of programmes on TV dealing with renovations on limited budgets (not the rubbish ones where it is a game show in a different format) it is becoming a 'fad' material so in the future a plywood interior will be dated to the early 21st century. The material just like colours will go out of favour and back again in cycles.

Thank you siriuskey :) The location is metro Adelaide so very hot summers and cool winters. Plans are for timber frame wall and roof construction, rendered hebel panels for all external walls and colourbond custom orb roofing. Party wall construction with 25mm gyprock shaft liner panels. Laminate timber flooring for living areas, carpet to bedrooms, tiles to wet areas, stone bench tops. Exposed aggregate concrete driveway & front footpath, grey concrete/paving to side path & pergola area. The market for these homes is predominantly downsizers, first home buyers and possibly single/separated parents with young children who do not want a large block of land. Basically nicely completed traditional/modern homes with above average finishes but not too high end.

to access the power point through a backboard cut a matching hole in the backboard to access the power point and add a small extension cord to have the power in a more convenient location but storage depends on what you need to store but try the PAX wardrobe (1500 wide x 2100 high) with extra shelves plus a freestanding chest of drawers eg Malm 80 wide to leave a small gap at the window wall for the blinds and use wall hung open shelves and don't forget to secure the wardrobe and drawers to the wall...if you prefer the chest of drawers to be the same depth as the wardrobe you could add an extra counter on top of the drawers (Ikea and Bunnings sell custom cut counters in various colours but consider having the chest of drawers and/or the wall shelves in different colour for constrast and matching knobs or handles to doors and drawers

My thinking behind moving the Scullery to the outside wall gives direct access from the garage into it and the kitchen which could also have a servery to the alfresco, but also to avoid a long narrow passage way entrance between the living and family room which closes it in The only wall space between the living and family will be the depth of the fridge, which going by the floorplan still protects the room I have as a dining/study if you maintained that wall
