Hi stashing_it,
Good to hear you're thinking about building! We are in New Zealand, and built an eco-home on a rural block, so our situation is different and costs aren't equal, as building is expensive in New Zealand.
What we did to save money:
- my dad is a builder. He came up and lived with us for four months and did the work for free. We worked as labourers on the weekends and husband took some days off to help. I project-managed.
- my husband dug and laid our driveway himself.
- We did a lot of jobs in a labour-intensive way to save money - for instance, our block walls are filled with concrete for insulation and to provide soundproofing (part of our house is a music studio). You would normally hire a concrete truck and a pump to do this, but we mixed the concrete by hand - several tons of it, and got a few friends to help us lift it and tip it into the walls with buckets. It took 3 -12+ hour days of intense work, but we did it. Saved us about $4000.
- We hired a draftsman instead of an architect, and did most of the design ourselves.
- Our rough costs were $215k for the land, $100k establishment costs, $149k for the house (approx. 100sqm). No garage, no landscaping. We're building another 100sqm extension in a year or so with a garage, etc.
- We built the kitchen ourselves for about $2500, including the oven. This to me is a big win as kichens can be expensive.
- paint walls (int and ext) yourself, and do your own tiling, are easy wins.
- We did a lot of cash work with our tradies - saved us a bit off normal prices through not paying the tax.
- outlet stores, specials, coupons, discount cards. We had a farm card that gives us rebates and discounts at a lot of stores. This saved us a serious amount of money. Also, we got trade-prices on most materials through Dad that wouldn't normally be available if you were self-building. We tried to pay for a lot of odd-and-ends out of our regular household budget - so they didn't come out of the mortgage.
What we did to make an awesome home:
- We hyper-insulated. It is amazing. Do not skimp on this. We wanted eco-friendly wool for insulation, but due to the budget we ended up with ordinary batts.
- double glazing. Not common in NZ, but so so so worth it.
- off-grid. We have solar power. Our neighbour designed and installed our system, so we got a $50k system for about 1/2 that price. No power bill ever again. Don't have to go off-grid but I do recommend designing for solar PV and hot water.
- The high-cost rooms are kitchen / bathroom and extra rooms with special needs like music studios. Focus on shaving costs off these rooms, rather than, say, cutting space out of bedrooms and living spaces.
Mistakes we made and things we learned:
- Our biggest mistake is that we didn't have a planned, itemised budget. We didn't get a quote from our builder because there was just no need. We didn't sit down and cost out EVERYTHING and figure out what the place was ACTUALLY going to cost. I had a figure that I wanted, and said "This is what we have, and so this is what the budget is," but, if you watch any amount of Grand Designs you'll know it doesn't work like that. I mean, we costed things out like the roof and the materials and the windows, but as you go there are 1000 little costs and extra bits you add and everything ads up. Shower doors, laundry tub, porch lights, spouting, 100 trips to the hardware store for bits and bobs. It all adds up. I am extremely frugal by nature and we got a lot of stuff secondhand or for cheap off TradeMe, but it was tough. We were $70k over the figure I wanted to spend.
- We started drawings in Sept. The draftsman said, "Oh, I'll draw these plans up in 2 weeks and council consent will take maybe 6 weeks. We think, "Yay! We can get started over Christmas and finish by May!" Instead, we submitted our drawings to the council in Jan and it took them till May to grant consent - the week before my dad left for his 4-month OE with my mum. So we finally moved in Christmas Eve of the following year - 8 or so months late. And all this time we were paying rent AND a mortgage on the build. So my second-biggest piece of advice to people considering building is that the schedule you set is not the schedule that anyone else will keep. And that council SUCKS.
- turns out digging and shaping a 200m driveway requires a lot more finesse than we had anticpated. So, after weekend after weekend of renting a digger, sourcing stone, digging and shaping and compacting the thing, including $2000 of repairs to a digger and a fence after my husband introduced them to each other, the driveway didn't really "work" and we had to pay another $6000 to get it re-shaped professionally. Expensive lesson learned.
- establishment costs (driveway, sewage, solar panels, trenching for internet cable, water tanks and pipes, etc) cost more than $100k.
- $10k of our budget went on soundproofing my husband's music studio. We could've spent a lot more. Some of what we did worked exceptionally well. Some of it maybe wasn't necessary, such as paying extra for sound-insulating batts. But it works and that was the important thing - it was a bit of an experiment.
- we would've made a lot more mistakes if we hadn't have had my Dad - a dude with 45+ years experience in the industry - there helping us.
Cost it out PROPERLY before you start, expect it to take longer and cost more than you expect, especially if you're doing it yourself. And TRY to have fun, because it is awesome, even though it is stressful beyond belief! I hope this helps!
