Hi, you have a number of questions I can answer a couple. As a starter, how do I find out 1) how much top soil I will need The amount of soil you need you can work out by multiplying the size of the area you are going to turf by the depth you want the soil. I think they put on around 2-3" of top soil on our lawn and levelled it off. The amount you need will also be determined by how bumpy your lawn is as they will need to remove lumps and bumps and then add the topsoil and level. I would advise getting a no obligation quote from a reputable landscaper. Ask them how much soil it involves. You can then make a decision whether you do it yourself or get in a pro. 2)Can I level out the top soil prior to building a deck - Or should I wait until the deck is finished before landscaping You should definitely build your deck prior to landscaping, it will also give you a better idea of what you are left to work with regards to lawn and garden beds. 3) for this amount of land should I be using the services of a bob cat person to level out the top soil I recently had my rear lawn re laid. It was a job we could have done ourselves as it is only tiny. It meant removing at least 4" off the top and then replacing with garden top soil (weed free) which was then levelled and packed down prior to ready lawn being laid over the top. The outcome is amazing but I don't have a photo yet. Word of warning, when working with garden soils, always wear a mask as my husband contracted Legionnaires disease from shoveling two trailer loads of soil into a retaining wall a few months ago. It is a very serious disease he was hospitalised for 8 days. They do have warnings on bags of compost etc at garden centres but never mentioned it to us at the landscape place where we purchased the soil. I noticed that our landscapers didn't take any precautions either. 4) do I need to destroy the lawn that is currently there before I add top soil on the lawn...Or can I buy soil and spread it on the existing lawn. You need to have the old lawn killed off as there will be weeds among it. I am anti sprays so we dug around 4" off the top of the garden, removing the weeds and roots, but there has been a few weeds coming up through the new grass now it is established so I would say for your large space to have it killed off in some way, then you need to remove the top layer and make it reasonably level for your top soil. With regards to ideas for your garden, you want to think about curb appeal, lead the eye up towards your entrance way. I know your entrance is off to the left so let your border follow the drive way on either side and up to your entrance. Make your entrance stand out with symmetrical pots I can't really advise a specific plant as I don't know your style. These are simply ideas to inspire you. You could fill the pots with white flowers that you change with the seasons or topiary to add some height. With regards to your fence boundary, it would be lovely to have some hedging although it can be high maintenance with trimming twice yearly. I am really into Ficus Tuffi (pleached) which is like topiary grown into each other forming a hedge. I am not familiar with what you can grow where you live but here are some border ideas. There are actually so many ideas, I could be looking for images all day for you, I suggest that with the great space you will have that you create a few garden rooms and focal points that lead the eye. I have added a link to my Landscaping ideas on Houzz. I am pretty sure they will inspire you. And although I am not a professional landscaper, I do have a passion for all design and when it comes to landscaping your garden you need to think about the style your house is inside. Also layering of planting is very important for example I have used box hedging then behind that a layer of star Jasmine and behind that an espaliered citrus tree which is against my studio. I don't have any photos yet but will try to get some up later this week. It is a brand new garden so you can see how a newly established garden looks like, not a five year old plus one as most of my saved images are. http://www.houzz.co.nz/ideabooks/63878109/thumbs/landscaping Layering.... Also think about height, plant some really lovely trees in areas you may want shade and something beautiful to look at. I love Magnolia Little Gem but there are some beautiful trees, I would use a mix of deciduous and evergreen so you get those beautiful autumn colours too. With regards to the front of your house you have some soil area in front of your fence. I would do some planting in front to soften the fence. Are you going to paint the fence? Plants will depend on the style you are looking to achieve in your garden, those above are more contemporary but you could go cottage but seems I cannot add any more photos so I suggest you look at my landscape Idea book (link above). Hope this helps and doesn't confuse you more :)

Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)

You could reverse the layout of the ensuite, and have the door to it through the walk in wardrobe (so you would only have one door coming off the bedroom). If I were you, I'd consider swapping the positions of the ensuite and wardrobe, so the current ensuite door becomes the wardrobe door. That way you could move the bed to the east (right), and you would have room for a seating area in the north west corner of the room (as your bedroom looks huge!). I'd also add a window on the small bit of north facing wall in that room; you already have corner windows in the living and another bedroom, so you could match those in style. Personally I don't particularly like the current layout of the main bathroom, although I can see the reasoning behind it (i.e. vanity at entrance, toilet hidden behind wall, window above bath). I think it might work better if you put the shower in the corner where the bath currently is (i.e. beside the toilet, opening to the west), and the bath on the same wall as the vanity. You'd have to move the window, of course. Alternatively, do you actually need three toilets? You could remove the toilet in the main bathroom, and you'd have room for a freestanding bath and/or a bigger shower. You could consider stealing a bit of space from the kitchen to create some storage at the entryway. I'm not sure where your garage will be, but it's really handy to have a designated place at the point of entry for all the stuff you tend to dump when you first come into the house (schoolbags, coats, mail etc). Overall, I think the layout is pretty good, but you could potentially lower the build cost by making it all a bit smaller. It's really worthwhile taking the time to figure out just how much space you actually need, and where you need it. For example, if it were my house, I'd take about half a metre off both the east bedrooms (so the house is shorter from east to west), plus I'd make it smaller north to south by slightly reducing the size of all three bedrooms, and making the kitchen a bit smaller (so the hall cupboard lines up with the back wall of the small living room). But your priorities may be completely different from mine!

Have you tried hitting up the place where you bought it from or had a look at the manufacturer's website?
