8 Tips for Siting Your Natural Home


Whole Trees Architecture and Construction

Before you even start thinking about the specific design of your building, you can have a huge impact on its comfort and cost by choosing the site wisely.  Issues of solar gain, prevailing winds, and drainage are key, as well as more personal considerations like your favorite view.  Some of these issues can be resolved with a little websurfing and a good topographic map or aerial photo of your land (check with your local county surveyors).  No matter what you find online, though, you will need to go spend some serious time on your property, wandering the site and opening your senses.  Remember, finding the perfect building site is more art than science.  Answer these questions now rather than after you move into your new green home.

1. MACROCLIMATE: How big is your sweater collection?.

The internet is your best bet for this material.   Do you need AC to survive the summer humidity (note that there are a number of natural building solutions for dry heat that don’t require any extra energy)?  How much heat will your house need in January ?  Fix this data firmly in your mind and carry it with you as you move forward into design.

2. MICROCLIMATE: Your own little world.

Aspect: Aim south.  If you are building on any sort of slope try to make sure it faces the south.  Of course you want to take advantage of passive solar in your design and possibly  incorporate  solar hot water or even PV panels, but don’t forget the heat in the ground itself; a south facing slope gets the most perpendicular winter rays – which translates to the most warmth – which you can translate to your heating load in the winter. 

Air Movement: Watch out for Frost pockets.   In many ways cool air flows like water, rolling down hill, collecting in valley “streams” and then pooling up against obstructions (like your house), where it can create a “frost pocket.”  This will kill your landscaping and up your heating load.

3. SLOPE:  Be gentle on yourself.site plan5.19.09.indd

A gentle slope is ideal.   A very steep slope can create more trouble than its worth in excavation costs and complications, but the level parts of your property are often best used for other things like garden space and out door activity areas.  Meanwhile your house can take advantage of an angle. 

Waste: An indelicate subject – its costly and problematic to pump sewage uphill.  And the image of a pump stalled by power outage or mechanical failure is not pretty. Just one more reason to look for a hill side site – and plan your drain field down hill.

4. IMPACT: Minimize it.

Avoid blasting through bedrock as this is both expensive and environmentally unsound.  Conversely if the soil on your building site is really great, consider moving the house  and making that place into a garden.  At the very least, move good growing soil mindfully and make use of it somewhere else after construction.  And please oh please oh please don’t buy up and build on prime farm land, either individually or as part of a subdivision.

In the Midwest you’ll want sun in the winter and shade in the summer.  (The design of the building will address this, of course, but if your site works with you rather than against you, so much the better.)  Make sure that if there are any trees between your site and the sun, they are deciduous and will lose their leaves in winter.  This can be the best of both worlds, offering cooling shade in the hot months and accommodatingly removing it just when you want to start collecting that solar energy in the fall.  Consult a sunpath diagram to see how the sun will move through the day and year in your location.

6. DISASTER: An ounce of prevention …

Say it with me: Don’t build in a flood plain.   Don’t build in a flood plain.   Don’t build in a flood plain (one more good reason to seek out a gentle slope).  Ask the old timers, check the public records, consult the FEMA maps and … don’t build in a flood plain.  In this age of extreme weather events (global warming, anyone) don’t tempt fate.  100 and even 500 year flood plains are being re-drawn in the last decade.  This goes for the edges of cliffs in ‘quake country and for ridgetops in tornado alley.  If you are in an area prone to wildfire, consider how roads, streams and open areas can be used as fire breaks to protect your house.  Or, even better,  don’t build in fire country.

7. GETTING THERE: Do you really want to focus on the journey?

This issue works at several scales.  Within your site, the further your house is from the lot line, and the more circuitous your route from point A to point B, the more land you must disturb and the more costly your driveway will be to build … and to maintain.  Likewise, the farther you are from civilization, from groceries, from work, from family and friends, the more fossil fuel you’ll burn getting there and back.  Weigh your desire to get away from it all against your wish to live like a hermit.

8. BEING THERE: Use your senses.

Last but by no means least, experience the place.  Nothing but time will do this for you.  Stand in the building site.  What do you see, smell, feel and hear?  (Don’t taste anything unless you’re pretty confident in your back country skills.) Do this at multiple times of day and through a year or more if possible.  What are your favorite views?  Can you hear trucks on the highway or see your neighbor’s blinding security light at 3 AM?  Think about how moving your building site around may shield you from the bad and enhance the good.

9. WHAT DO YOU THINK? If you have encountered another issue that impacts your own green site,  shoot me a comment.

Note: As I continue to talk about the process of designing a natural home for Denise and Doug I will primarily be addressing the climate and site and design issues of the upper Midwest.  There are excellent sources of planning and design materials for every region in the country available in book form and on the internet.  I have (for the most part) focused on the design principals and techniques best suited to this climate.  The importance of a place-based design culture cannot be over estimated.
