MADE: A passive solar house of my own design

Rate: 18 Flag

 

In the early '90s it became necessary to build a new house with an office for our business. Having seen a number of homes over the years that inspired me I set about designing a house that would fit a spot on our land that had a view to the east and south making it ideal for a passive solar design.

We had worked with an architect who was a graduate of my college on another house for another location but halfway through the design process we stopped because we finally had access to the top of our hill through a neighboring piece of property. This would allow for more room to build and would permit better solar gain throughout the winter. Having learned a lot from the architect on the previous design I decided to work with a professional engineer who would permit me to design and make the CAD drawings of the house. He would specify the structural parts of the house to ensure that the house met all aspects of the building code.

Looking at the site, a large boulder and the distant view, I started with the corner of the house that would have the living room and worked my way back to the dining room and kitchen. The kitchen had to have a door nearby to bring in the groceries, but should be far enough from the front door to look just right. I went with an open plan for the living room and dining room to maximize being able to look out the windows to the east and south.

For the design I had a few houses in mind that we liked the style of: my grandfather's cedar shingled house in NH, my wife's mother's house in northern CA (see photo below), and a house that was in the distant hill and was owned by the financial columnist Jane Bryant Quinn and her husband. (The mid '80s Quinn house is no longer part of my distant view as it was razed a few years ago in what may be one of Westchester County's most expensive tear downs!)

After months of working on a design, I completed a set of drawings that would allow the surveyors to place stakes at the corners of the house and the excavation could begin. Because one can excavate in our town without a permit, the idea was to excavate down to the ledge rock and then measure the varying heights of the rock and adjust the foundation so no blasting was necessary. The plans were finalized after this and submitted for the building permit.

All CAD work was performed with a program called MacDraft on my old Mac CX. Below is a shot of the screen with a cross-section shown.

 

CAD DRAWING OF HOUSE

 

It took months to build the complicated forms for the concrete foundation and many more months to complete all cement work. From the time of excavation in March, 1991 until the house started to be framed was over a year. I did all of the manual labor myself at night and on weekends. I had to drill over 200 holes in the rock to anchor the house and it is doubtful if an earthquake could ever move the foundation because of this extra work.

The framing took a year and the interior work was an additional year. An electrician and plumber did their related work to house once the roof was on. Because a neighbor had fallen off the roof of his house while checking the shingles I purchased a harness and heavy rope that is the type that tree trimmers use. I never had any problems putting the roof on and at its highest point one part of the roof is nearly three stories high.

One major interior job that I did not perform was the wood floor in the living room and dining room. In about a week a professional did the work that would have taken me over a month!

The septic system was built by the same contractor who had excavated the house and the long trench for the high voltage cable for the house. To keep many trees around the house the septic field is about 200' away and straight down the hill to the southwest.

As designed, we have a decent solar gain in our heating on sunny days in the winter and many fans including one in the attic, plus the many trees close to the house help to keep temperatures tolerable without air conditioning in the summer, although this summer has been about the most uncomfortable since moving in.

This house would not appeal to many people looking for a "great room" or two story entrance hall. It also has no garage and the cars are parked over 100' away which makes for a lot of extra exercise! It is also an "upside down" house since the bedrooms are on the lower level and the main living area is above for the maximum view. These differences from the typical home constructed today could hurt resale in the future if we find ourselves having to move for some reason, but meanwhile I like the house the way it is!

I should add that I am already in the midst of having to repaint the interior and other similar projects on the house. Time, wear and tear, and the weather take their toll on the house.

It was an unforgettable experience to build the house and it is a large scale construction project that I have no plans to repeat!

Very interesting! I'm starting on a small house in Hawai'i later this year that will have both passive and active solar elements, because after all, there's a lot of sun there! :)
David, wow--you can't beat Hawaii for a wonderful climate and plenty of sun. Best of luck on your new house and thanks for the nice comment!
Someday, I hope to undertake something similar . . . I have ideas, and continue researching interesting ways to make use of energy efficient design and materials. I am particularly impressed with the way you anchored the foundation!
Great house, great retreat. Great POST!! Thanks!
Beautiful! Congrats on the EP...you deserve it! xox
Definitely made to fit!
I took a house tour of Jane Bryant Quinn's gorgeous house in North (South?) Salem in the 80s. Can't believe it was torn down!

Fascinating work here.
This is incredible! You will be my muse when I build my own.
Very exciting for me to read this. I've designed my dream house, have translated it into a minor CAD program, and continue to have hopes of building it. It's main features are: Circular and domed with only a few internal walls; layered floors; so many windows that it may as well be called a glass house; completely self-sufficient energy components; a bedroom and a bathroom that translate into an outdoor "English Garden" type of area...so inspiring for me to read about your housebuilding adventure!
Interesting and informative post! It will be a few years before I am ready to build my retirement home but I've already been planning. Especially if I stay in the humid and buggy southeast I have decided on ICF (insulated cement for) to make the place I grow old in truly hose down maintenance easy to keep clean. The ICF forms I've seen result in an R factor insulation-wise of 90, making high ceilings less burdensome to heat and maintain. With slanting greenhouse glass ala A-frame on the sunny side, I want to be able to grow my own table veggies into my 90's indoors. I want my own water source and solar roofing on the topmost parts and even if the world continues down it's current path I should be ok.

Well, I'll never be building a house - but I certainly am impressed with this! great post.
I've done a lot of restoration work on mine. Some major jobs. I wouldn't think about building one from scratch. I salute you.

septic field down hill good.
septic field uphill bad.
I designed and helped build our current house. We used several 'green' methods. We used steel studs in all of the non weight bearing walls and used radiant floor heating with a single high efficiency boiler for both heating and domestic hot water. We situated the house to get the most sun exposure and placed it such that the removal of trees and disruption of the natural drainage of the property was minimal.

Still, it was a bitch to build. The engineering firm that I had to hire to check everything over screwed up a number of things that had to be changed as construction started. Simple things too. Like the number of beams for the floor. We don't have a full basement and they say that 'complicated things'.

So far, the house has been more expensive to heat and cool than we had planned, but not by much. And I get to tell people that I designed this house that they see with their big eyes...

I don't think that I'd want to be as involved if I ever get the chance to build another house. It was hard, but rewarding work. Although subcontractor issues nearly drove us to the nut house. But I wouldn't change a thing...
Fantastic work, great location and nice documentation! Kudos for this accomplishment
Thank you everyone for your great comments on the post!!

I will be back this evening with specific replies to each of your comments.
I enjoyed this look at your passive solar home. We live in a homeowner built house too so every shot of the stages of construction had a familiar ring. A worthy addition to the "made" series.
Further on my comment: We had planned to do more active and passive solar and even wind energy parts of the house but were caught in a real bind.

Our old house didn't sell for over a year and the main contractor (the local municipality requires a 'licensed' contractor for all projects) did not include many parts of the house in the amount they had us submit for the bank loan. Things like counter tops, cabinets, the patios, the driveway... The list just went on and on of things we had to 'pitch in on'. Oh, also no landscaping, even to the point of rough preparation of the grounds after the house was done. We had to cough all of that up. Then, when our house finally sold we took a loss on it. I mean that we sold it for less than the original cost of the house and all of the upgrades we had done over the years were just money poured down a hole. We had put a lot of money into that place over the years. It hurt.

So here we are, several years later contemplating green projects we can do, and most are now out of reach. I'd love to hook the radiant floor heat up to a solar water heater array on the roof but can't afford it. We had thought of doing a wind mill for accessory power too. Alas, yet another project to contemplate IF the economy ever recovers...
Oh, one thing that I found odd was the way the sizes of the rooms changed from point to point.

Like standing in the garage with nothing but stakes for walls, doors, and corners I thought that it was going to be horribly small. Like I worried about it for a while. I actually thought about lengthening it 6 or 8 feet. Then, inside the house, the 'great room' looked galactic in size. It looked to be way more massive than I ever thought it should be. Once framed though, it started to look better. The garage is now a note of envy amongst friends and the 'great room' is a little more Earth sized... I worried over nothing but couldn't get over how strange the proportions seemed to be so off...
congratulations: a great house, and a great personal achievement.

note to other visitors: this wasn't easy, don't try it yourself unless at least half your friends are in the habit of calling you crazy.
Thanks again everybody!! It looks like it will be tomorrow when I respond to your wonderful comments.
This isa very demanding project..Iunderstand the length of time when you are the main source of labor. Beautiful Job! I'm really fascinated with the way the footing conforms to the contorus of the rocks in the ground.
Owl ~ that would be great if you are able to build a house that incorporates your many ideas! Regarding anchoring the house to the rock I should add that 1/2" steel rebar that was 12" long was grouted into each 6" deep hole. The holes were 1" in diameter. Thank you!

Kit ~ thanks for the nice compliment on the house, retreat and post!

Robin ~ thank you very much and I appreciate the kind words!

Dave ~ definitely a custom type of job for a tight spot amongst the rocks! Thanks!

Patrick ~ thank you! I appreciate the positive feedback!

Lea ~ it must have been a real treat to see Jane Bryant Quinn's house. From the exterior and the newspaper article about it in the '80s I could tell that she had a very attractive and unique home there with one of the best views in northern Westchester. There was another expensive tear down of an '80s house a few miles away in North Salem. That house was featured in a mid '80s edition of Architectural Digest and if I find my copy I will post about it because the house belonged to the father of a college classmate and the person who had the house removed is an international celebrity. Thanks for you nice comment!

Leah ~ thanks very much and I am available to be your muse when you build!

Gailrae ~ wow! . . . it sounds like you have a spectacular house already designed! I look forward to your building it and showing photos in the future! Thanks for your story and nice comment!

Fred ~ an R-value for the ICF is amazing when you consider how much lower the R-value is for most homes! A greenhouse along one wall would be a great addition for not only the vegetables you could grow, but for the interesting aesthetic and light additions to your design. Thanks for your interesting story and comment.

Marlene ~ just in case you find that you are building a house in the future please don't hesitate to ask me some questions! I appreciate your nice thoughts on the house and post!

Wschanz ~ I have enjoyed working on existing structures a lot and wasn't sure if I would ever build a house from scratch. I love the charm of older houses and barns and it can be difficult to make a new house that has the same feel. I agree with you on the septic field being best down the hill! Even though there are elaborate pumps to handle a field at a higher location than the house it is another thing that can break and when there is no power there is no pumping unless one has a generator or other means of power like heavy duty batteries. Thanks for the great comment!

Gonzoid ~ I looked into steel studs for our house but felt it would take me forever to deal with them because so many lengths were involved. Also the majority of the walls here are about 8" thick. I have 2x6 for the outer wall and the inner wall is 2'3s that are staggered so there is less heat loss through the studs. It was extra work but it added a lot to R value of the walls.

Nice to read that you have radiant heating! I could still go that route in the future for parts of this house because much of the floor joists are accessible except for the floor joists of the living room and dining room--those are impossible to add radiant floor heating to unless I rip out the sheetrock underneath. A neighbor who has a lot of cathedral ceilings went the radiant heating route and it works for them quite wekk so far.

I was sorry to read how the many enhancements you added to your house were never realized as a profit when it was sold. I can feel how frustrating that must have been! I have heard many stories of problems with contractors and sub contractors! I had very few--the plumber, the electrician, the excavator and septic field builder, the kitchen cabinet builder, and the fellow who put in the wood floor. They were all smart, skilled and I had zero issues with any of them!

I can appreciate the way the sizes of the rooms changed along the way for you when you were building. I noticed when I was putting up the sheetrock how that also changed the scale of the interior. I can remember being surprised at how high the house was going to be in relation the site since I was trying to keep the house from not standing out when seen from a distance. The choice of natural wood for the trim and shingles helped to blend the structure into the surrounding woods.

Thank you for your many interesting stories about your own house--fascinating to read! I hope you post about it with photos!

Nikki ~ thanks for the wonderful thoughts on the work, site, photos and finished house! I am glad I took a lot of photos along the way--there are many, many more than I show here but I had to keep the post from getting too wieldy!

Stacey ~ I have enjoyed your unique posts on your many house-related owner-built projects! It's always fun to compare notes about how each house was built and unique situations that had to dealt with. Thank you for your wonderful comment!

Al ~ thanks very much! I remember some friends saying that friends of theirs spent 8 years building their house and despite hearing this somewhat discouraging story early on when I was just starting the house, I continued with the project.

Gary ~ I appreciate your nice thoughts on the project! With blasting often the option for houses in an area where there is a lot of ledge I felt this was more of a unique and attractive approach rather than blasting away all of the interesting rocks that run right through the basement. I will add here that to make the forms follow the contours of the rock I had to run a pencil with a piece of wood along the rock and scribe the 1/2" plywood and then cut along the pencil line with a hand-held jig saw.
Okay, so you're kind of amazing:) rated.
That is one heck of a 'made' product! Three years is a lot of work and it looks like you are enjoying the fruits of that. Very interesting designanator!
