MeXXXcon homes true cost?

Generally display homes are around +40 to 50%

My last mexxxcom house was around 8% including
Site costs
Electrical upgrades
Wood panel kitchen cupboards (but formica bench tops)
A couple of extra walls and doors

Thanks for the replies. in retrospect from people who have built these houses what are the extras that they consider a "must have" and where does most of the extra cost come from is it upgrades or building costs?

The display house near us had over $200k worth of extra's, a lot over priced after going through the huge amount of pages listing them all. That was on top of the house price of $250k and didn't include gardens or curtains! For that price in extra's I would be expecting the curtains to open with a push of a button, ducted vacuum etc. but just a pretty house. I have been told they don't include toilet roll holders, towel rails, door stops etc. seems odd as they are part of a house.

We are in the process of signing up, going through Studio M etc now. For us we spent the most in building costs, we added a rumpus room, outdoor room and extension on to the sitting room. Studio M + tiles + electrical will come in around 50k, which is still a lot but that includes a lot of upgrades.

I have included some pricing on my blog http://thebirdslittlenest.blogspot.com.au/

I looked at Big M before ultimately deciding to go with another volume builder. The M display homes look wonderful but I found there were a LOT of things that weren't standard inclusions so the base price quoted was nowhere near what you would actually pay. For example vinyl wrap, sliding BIR doors were standard (think circa 1970's hotel room!) - that was in 2010 though so things may have changed since then.

TBH most people will upgrade/change a number of items in the house they ultimately decide to have constructed. It comes down to finding a builder that has most things that you like as standard inclusions and doesn't charge to much to change the other things you really want/like.

Good luck with making the choice.

@akashra: nope that's not the only reason I didn't go with Big M. As I said it was an EXAMPLE of the standard inclusions I would have chosen to change

Can't deny that BradS. We were originally getting a price for the 42sq version of the floor plan, but for an extra 16K we could get the 47sq. Where do you get a square of house for 3.2K? We live on an acre, currently in the worst house, best street scenario. Believe me, we'll fit right in! Not sure what the upperclass neighbors will say when they see a Mtrcn sign out the front though... Doesn't matter, they don't talk to us anyway!
