3 - The Housing Options We Considered

I guess by simply looking up at the title and explanation of this blog, there is no real mystery shrouding the outcome of the following deliberations. Nevertheless, let’s press on in the spirit to which we have become accustomed.

Own Design and Owner Build
The first option we considered was one that I had always assumed would be the only way to go when it came to building a house for the land here. It was, of course, to design our own house featuring all the little quirks we desire along with all the energy saving features we had learnt about over the years. It would be unique. We would gather recycled materials and do a lot of the building works ourselves.

So what happened with this idea? A few things did, none of which were more persuasive than the other, just awfully influential en masse. Firstly there didn’t seem to be that much in the way of savings to be had. Having a unique one off design can be expensive. Not sure how expensive but I was told it was substantial. Then there are still the services such as plumbing and electricity to be completed by other people. Of course the plan is that these costs could be offset by doing some building work ourselves. This got me thinking. Building one’s own house is a lovely thing to do and something I greatly admire for many reasons, however, I do not have the interest, inclination, patience, time or skill to do it. A large adventurous part of me wishes I did, a smaller practical part knows I’d struggle, and a tiny self care part, thinking of the longevity of my fingers, limbs and relationship, strictly forbids it.

Building a house and learning as you go takes a lot of time. I couldn’t really take this time out of a paying day job because at the moment we need the money. Doing bits and pieces here and there on weekends and the like would stretch the whole thing out beyond any realm of acceptability. We did not want the building of the house to become our entire lives, having to constantly field questions on its progress from everyone we know for the next 5 years. We have a child to raise, trees to plant and food to grow.

Kit Homes
We spent many months looking into kit homes. At first glance, from a distance, we were wooed by the prices and seduced by the promise of time savings. When we got closer, warts and alls started emerging. Here is a collection of what we discovered.

SALA Homes
This was the first company we took a passing interest in about two years ago. They make 5 star energy rating houses which incorporate a number of nifty features and building materials that reduce the house's overall impact on the planet. After a brief look at their designs we ignorantly deduced that their houses were a bit too modest for our needs. We also grossly underestimated the costs involved in actually building the house, assuming that the overall finished house price would not be that much more than the quoted material price for the kit. We thought we could easily afford much more than what they had on offer, how much more was a figure we didn’t know at that stage because we had not done any sums. Anyway, for the next year or so we shelved the house plans to make mental room for other things. After this time we returned to the SALA idea. They had more designs available and after sitting down with a pencil we mapped out how one would work for our specific site. We liked the four bedroom SALA Green and were becoming increasingly excited about it. The costs seemed reasonable on paper, $165000 for the kit, remember though dear reader that we had not really ironed out the detail in our budget.
We went on a tour of an estate that has some SALA display homes. This was very encouraging, we arranged a meeting with the SALA team in Brisbane and talked over the changes we had in mind for their plan. They were very easy to work with and open to new ideas and suggestions. They even encourage changes as long as they do not detract from the overall efficiency of the house. Everything seemed right. But it wasn’t. Someone mentioned a safe guesstimate monetary figure when working out the cost of the fully built house – “add about 80% of the kit materials figure to that very figure”. The world spun around me. Further spoken words after those corkers blurred together into a long continual throat song sounding note. I was in a brief shock. I felt like a fraud, sat there talking turkey with people who thought I knew more about turkeys, like how many hooves they have on the ends of their opposable tails. Arrghhhh. We politely wrapped things up, threw on some niceties, and exited the office.

Following this revelation we were quite disappointed. It was made worse by the fact that we first saw the SALA option as a cheap one. In fairness to SALA their safe percentage figure included the complete building of the house and further allocation for driveways, water tanks, extra solar panels, on site sewage management and the like. We would need all these things, it’s just we wanted to do it for a lot cheaper than $300 000 – at that stage we knew this was way over even our fantasy budget figure. Despite this setback we were so impressed with the SALA staff we went home and worked on working with another cheaper, smaller, simpler plan, the 4 bedroom SMART. Here is a blog
, documenting the building of a modified SALA Green House.

Other Kits
During this time we also looked at a range of other kit homes for comparison hoping that something cheaper would emerge. We wanted to find out if the SALA’s vented wall system, high pitched roofs and other passive climate control features were worth the extra cost. Now of course this is hard to gauge when you’re talking houses, they are not available for test lives on your specific site. I guess we started trying to make educated assumptions about the significance such features would have for us and if their impact would be substantially noticed. Additionally though, SALA does use sustainable materials, where ever possible. They also come with very functional louver windows, wooden French doors high ceilings and 12mm Ecoply lined walls as standard, turns out they share our distaste for plasterboard. All these are nice features and things we would perhaps try and incorporate in other kit homes.

The first place we enquired at was
Valley Kit Homes . They were situated about an hour’s drive from us so after looking into a few of their plans via their website we made an appointment to see them and ask questions. We arrived to meet our host, and after briefly looking around the display stage set style interior layout boasting the company’s finest in fittings, we reclined across from a desk cluttered in photos of houses and grandchildren. Our host seemed nice enough to begin with and listened with a pained smile as we fumbled through the delivery of an introduction to our situation and some of our preferences for the designs. She responded obligingly showing us some real life pictures of finished houses. These were not to our taste and as we started to unpack our questions of alterations to the designs and incorporation of things like high ceilings and wooden wall linings and window frames, her answers became increasingly shorter in both length and tone. It is as if the more questions we asked the more she did not want to secure our business. We did get out of her that most of the things we enquired about were doable but were “very expensive”. She did not give the impression that she represented a company that was progressive in its concern for the preservation of the natural environment, good style, flexibility or plain common courtesy. Maybe she has come across our flakey type before who ask lots of questions and don’t come back. Maybe it is her job to filter out our kind. Maybe she personally loves all the things we wanted to change and was deeply offended by our insensitive remarks. Or maybe she was keen on nipping down to the shops in her lunch break to return a pair of slacks she was going to wear to a friend’s 60th that weekend. Who knows? On the way out we were guided via another display, a wall of external cladding options that were mostly fake wood grained imprinted Hardiplank which I’m sure it is not without its function and charm in certain situations, hopefully though, not ours. We did not speak of Valley Kit Homes again.

Another nearly local company is Affordable Steel Kit Homes
. They pride themselves on their steel, easy to put together, framed houses. Their designs seemed to hold more potential for us than Valley Kit Homes did. We were sent their information pack, complete with a rather odd promotional DVD containing a collection of their recent appearances on various home shows that we had never heard of. This is not saying much though as we are not ones to watch such programs. I went along one afternoon to their offices and chatted with one of their youthful polo-shirted team members who had a tendency to smile smugly after each of his confident assertions. He was a nice enough chap, though naïve to some of the finer concerns I had about things like passive solar design and the inclusion of recycled materials. I came away from the meeting with a wary feeling. Not something you want from such encounters. The one thing I did take on board from the meeting with ASK was that it prompted me to do an online Owner Builder Course through Access Building Education. We figured it couldn’t hurt to have it ready incase we decide to go ahead with the kit option. Even if we didn’t do any building then at least we could save money on overseeing the project. It cost $155 and was rather informative.

When comparing all three meetings, our experience with the SALA people won hands down in making us feel understood in our desire to feel understood regarding the elements we feel are important to include in our future house. They were literally unreal. This fact, coupled with their overall philosophy and inclusions such as solar panels prompted us to decided that we would go with SALA after slightly rearranging the internal layout of their 4 bedroom SMART House. We would make it three bedrooms and with a larger living area.

We did look at a lot of Kit Home companies during this time and followed some up with detailed enquiries. This list includes some of them.

Agnes Water Kit Homes
Classic Queenslanders
EHabitat
Gateway Manufacture
Ecohut

Smart Shax
Sustainable


As we started to crunch the numbers on the SALA home, we became increasingly concerned about the costs. Because of this we kept looking around.


Project Homes
Our neighbour had a project home built a few years ago. It seemed rather cheap for what she got and, due to its orientation, was rather cool in summer and warm in winter. We could not help then to at least investigate the possibility of building one here. We found a number of companies with a number of designs. This is as far as we got. We shook ourselves out of what was an irrational moment of poor judgment. Project homes represent everything we do not want in a house or in our lives. We actually felt rather ashamed of even considering such a thing, however fleeting. The biggest issue for us is the companies’ seemingly complete lack of concern for sustainability. They appear to build these houses unecessarily large these days, with air conditioning in mind, featuring things like rooms tucked away without cross air flow, small or no eaves and large windows all the way round the house.

We’ve always only wanted a small house. Anything too big is rather pointless and somewhat embarrassing, especially considering that we moved out here to be ‘out’ here. Not inside all the time. Media rooms, powder rooms, activity rooms, games rooms, and the myriad of other useless extra rooms they often include in such houses hold no appeal for us whatsoever. I read somewhere once that paying off big houses is like renting out a heap of rooms in a hotel everyday and not using them. It is sheer waste poorly disguised as decadence. We could not live with ourselves living in a place like that. For us these kinds of project homes serve as monuments to everything that is environmentally and morally wrong with the planet, from the materials that make them to the energy they consume after they're built.


Relocatable Homes
My partner had always wanted to move an old house onto our block. It made sense. Old Queenslanders have all the features that we wanted in a house and we have enjoyed renting them for the last ten years or so. The only thing though was that we had heard that they can be quite expensive once they're moved and restored. So it is with some trepadation that we started searching house removal sales companies' collection of current stock. We found
Drake Removal Homes, south of Brisbane, and decided to go along to their yard to see some houses in the flesh, errr... wood. We met one of the salesmen and as we left the office to walk around the houses, he reminded us to use our imagination. We looked at few places that we had already seen photos of on the website. They were different up close. They required a lot of "imagination", only thing is imagination costs money in this context. The old wooden houses we looked at would require major work to replace decking, roofing and all sorts of other odd bits and pieces. We discussed the removal process with the salesman on the way out and left him our details for email updates of new stock. We would need a house that did not require much work for this option to be viable for us.

1 - The Back Story

Since purchasing a 15 acre block of land in the beautiful Tweed Valley in northern New South Wales (Australia) some five and half years ago my mind has seemed to constantly be entertaining thoughts of what type of house to build here. No “Owner Builder’ magazine crossing my path was left unopened, no related website was left unclicked, no picture of anything habitat design related was left unscrutinised and no new approach to ‘green housing’ was left unconsidered. Two years ago my partner and I moved onto the block and into the barn shaped tin shed that was already here. As we busied ourselves with making the shed livable, the pressure eased on the house front. That is until our daughter was born ten months ago. Suddenly we realised that it would be nice to have a house before she was walking about.

Our housing requirements are humble and reflect the very reason we moved from the city to take up residence here. We wanted the house to be as sustainable as possible and so it would need to incorporate passive solar design and solar power, and of course, by virtue of our lack of town water, on site rain water collection and waste management. We hate the idea of having a house that requires air conditioning so ours won’t. We will utilise the cooling breezes with properly placed windows and minimise the heating effects of the sun by house orientation, insulation and eaves.

So as one can see the basic plans were simple. However, due to the fact that my partner and I have strong opinions on what we like in houses, other preferences would need to be factored into this basic outline. These come in varying degrees of ‘must have’ and could be reluctantly compromised upon if pushed. Because they each require an explanation, they have one below.


The site chosen for the house

High Ceilings
My partner and I spent most of our twenties not knowing of each other. We lived separately with ex-loves or in share house arrangements in a collection of rented inner city Brisbane houses. Whether they were workers’ cottages or larger Queenslanders they all had one rather impressionable feature in common – high ceilings. Being in a room whose ceiling height is often double your own is quite a nice thing and not easily forgotten, especially when you are considering committing yourself to purchasing a house that will take you a large portion of your working life to pay for. You kind of want ‘nice things’ in it. Of course there is the added benefit of high ceilings making the house cooler so their inclusion in any building project for us is almost a given.

No Plasterboard Internal Linings
I really do not like plasterboard internal wall linings. As children we were warned against marking their clinical finish when our lives got too close. “Mind the wall you’ll damage it/mark it/ruin the entire house’s resale value” – as if it were some canary in a cage gauging the well maintained history of a house to a would be buyer. I have always thought it odd that the internal walls of a house needed to be taken care of in this way. Life is way too short to curb exaggerated limb movements, contain inquisitive grubby hands or to always keep outdoor sports strictly outdoors. Houses are for living not minding. Bear in mind that perhaps my particular experiences may not be that common, however, for me they formed a strong foundation with which further plasterboard negatives could rest.

Again, like high ceilings, once an alternative to plasterboard was experienced my aversion grew. Older wooden houses sporting V J tongue and groove lined walls provided a secure comforting back drop to the dizzying jumble that was my twenties. Walls and ceilings that you could put nails and screws in held up all sorts of heavy junk. Disco balls, push bikes, retro pod like recliners, complex clothes racks, big stereo speakers and countless chunky framed pictures were all supported by these wonderful neat planks of wood. Their durability easily absorbed many an overbalanced house party reveler, bouncing them back into the throws of the dance (
loungeroom) floor within the blink of an eye.

Wooden lined walls have a certain substance and feel to them. There is a real richness and depth to their presence. Plasterboard lining gives me the complete opposite sensation – one of temporary brittleness, sort of like living in a chalk cell or a flimsy stage set.

Plasterboard is used so extensively because it is cheap, money wise, to produce. However, I have recently discovered that this production carries high inherent energy costs making it not a very sustainable option for the discerning home builder.


Wooden Windows
Another important consideration in the house is window frames. Not a lot of options here in the way of materials used but fortunately we love wooden framed windows. We do not like aluminum framed windows. I have never understood their widespread inclusion in brick veneer houses when they look so bad with brick. Bricks give a solid earthy feel to a house, while aluminum windows detract from this effect with a look of flimsy fabrication. For me wooden framed windows suit so many applications in building. Their styles are endless.

The trouble can be that they are expensive. To overcome this we hope to include some recycled wooden windows with the added benefit of them often being more interesting.


Wooden Floors
People buy carpet. They carefully select the colour and texture they want, running their hands over the sample piece, perhaps even rubbing their cheek against its softness. They then pay a substantial amount of money for it, take it home, put it on the floor – the one place where it is next to impossible to take care of, and then walk on it. An endless cycle of precautions, cleaning, fussing, cursing and resenting seemingly trivial actions of family members begins. An un-winnable war against gravity is waged. I can’t see why people bother when there are other options?

Hard surfaced floor coverings are the only ones worth considering for me. Wood looks the best. So wood it is. Slate comes in a very close second and should the house be built on a concrete slab, would probably be the pick.

"I'm gonna surround myself in wood! Wood Jerry! Wood!" (Kramer)

So there it is, a few basic requirements complimented by a few taste requirements. Meeting all these should not be too hard…should it? Next step is to nut out a budget, decide on a style and building technique, consider size requirements and think about a floor plan.
