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

Hi Bonnie, What a beautiful kitchen. The overhead black glass doors look great. My thoughts are: Option 1, modern look: Black glass splashback to match the beautiful glass doors. I have used on my projects before, link below for your reference, and they work beautifully for a modern look and very easy to clean and maintain. https://www.houzz.com.au/hznb/photos/kitchen-design-monia-basso-architects-modern-kitchen-melbourne-phvw-vp~144827524 Option 2, industrial chic look: Stainless steel splashback to match benchtop. I have used on my projects before, link below for your reference, and they work very well for a industrial chic/or industrial modern look and, also, very easy to clean or maintain. https://www.houzz.com.au/hznb/photos/industrial-kitchen-monia-basso-architects-industrial-kitchen-melbourne-phvw-vp~144828526 My other thought is to keep the splashback height the same across the kitchen to align with the underside of the overhead cupboards, although you must check Australian Standards for minimum height for the area behind cooktop, this is a must for safety. All the best. I hope this helps. Monia Basso

I'd go the bright white of the kitchen on the risers , and possibly the wooden panels behind the lower steps -- the wall colour might suit the walls , but just me , I'd like to make the steps look associated but slightly different , referenced back to the kitchen .

have you personally inspected the property to clarify the available space as the real estate photos show that bed 3 is already being used for the living area so the property is really only two bedrooms plus open plan living dining kitchen and attempting to add an upstairs powder room would mean having the toilet open into the kitchen living area ..it may be possible to install a tiny powder room above the stairs (say $10-$20,000... if you could gain Council approval to do it) but another property with an existing upstairs bathroom would be more comfortable for yourself as well as your guests
