Here are a few photos for inspo!

Because of the narrowness of the area, there is only room for the screening plant. And I would keep the edges straight - curved edging is cottagey, and would look totally our of place here. Your house is not a cottage. I don't like the suggestion of trees with trunks visible. It is a colourbond fence at the look of it. I hide these - there's nothing special about them I'm sorry. And views are in the eye of the beholder. If it isn't on par with the best view that you've ever seen, then make your own view within your garden. You'll be far happier in the long run. And if you have plants of varying height so that the bottom corner is shorter in order to show the rooftops of neighbouring houses as a 'view', then the design within the garden will be spoilt. I know that there are those who think that lily pillies are common, but a plant that grows well in its position is far better than struggling to grow some uncommon plant that is a failure to thrive. I would aim for a lily pilly that is at least 3 metres tall. Consider Acmena 'Sublime' which doesn't get psyllid and doesn't need to be hedged if you don't want to. And I would run this plant the full length and around from the corner along the bottom fenceline. Your plants also would do better if the garden beds were 1.5 metres wide with the plant placed in the middle of the bed. Plants don't do well in narrow beds unless managed by a professional who knows what they are doing. As for the dwarf magnolias - these plants are dwarves of the Magnolia grandiflora which can get to 100 feet tall in maturity. So as a dwarf form, they still get up to 50 feet tall when they mature. The labels don't give a precise indication of height at maturity and are deceiving to novices. So don't go there is my advice. They also have bad root systems for so close to the house. You would also never be able to keep your lawn alive as they plants grow as they are water guzzlers as they get bigger. Nobody considers how plants behave once they are planted, but the care varies enormously with different plants.

my suggestion are based on the fact that mum and dad are usually at the house alone and aims for simple two person accommodation that can be rearranged to suit a crowd...the kitchen cabinets are the only fixed objects in the room and include a tall pantry, base cabinets and/or drawers with open shelves and wall cabinets and space for several people to work side by side with a small extendable dining table, two chairs and a bench seat (also used as a place for newspaper and lamp etc behind the recliners)...a patio with big table for outdoor eating under the shade of the tree with extra bench seats that can also be used inside... there's space for a small divan or night and day lounge with a wall hung tv and the corner bedroom door allows for much better circulation space in both the living and bedrooms with preferably a sliding glass door for indoor outdoor connection with or without the original front door and, based on the size of king single beds, there's no other arrangement that would allow both beds to have a view to the lake and there's just enough space for a biw, small desk and two chairs

Hi Lorna Lux, I think there are some serious issues with the layout of your house. Both the living room at the front and the family and dining at the back have circulation needs that restricts furniture placement. I would be good for you to put your furniture into the spaces and see how you will need to move around it. A large amount of the circulation is wasting usable space and you are trying to fit a lot into a reasonably small house, which as Dr Retro mentions, makes the spaces quite pokey. For instance, if this is a tight urban site, which it appears to be restricted in width, why not look at bringing the entrance in part way down the side of the house which would allow much better use of the front room. You can still make a really great feature of your entry down the side and it is cheaper to create that space outside rather than give over precious floor space internally. I don't think it is ideal to enter either bedroom 1 or 2 directly off the family, dining and kitchen space. Do the occupants of bedroom 2 have walk past the dining and kitchen and up the hallway to use the shower or bath? A bit of a hike. I have worked on tight 10m wide sloping sites in inner city suburbs and there are good solutions that only take a bit of fine tuning to make them great spaces to live in. Good luck, Christine.
