Analysis first, then plan, as Tookoo recommends. Use native plants, as neotoma recommends. Get specific plant recommendations locally, as Terri & sgelade recommend. Here is my two cents worth, for the shortterm. a. Remove and stockpile the lawn edging and most of the mulch back against the fences. b. Take a can of spray paint, or a bundle of surveyor's flag, and mark the largest circular or curved form that will fit within the fenced areas, no matter where the trees stand (inside or outside of the line) to form the temporary edge of your lawn area. See if the entire family agrees on the alignment or just do what looks best to you as the Senior Gardener. c. Add the wood edging to the new edge, or, it will look a lot better if the edge is not visible, using a steel edge whose top edge is down just above the grass roots and no longer visible, and not an impediment to the lawn mower. (when you form the plant beds, you will dig down a couple inches at the edge, where it meets the steel, and then slope the bed up from there, and the mulch will be contained at the level of the lawn, beyond) My recommendation, after you call in your landscape advisor, is to fill the beds totally with ground cover, beneath the shrubs, so no mulch will be seen after the two years of plant growth, using only a finer textured mulch which will become part of the soil bed. (Maybe the bark mulch will smell good in your new fire pit, along with the wood edging.) d. Plant the entire area with grass seed or sod and enjoy the beauty. The curved edge will make the space appear and feel larger and will decrease the maintenance of the smaller bed areas. On the subject of tree placement: analyse first, then plan. Look at all the views beyond your fenceline from all windows of the house, the living/ dining areas, all the bedrooms, to enhance the good views and to block the big, the bad, and the ugly. The large trees on your list will block views from the upper windows, The small horizontally branched trees will be a piece of sculpture in your downstairs view throughout the year, while their flowering and fragrance yet another reason to be alive. For instance, if you have an attractive small tree that has attractive flowers and foliage, PLUS has attractive bark color and has a sculptural quality in the off-season, you won't have to visit the museum quite as often, with a sculpture garden right out your window.

Yes, all the Houzzers have been extraordinarily helpful. I am sure in the end, it will be a beautiful room. With regards to the change of sofa style, I was unsure of my ability to keep the white leather clean - particularly the stitching. By finally going with the "Julio" it is slightly more comfy sofa than the "Ariel". It has a higher back and I feel the "granite" colour will give me less hassles. In reality, the "granite" colour has slight yellow/creme undertones which tie back better with the curtains but this doesn't really show up in pictures. Golly, I hope I am on the right track. Thanks everyone for your help and suggestions. Keep them coming please

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
