I will put measurements for my pantry and vac on tomorrow morning. This image might look slightly different to his latest plan which I uploaded earlier he has altered a few things overall still same footprint. I'm pretty new to anything to do with designing house plans so thanks for all of the suggestions and plans so far. I definitely like the way you have narrow shelves for storage in your pantry. but

my program is a vintage 3D Home Architect version 4 that i've been using for many years and i believe is no longer available but Siriusky has recently acquired a similar program ...i didn't mean "level the house" i meant add a raised timber floor to match the living room floor with the rest of the house...and, when costing your project make sure you do comparisons of all the options to consider best value for money spent...is the property for renovation and immediate resale, for your own use or for immediate rental? each option should have a different plan and a different budget and you need to cost each option to make the best decision and the suggested kitchen is a simple one line DIY flatpac with a simple island table and should be considered against the extra value of the third bedroom

if i've understood correctly there's a driveway on the eastern side of the house? so my first suggestions is to make the deck as close to the boundary as allowed (hopefully about 1-5m from the fence will leave at least 4 m with stairs moved to the outside edge and create a drive through carport with potential access into the garage downstairs and a good sized deck space upstairs... i wouldn't change any of the sliding doors or windows and concentrate on making the best deck for the outside living area and use old dining room as a small TV room, old living as dining area (an extendable table can move indoors or out for big crowds) a generous new kitchen with island and open up the space between old living and kitchen without removing the whole wall

it' not the size of the toilet that matters, it's the size of the humans that need to use it ...allowing anything less than 80cm x 80cm for knee and elbow space, plus more for standing room plus extra for any swing doors and more space for a handbasins and with no other toilet on the ground floor the best option is a separate toilet and i would steal some space off the laundry to make a more comfortable powder room..and the different floor levels don't always prevent stealing some space off the laundry but what is the size of the laundry, including ceiling height at the wall closest to the back of the existing toilet and is the laundry ceiling flat or raked and how many steps are there between lowest floor and bathroom floor?
