Hi Steven Rawlins, Designing your own house does present some challenges, I suppose it all depends where you wish to invest your money on what kind of results you end up with. I like the way the house relates to the games room, it would remove lot of the noise from the main house. There are a few area where you might consider some revision of your proposal. You have not stated the location of north, really to make comments orientation is a very important factor and it would help in further edits. Also where you are located would also help (if you are comfortable with the idea) as this can ascertain climate conditions and if it is on Google earth it may be possible to ascertain adjoining properties influences and climate conditions. I roughly estimate that your house is about 15 meters wide, with a roof at 25 degrees you would end up with a massive high roof, the trusses would be significant size and the cost of covering such roof would be considerable. Also a roof acts as a sail, and although it helps that the roof is at an angle, it still is a large area for winds to exercise their destructive force. Special consideration would need to be placed on holding down bolts, and it you are covering with concrete tiles it would be a considerable cost. I think you might like to revise this roof design and reduce span, weight and cost. There are three doors between the "inside and the outside" front door, back door and garage it means that in winter you heat all of the Kitchen, lounge, dining and corridor, this is a lot of area to keep heated in winter (and cooled in summer) your costs for heating and cooling would be considerable. If possible I would consider adding some doors to act as airlocks to reduce heating and cooling costs. The garage which is of good size, has a door opening in the living areas (close to the main corridor). In winter when the front of the garage door is closed and you warm up the car the exhaust fumes will find their way into your kitchen/family/ and the rest of the house. These fumes are generally heavier than air and will most likely be ingested by your children and your pets, furthermore this is an accumulative process which I feels is not amenable to good health. In the master suite you have to cross the room to get from the master bathroom to the walk in robe. This would become an area of max travel as it is an activity done at least every day and sometimes "wetness" is included in the mix. It would mean that the carpet wold become warned and most likely soiled, and if you have a hard floor it would become slippery. There is also some wasted area at the entry of the bedroom which you might like to reconsider. The three toilets shown in the proposed plan all have internal opening doors, these are not very functional (illegal in Victoria unless you have panic hinges) if you have to get to someone inside in an emergency you would find access to them very difficult and might damage them as generaly people fall forward in such areas thus blocking the door opening inwards. Changing to external opening doors or sliders might help to solve this issue. The robes in bedrooms 2,3 and 4 seem to be very small, and not very well located. In bedroom s 3 and 4 you might find it helpful to locate the robes in the wall between the two rooms with some rearrangements of the doors might give you more storage space and act as a noise suppressor between the two rooms. You have a very good storage for linen in the laundry, however this can at times be effected by moisture variation especially if the dryer has heavy use. As pointed out from others above the scullery sees to be very large and it might also generate a lot of traffic considering that this is the only sink in the kitchen. Generally we use a sink for washing up, cleaning vegetable, cleaning fish, getting a glass of water and sometimes in an emergency. Really a kitchen sink should be separated from the stove/cooktop by about one working station which means 800 mm to 1000 mm. This is because in an emergency (pot catching fire) we instinctively move the pot to the sink - quickly. Maybe adding a second sink to the main kitchen might be beneficial. To help in getting a better idea on the were space is misused it is sometime good to add the furniture, and this will show your circulation corridors and were you might reduced space. I hope these comments are of some help, generally it takes me three revision for me to get the Sketch plan to a point where the client has some acceptance of the idea, and sometimes a greater number. This part of the design process is the most important part, hopefully helping the rest of the documentation. Wish you the best for the future, I would be happy to further commend on this project towards a hopefully successful resolution. Michael Manias Building Designers - mm407p@gmail.com

from my experience extending a small amount is not necessarily cheaper than extending a lot and any extension means that you'll have to have plans made and a Development Application approved by the local council (and these two items will cost thousands before any renovating begins) and you will be very surprised how quickly your budget will disappear without very careful preparation ... a plan of the existing house and a wish list is the best way to start..in the meantime, what condition is the existing kitchen, laundry and flooring? could the old kitchen appliances and sink be reused? what about flatpac cupboards? could the work be divided into stages so that you don't run out of money halfway (eg could floor and painting be done later?)..why not post a floor plan with measurements to invite suggestions for the new rooms and i can draw up a plan with the total sq m for you

If the rumpus is going to be used as a family day care room, then I think the powder room should be accessible from there. This will make it so much easier for one person to supervise the kids in the room as well as the one who is heading off to the toilet. Perhaps you also need a wet area in there for cleaing up after messy activities. I know someone with a similar family day care set up, and they have toilet and laundry attached to the back of the garage/daycare space. And then the kitchen is adjacent, this makes life a lot easier for the sole person in charge of the kids.

Hi I have a large bathroom with a closet for washer and dryer. I love it. Off my bedroom. But also have you thought about making study into bedroom with an en-suite and the laundry tucked in there behind doors. If your selling a bedroom downstairs for an older person its very attractive and nice to be separate from the others. Then the two bedrooms upstairs have there own bathroom. Also you are having toilet tucked under staircase for visitors. If you had heaps of space then yes have a separate laundry but it’s a waste of space when you haven’t. I have my laundry essentials in a cupboard under my bathroom vanity which is 1800 cm long and still have two 1m drawers next to cupboard.
