Home extension
Page 1 of 1
Try $2500m2 as a basic fitted out extension. This DOES NOT include any renovation of your existing house.
This was our rough idea with costs.
Add 100m2 to an existing 101m2 house (16yr old at the time) for a single storey or part ground floor part upper addon, including
re locate laundry to rear of new building.
Add master Bed room with ensuite
Add study
Add living room.
Strip existing Laundry and re model into walk in Pantry(shelving, cupboards, electrical included for pantry, not rest of kitchen)
Includes electrical fitting to new rooms.
Includes light, bathroom, kitchen cupboard fitting to match existing (old/tired)
Does not include
Floor coverings to non wet areas
renovation of existing house (kitchen, bathroom, walls to be moved/removed not required for extension)
excavation of land to allow extension (extra $25k with retaining walls)
Any provision for a garage.(brick garage to match house was quoted as $48-65k)
removal and re install of central heating if adding second storey.
One kicker was that they wouldn't match any new fittings if we decided to replace them with the extension. So if we wanted to update the tap ware, cupboard handles or light fitting they would fit the ones to match the old stuff, then we would have to replace them ALL.
Also we would have needed to move out for at least 3 months of a proposed 9 month build.
Kitchen renovation was priced at an additional $17k plus appliances to change from a "U" shaped to a "L" shape with island bench. No stone included.
Total costs.
$238,000 for extension
$25,000 excavation and retain
$5,000 floor coverings
$17,000 kitchen upgrade
$6,000 appliances
$3,000 remove and re fit heating
$x,xxx Rent
$2,000 new fitting for bathroom, new door handles through out.
= $296k (no garage remember)
We are about to start our knock down re build this month (house is about to be pulled down in Jan)and the total cost of our new 31sq house including garage for 3 cars is less than the extension price if we got evap cooling instead of refrigerated and opted for a lower grade of appliances (the ones we ot offered were OK but I wanted Bosch ones)
If you can Owner build you'll save money, but you really need to have the spare time to start with.
But out house is double-brick, inner city, stone fronted, character features, so knocking it down isn't an option for us. We might lose say $50-80K if we were to sell it straight away (which we don't plan to). I think you need to look at how much it's currently worth, work out what the end product would sell for and work out how much you can spend per sq m etc.
