Slightly Bigger
Too Big?
Last night I called up the local building supply company to see what lumber costs might be for the roof framing of the building pictured here. A very rough guess brought me to about $10,000. This started me thinking that this plan is too ambitious. Yes, we all would like a nice living room, lots of storage and a comfy kitchen, but I'm starting to think it's too big for our budget.
So, I cut down the plan too see how big our minimum requirements might be. They're pictured here in a plan that provides only a kitchen, bath and shower, plus a little storage space. This building would quite a bit less than the above, the roof framing being about $3000. But, I question whether this smaller kitchen would serve the camp needs, especially if we're considering renting the place out to others. It provides no place to go when it's cold.

Hipster
Getting down to the wire! Annual meeting is in two days.
I'm focusing on the roof pictured here, a "dutch hip" or "hip-gable". I like the way it shelters the entire building, inside and outside porches under a single shape, give opportunity for ventilation in the little gables, possible place for loft sleeping above the porch, and it looks interesting from the meadow, being a little more complicated than a simple gable butt in an elegant way.
Today I will be building a presentation model. Jay Schuster has agreed to bring a data projector to the meeting so I can walk everyone through the design in real time.

Land Visit
Gabriel and I visited the land today and met up with several other faeries up for the work weekend, Peat, Bambi and Jim pictured. I was able to take some panoramic images and verify that the land more or less conforms to the computer generated model. Several of us took a walk up to the site and discussed the clearing plan, the privy location, septic system location, orientation of the bath house and the kitchen building, access to the buildings and the distances between the buildings. We happened to arrive just about noon so due south was obvious (the sun is always due south at noon) and that helped with visualizing the building orientations. The site feels a lot smaller to me than it does in the computer simulation.
This week I will be spending nearly all my time working on the design getting it to a presentable state for the annual meeting in Burlington next weekend.

Foundations
Pier
This is a common rural type of foundation made up of concrete piers set on footings about six feet below grade. Little earth work is required, little concrete and it can even be done by hand if there's enough labor available. The underside of the building floats above grade creating a space under the building. This has the disadvantage that air moves under the building making floors cold. Animals and other critters can make that space home. If building with straw bale this technique can be expensive because straw bale weighs alot and the beams you have to use to support it might cost more than the difference in the cost of a slab foundation.
Basement
This is the most common type of foundation in New England because it provides excellent frost protection and a place to put all your junk. Deep footing walls create a protected air space under the building that stays about ground temperature if not heated or cooled. The space provides a place for mechanicals and easy underfloor access. This kind of foundation uses a lot of concrete and is usually installed by a professional with formwork and is often one of the more expensive parts of a building.Frost Protected Shallow Foundation
This type of slab foundation, pictured right, was championed by Frank Lloyd Wright and has been approved for use all over the United States and Canada. It's been proven to perform as well as a basement foundation in frost protection but uses a fraction of the concrete and labor. It does usually require the use of foam insulation which I'm not sure is nasty to fabricate, but seems like it probably is. A large skirt of this insulation spreads out from the building, more in the corners, to keep frost from getting under the building and heaving it. Temperature records of FPSFs show that even in the harshest of climates the temperature under the slab remains above freezing. A disadvantage of a large mass foundation like this is that it takes a long time to change its temperature, which could be an issue for Destiny since in October, for instance, the slab would not warm up much at all during the course of the gathering. Passive solar design might be able to help with this and keep the slab warmed enough even in winter months.
Straw Bale
One of the more radical foundations I uncovered is the straw bale foundation. A two inch layer of concrete is poured over a stone bed, straw bales are laid with spaces between them, then another layer of concrete is poured over the bails, filling the spaces between which support the floor above. The straw provides insulation and the small concrete infil columns provide structural support. A firm in Quebec, ArchiBio, pioneered these and several are in good condition today, although in some the straw has rotted, which doesn't structurally affect the slab which is entirely supported by the concrete between the bails. This kind of foundation seems a little iffy to me, but I'm going to look into it more.Concrete
There's no doubt that concrete is very useful material. But there are less energy intensive alternatives. For instance, plain old earth. Earthen floors are common in less industrialized countries and from what I can gather can be just as tough as a concrete floor. An earthen floor is made up of clay, sand and some kind of binder, often straw. This is mixed into a paste not unlike concrete, poured like concrete, and let to dry. An oil is used to seal it. Earthen floors have been successfully employed in retail spaces with heavy traffic.
Green Roof
What is a green roof? It's essentially a roof with several inches of light weight growing medium in which hardy plants live providing protection to the roof and insulation from temperature swings. The roof structure has to be stronger to support the additional weight, but not so much that it would increase the cost of the structure significantly. A green roof captures a lot of the moisture that falls on it, reducing the runoff from the roof which help keep the walls of the building dry. This is really important in straw bale construction. Some cities, mostly in Germany and Japan, are incenting green roof construction because it so dramatically reduces runoff which has become a serious issue. A green roof would also look pretty interesting. Some people use goats to keep it tidy.
Staw Bale
I feel like it's a good option for Destiny primarily because it takes little skill to put up which means more people can participate meaningfully in the construction. It also appeals to my sense of adventure and I would really love to learn how to put a straw bale building together. It's also radical, bucking the use of mainstream materials in favor of simpler and very sustainable technology.
I have faith that it would work. A book published by Chelsea Green called Serious Straw Bale describes projects mostly in Quebec, a climate much like ours, actually harsher. Fire is a big concern of many, but straw bale being completely encased in mud, lime or concrete, has high fire resistance, and it can be coated with boric acid before mudding to further retard combustibility.
Budget
Even so, this is an incredibly tight budget that will require using as much inexpensive material as possible. Using the wood from our land may help. Using recycled materials, things we scrounge at dumps, things that Keisha and I have stored over the years, and perhaps using straw bales for the walls may also help. Typical new construction today ranges from around $80/sf to over $200/sf. If we build a 1300 sf kitchen for $33,000 that's about $25/sf. I think this is doable. We just have to be very careful and not too picky about what we can get.
Inside
First, an open area that can be used for dining, circling or anything else. It would have tables, chairs, perhaps some built in benches along windows, some storage and probably a woodstove or fireplace.
Second, the kitchen area, more or less in the middle of the building, to prepare food for gatherings. The kitchen will have a six burner stove, an oven or two, a three-bay sink for dishwashing, and lots of counter and storage space.
Third, at the other end will be a bathroom, shower and mechanical room, and probably some more storage for the kitchen. The mechanical room will house a water storage and pressurization system, the solar power works and the water heating system.

Accidents & Unions
So, here's a basic pitched roof building...
...and here's a glass house.
Now glue them together and, viola, a nice screen porch wrapping the traditional building. Sure there are some wacky things that happen, but those can be worked with. The essential idea of intersection a rectangular screen porch with a slightly bent pitched roof building seems very pleasing to me and provides an essential need for the design: making a space for people to hang out when it's buggy.

Massings
TRADITIONAL This one is a traditional pitched roof, about 45 degree angle, which would be metal most likely. The building is kinked slightly to embrace the space on the south side of the building (what we're looking at). This would be very easy to build since almost every building in New England looks like this. One nice feature of this kind of design is the large roof area that's visible, which is missing in some of the designs below. You can check out how not seeing the roof changes the feeling of a building.
GLASS Here's kind of a joke, but interesting. This is a glass house design with a flat roof. Contrast this with the prior model. A very different feeling. I don't think this would be practical but it's kind of the other end of the extreme from a standard pitched roof with solid walls.
CRUSH This was the first massing experiment I did. I was thinking about a green roof and what kind of surface would be appropriate for that. I thought that perhaps a multi-pitched roof would look kind of cool mimicking the terrain. I still think it would look pretty cool, but my feeling is all the angularity actually disguises the building. Even in this simplified model the complexity makes the building a lot less clear. It would be a lot harder to build too.
SLANT Here's the same shape building as the pitched roof but with a big slanty roof. I like the way this design counterpoints the downward slope of the land with a rising roof. I think I'll play with this one a bit more, trying to angle the roof so that it's more visible from the circle.
CUBES Some cubes to mimic the bathhouse, which is also a cube of sorts with a pyramid roof. The idea here was to have the kitchen and dining areas each in a separate space. It looks a little too much like a commercial mall building for my taste, but I think that could be dealt with. My feeling is that the kitchen and dining space should be one however, so that the cooks don't cut off from social activities. More on this later.
Comments welcome.
Birdseye
I'm jumping the gun a bit with this post, but I will get to details in a bit. The bathhouse uses the existing kitchen structure built by John Tidd as the central dressing area. The kitchen in this image is a vanilla pitched roof structure, but it doesn't look too bad.
Now that I have this 3D model I try out all kinds of different models out on it, checking out the sun, time of year, views. The only problem is that the leaves don't fall off the trees in winter.

The New York meeting didn't really consent to a particular plan, but encouraged the development of ideas in 2 and 3. The kitchen in 3 was liked for its embrace and the location of the bathhouse in 2 was liked.
After the New York meeting I took a break from design, which didn't pick up again until February 2005.
The Site
The Design Comet, a small committee, formed last summer to move the design process forward with the hopes of starting construction this coming summer, 2005. The first things the comet did was to take a look at what had been done. Many things had been decided, including well location, kitchen and bathhouse locations and the construction of a road to the well site. After collecting a lot of information about our water system, sun patterns, sound and neighbors, the Design Comet decided to reconsider the site plan and hold off on any further construction until this spring.
To begin with, we (the comet) began looking at the overall site, the allowed development area, and the clearing that had been done to date, with an eye toward siting the building to take advantage of sun, slope and any aesthetic features on the land.
This sun study shows how sun plays on the land throughout the year. This study showed that because of tree heights that any buildings placed along the western side of the meadow or any cleared land would be in shadow a good part of the day, even in mid-summer. This suggested moving the buildings to the eastern side of the land where they could receive full sun most of the day. Three schemes were developed start the design process.
The first shows the site as it is, with nothing done to it. A meadow has been cleared and a road cut in. There are no buildings on the site. This do nothing option was really not an option since our permit to be on the land requires us to make certain improvements, such as the water system.
The second shows two acres cleared and the buildings as permitted. The two buildings (brown squares) shown are the permitted kitchen and bathhouse. The kitchen was permitted to be 576 square feet and the bathhouse 400 square feet.
The third plan shows five acres cleared and the buildings relocated to above the road and to the east of the meadow. This arrangement came about as a result of discussions on the land, looking at sight lines, sun, accessibility and construction issues and was ultimately chosen as the route to pursue for further development.
Welcome
I'm hoping this blog will serve to fill in the gaps between meetings, allow people who haven't been to the meetings to peek and comment on the design process. I will post drawings with commentary and anyone can put in their two cents using the comment mechanism. I will check the blog regularly for comments, and respond if it seems appropriate. After it's all done we'll have a nice record of the process.
