Oh yeah -- we started. Forgot to mention it

It's been a whirlwind. We had a design, then we got prices on what we thought was our final design. Then we redesigned our final design because it was tens of thousands over budget. Then we... well, let's just put all that behind us, shall we?

What matters is that we've broken ground. Not only have we broken it, we've made a big pile of it where there was no pile at all. Our excavation contractor dug the hole in just one day, and I stopped calling it 'the lot'  and started calling it 'the site.'

That was Thursday. On Friday we had the surveyors out to pin the footings, and this morning our masons showed up to form the footings. Footing inspection is at 10 a.m. tomorrow morning, after which we can pour cement and then start laying blocks.

We're going with a block foundation, which was a bit of a surprise to me. I'd just assumed we would either pour cement or use ICF, most likely the former as ICF is supposedly so much more expensive. But when we priced it out, we found they were roughly the same price, by the time you factor everything in. Then we got a price on block, which turns out to be roughly 35% cheaper. Apparently it's a supply and demand thing -- there are only so many people with forms, but there are all kinds of block layers out there and pricing is aggressive.

Of course, when you do anything with concrete in December you do it with one eye on the weather. We've got some good weather today and tomorrow (highs of 9 or 10 and lows above zero), but it's going to cool off after that. Still, with lows of -1 to -5 for the rest of the week, it's still above normal and shouldn't cause too much problem. (Or so say the masons). To be safe, though, we're trying to cover everything up with earth as soon as we can, to keep the frost from getting under the footings or the slab. That means making sure anything that needs to be buried near a foundation wall  -- phone, hydro, water, etc., along with foundation drain tile -- gets buried while the hole is open.

There are still lots of decisions to be made, of course. That part won't stop for months yet. But it's more exciting than frightening now. Last week, as we were readying to dig, I felt like I was sitting in the car on the roller coaster, looking up at the steep climb ahead of me and thinking this was probably a bad idea. Now the ride is underway and it's too late to do anything but hang on. And occasionally scream like a little girl.

Tweaking the design

We got the first round of quarter plan drawings last night. I was surprised at how many changes Phil had made from our initial sketches -- some good, others not so much.
Sharon and I spent an hour (after getting back from the theatre, so a tired hour) going through and making notes, then sent it back.
Somehow we're back to the debate about whether to have a high cathedral ceiling over the living room, a decision I thought we had made ages ago. Funny how that goes -- just when you think you've won, you find out you haven't!
Tree-cutting is going well. Only a couple of big ones to bring down, a few mediums, and lots of little baby trees to kill. Of course it isn't the bringing them down that takes the time, it's limbing, dragging and stacking. Isaiah was out helping me the other evening, and I'll get some more labour out of him this weekend. It makes a big difference, and almost makes it worth all the cereal we have to buy to keep him fed.
We had a couple of burns over the winter (well, one in the winter and one that was really too far into a rather dry spring -- a near disaster that I'm not in a hurry to repeat!). The rest of the branches are being stacked well off to the sides of the property with the idea that we'll bring in a chipper when the house is built and convert them all into lots of lovely mulch for gardens. Sawlogs are also being stacked for future firewood-making days. Thank goodness for a good Stihl.
Chainsaws, by the way, are one of those tools where it really pays to buy the best you can. I bought a $200 Homelight chainsaw from Home Depot, and when it kacked out even a staff member at HD asked me why I was buying such a crappy saw. I now have a $650 Stihl, which I love using. Starts, runs, cuts, shuts off, all when it's supposed to.

Decisions at last!

So many options, so many possibilities, it's been more than a bit overwhelming. But we've made some key decisions in the past couple of months, and we're moving forward.
Like 95 per cent of home builders in North America, we're going with standard stick framing. It's cheap, it's proven, it's efficient. Tempting as it was to go all funky with bio sips or rammed earth, this is just too big an investment to play with. I'll build a straw bunkie or a rammed earth shed sometime, maybe a hand-hewn log cottage, but the house will be 2x6 on 16 inch centres.
We've signed on with Rolston Home Building Centre in Huntsville. Their lead designer is an engineer with tons of experience, and he really enjoys helping first home buyers through the process. And he lives four doors down from our new home, so he's really familiar with the property. We handed over a deposit last week, and are hoping to have quarter drawings from him within a week or so.
Once we've got that done, we go back and forth with him to finalize the design, file the site plan with the town, and await blueprints. With blueprints we can then get final bids from contractors and get our building permit (after we pay gajillions of dollars for it! Honestly, the fees are an unbelievable cash grab. Permits and development fees will cost more than the well and septic!)
The plan is to start building around the end of September and hopefully get it closed in before winter sets in. I'm acting as general contractor and hiring our framing contractor to also be the siteman and coordinate the trades. Once it's closed in, I'll take some time off work (been banking a lot of holidays and time in lieu!) to do a lot of the interior work -- flooring, trim, baths, closets, kitchen, fireplace surround, painting, etc. I ain't doin' drywall, though -- you need to know your limits.
In the meantime we've been prepping our current house for sale (the upstairs bathroom is now unrecognizeable.... in a good way). I'm taking a week off next week, and will spend much of that time either working on this house or cutting trees and prepping the site on Cedar Lane. Will a change be as good as a rest? Ask me this time next week.

Ecohome

So last Friday I got a chance to tour the Niagara EcoHome with Ian Weir. Ian is the president of NatureBuilt, a company which makes Structural Insulated Panels using straw as an insulating material.
The technology is pretty cool: rather than building a straw wall and then plastering it when it's upright, you pour the plaster into a horizontal mold, then pack the bales in place, then smush more plaster on top. Once it's dry, you stand the panel upright, and hey presto, a section of wall. Panels can be as big as 8 x 10, and they're 16" thick. With an inch of plaster on either side, and a wooden frame, they're fully structural.
Like all SIPs, one of the advantages is that they're built in a controlled environment and then brought to the site en masse, so when you start building the house goes up very quickly -- just a few days and you're ready to put the roof on.
Unlike many green technologies, these walls also claim to be cheap -- comparable to stick frame but achieving R35+ with no thermal bridging and considerable thermal mass.
I'd looked into them a few months ago, and was intrigued but really didn't feel like driving to Welland to see the model home. But I had to go to Vaughan on Friday, which was halfway there, so I figured I may as well take the opportunity to have a look.
I was quite impressed. The system has many of the pros and cons of straw bale builds -- among the positives, thick walls make for impressive sound barriers; plaster tends to give a room a nice acoustic warmth; and air quality feels good. Thick walls can also make a house feel dark, particularly if the windows are undersized. In this home they've used good-sized windows, and expanded the flow of light by shaping the walls away from the windows. Unfortunately, the rounding gives it a bit of a Hobbit house effect, something we've disliked in other straw bale homes we've seen. Ian assured me that they can achieve a squared off look, or do an angled cut on the sides of the windows.
Because the panels aren't able to contain windows, window and door sections are framed conventionally. This is one of the potential downsides of this system, it seems to me: you're going back and forth between different wall types, between straw bales and conventional framing. The problem with that -- and here I'm wading into territory where I'm a bit murky -- is moisture. Straw bale walls, as I understand it, are meant to be vapour permeable (some call them breathable, but that seems to imply they're porous. It's not that air passes through them, but moisture can, very slowly.) That's why there's no vapour barrier, just an inch of plaster on either side. A conventional wall, though, has a vapour barrier. So you now have a six foot section of wall with no vapour barrier and straw insulation, adjacent to a few feet of wall with vapour barrier and window. So what happens to the moisture? Seems like there's the potential for problems there.
There are also issues with the look of the wall where SIP meets conventional framing. There's going to be a seam visible, which means you either have to plaster over both SIP and conventional wall (adding another step that requires skilled labour) or find some other way to bridge the gap. Ian said you can actually drywall over the entire interior wall, but I wonder if that doesn't work against the whole breathability issue. Then again, it would add more thermal mass to the interior, at a fairly low cost (you're bringing in a drywaller anyway to do all the interior walls.)

Exterior of the house. The walls have been treated with a skin of stucco. Note that they've decided to use the transition from SIP to conventional wall sections as a design feature, emphasizing the transitions with slightly different wall thicknesses.

Interior. The window ledges are deep but not outrageous. The rounded effect of the walls is something I'd prefer to avoid. This was one of the first houses built with this system, even though it's just opening as a model home now (delays in other aspects of the build, I believe). Ian said they've learned a lot about interior finishing since this one.

There are still a few questions to answer, but it does seem interesting.
There's much more information at the Naturebuilt site. CBC also did a piece on the overall project -- ignore some of the "gee whiz" tone of the reporter!

Update: Ian responded to some of my questions. See his response in the comments section, below.

BioSIPs

Structral Insulated Panels, or SIPs are touted as a great green alternative. They're thick, they're built in a factory so there's superb quality control, and they let you put the walls up quickly. There's very little thermal bridging, and they use far less wood than conventional framing. So what's even greener? SIPs with straw as insulation, or bioSIPs.
It's an intriguing idea. I'm going to tour the EcoHome in Niagara next week, to see if it's for us.

Yeah, it's been pretty quiet around here.

Coupla reasons for that. I've been busy working, and we're not building yet. But the bigger reason is that I've run into an unexpected reality: I'm not sure I want to share everything about building our house on a public blog.
There's a lot of personal stuff that goes into planning a build -- things like finances, and family squabbles, and personal assessments of builders ("did you count your fingers after shaking that guy's hand?"). So I've opted for silence.
But now I'm rethinking the blog, and thinking about using it as a place to muse on building in Muskoka, rather than on my building in Muskoka.
See, in the past year I've had an awful lot of interesting conversations with people who want to talk about building. Architects and builders, of course, but also lawyers and photographers and writers -- people who are just interested in what's being done and what can be done.
I was toying with the idea of having a Beer n' Building party, but I figured that wouldn't be fair to the people who actually know stuff -- we'd all be glomming on to the builders and architects to pick their brains. A bit like having a What's Your Ailment party and inviting doctors and sick people to attend.
But a virtual party, on the other hand....
A chance to chat about cool projects, interesting building ideas, and maybe some disasters. (Have you seen the Muskoka airport terminal? Did nobody tell them that the window could be centred?)
So I'll start the conversation, but feel free to chime in.
Bring your own beer, though.

Yes, we're still building

Not this year, obviously, but the plans are still being kicked around.

We slowed down considerably after getting some prices in the spring and realizing we couldn't afford to build what we'd been eyeing. Since then, we've been talking, thinking... and learning to use Chief Architect software so we can express our ideas more clearly.

We also continue to read about design, construction, and energy efficiency. It's amazing how quickly some of this stuff is changing. Check out this article on the new energy efficiency code to see how much standards have changed in just a few years.
http://www.greenbuildingadvisor.com/blogs/dept/musings/overview-2012-energy-code
The code hasn't been adopted everywhere (heck, apparently there are still many parts of the US where they don't have any building codes at all!), but where it's adopted it's going to require some significant changes. 75 per cent of lighting must be "high efficacy" (Compact Flourescent or equivalent); all houses must have a blower door test, and in our area must have less than 3 air changes per hour; there would need to be a continuous rigid insulation system outside the building envelope, such as rigid foam on top of a stud wall.) Interesting how a recession combined with high fuel costs is finally driving energy efficient building!
