Hi, your home looks pretty good, you have done a lot on the interiors. Coming back to the question, yes, you can add a wallpaper behind the television, go for a textured wallpaper as it will create a compliment to your television. As you have decorated with wooden elements, you can go with a bookshelf on the wall. And, there is one more thing which will be a simple addition but will look perfect and that is an antique wall clock. An antique wall clock will make your wall look great without any fuss.

Australia has nice examples of painted and rendered Art Deco homes. If it was a different kind of brick I would say keep it, but I think painting/rendering would really brighten the place. I love the windows. Although all pics here don't exactly match your style, they are all of that era. As mentioned in above comments, there are mix of landscaping styles that suit from conifer/gravel/grass to cottage rose garden to an Australian native garden. Do what reflects you and how much time you have for your garden.

Hi there Nick, looking at your photos you look like a modern hamptons family which is lovely, do you live in a warm climate. I did like the photo you posted of the open plan living and think that you are on the right track with interior colours I have marked out how I would like the first floor, I have moved the kitchen to the end wall to line up with BBQ outdoor kitchen, plumbing for this would have easy access via the garage below. The white tiles look lovely and hard wearing for the entrance foyer and Rumpus room, the stairs in timber due to the amount of traffic even continuing in up stairs foyer kitchen dining living, Carpet in bedrooms and downstairs theater. Kitchen in white but possibly Shaker style white doors these are very popular. Using existing sliding exterior doors if possible from kitchen.Dining to verandah, I think this ceiling would be best kept white to help reflect light back indoors, the tiles appear to be in good order but you might consider changing these along with new upstairs flooring Some where for a laundry shute would be handy, actually a Dumb Waiter so you could move the laundry with ease both up and down! The roof painted a soft colour, grey/white or off white, the verandah railing could be the same colour or you could do glass. The builder had a very different style of house to what I think you are wanting. Your photo

DB.....A LOT of ideas and advice flying around here.......skimming through I see you are endeavouring to establish a basic concept for a designer/architect to consolidate for you, which is great.......whilst you may think this is a logical approach to achieve the best outcome, you are arguably just throwing around random ideas rather than properly resolving/focusing on the critical aspects ........my advice is do this: firstly clearly ascertain two things on paper, not in plan or building format but in writing...that is 1. List all your requirements/needs/goals and 2. Nominate a budget. Next, identify/research a logical local designer/architect option and approach them with this information....A designer's job is to come up with an appropriate concept/solution that best balances your requirements, aligned with a budget and of course make it viable within context/site. Sure, you want a cost effective/modest result, that's fine, and that will influence the solution, but as a general comment it feels like there is massive potential being missed considering the site..it dens;t necessarily have to be that big or fancy, but you have to put the EXPERIENCE of the home front and centre of the process, and not just think of it as a kitchen or whatever laid out this way or that ....This is about an amazing site and the living experience of that and the design should be based on this and bring together your specific requirements elegantly balanced in context......The issue I have scrolling through all this is that you have all these almost disconnected ideas of building form, but you have this incredible site....... the process of resolving the spaces ideally needs to develop from cues of the immediate environment/site in order to make the most of it since you are pursuing a customised solution.....agree with MB, every project has a budget and ultimately from experience this is in general the ultimate/overriding constraint. This project could be anything upwards from $500K and it will come down to the working out how far you want to take it, and what your priorities are over various levels.......this one has seriously significant potential -make sure you make the most of it as you're truly fortunately to have this opportunity to build a home for you and your family to enjoy there.......best of luck :) PD
