Designing a Natural Pool with additional fish habitat area for the Sustainable Hemp Home Series.
Since the Hemp Home Designs are all about Sustainability. Why wouldn’t the pool be as well and while we are at building a natural pool we might as well incorporate a fish habitat into the natural pool design. This will allow the pool to serve as a food source in addition to the entertainment value.
Reserving at least 50 percent of your pool’s surface area for shallow plants, either at one end or in a ring around the sides, eliminates the need for chlorine and expensive filters and pumps. You’ll want to separate the swimming area of your pool and the filtration area, or plant zone (see the illustration in the image gallery).
The water needs to circulate continuously for the plants’ roots to cleanse the pool. You also may need to aerate the water so the water organisms’ oxygen needs are met.
Without adequate oxygen, your pool could become stagnant, harboring odoriferous anaerobic bacteria.
Besides cleaning the water and making your pool beautiful to behold, the shallow plant zone warms the water quickly and provides habitat for frogs and many invertebrates. They’ll appreciate the shallow water for breeding grounds and repay the favor by eating mosquito larvae.
A rim within an inch of the water’s surface keeps plants in their place but allows water from the swimming area to move to the plant zone for filtering, As water passes through the fibrous root structure of the plants, bacteria concentrated on the plants’ roots act as a biological filter, removing contaminants and excess nutrients in the water. Decomposer organisms, also found in the plants’ root zones, consume the bacteria, effectively eliminating underwater waste buildup.

Builders have been building Homes and Commercial Buildings using this design in Europe for many years now. With the legalization of Industrial Hemp in the USA. Now Americans can adopt this Sustainable Building practice into our designs to create homes that can grow and be built in 2 years.
In this example of Hemp Building I’ve eliminated much of the excess lumber that is not needed in the build because of the Post Frame Structure. When the Natural Lime and Hemp Fibers are mixed together it creates a concrete like material that is also high in insulation value- you get the best of both worlds:
A strong and durable Building that is also energy efficient that can withstand the abuse from the elements.
This Natural product that can also be grown most anywhere in the USA.
Thank you for checking out the CAD designs on the use of Industrial Hemp for creating an Energy Efficient Home.
If I can assist you in your quest to design or build using this type of construction technique utilizing hemp or other natural green building products drop me a line and let me know. Scotty

Replied to My Question on Hemp Building:
I’m designing a Hempcrete home and have been looking into a Catalan Style Spanish Roof for a roof system that does not require lumber. Do you think a hempcrete product would replace the concrete the spanish masons use? I’ve started a series of articles on the planned build at: Q and A Greg Flavall Hemp Technologies
Mr. Greg Flavall Co-Founder / Technical Director Hemp-Technologies Answered:
“”having looked at your website and design I’m intrigued. Although we have not done this style of roof I do not see what lime could not do the same as cement in this application- if it were sealed correctly. Typically we are using Hemp/Lime for walls which is covered with 15-20mm of lime plaster for weather protection on a vertical plane. We install hemp/lime under the roof where it is protected as insulation and in the floor (above grade only) where it can breathe.””
Why would you not consider a green roof cover in this style, much like the Adnams Brewery project in UK completed in 2008? Seems to me a better use of area.
Scotty added from Google Search for Adnams Brewery:
In my quest to promote affordable sustainable buildings has lead me to discover a new building product that provides high R-value for energy efficiency and has the strength of concrete. Hempcrete the new miracle building material! Since this will be my retirement home, I realize that to make my limited budget go as far as possible I will need to be:
Net Zero in Energy Consumption and Energy Production and at the same time being
affordable to build on a limited budget.
Most everyone is aware that Living Trees are needed in removing the Carbon Dioxide from the Air and if you have been to the local lumber yard lately the prices of lumber needed to build a traditional stick built home can be astronomical for the average budget and until insulation is added to the structure they are not energy efficient.
This Hemp Home design I’m working with eliminates a great percentage of Lumber needed in the building process and provides the insulation that will make heating and cooling this home easy and will be affordable! This is the best of both worlds.
This Hemp Home Design is all about Sustainability and will not sacrifice the Comfort Levels that I require.
Hemp Home Design 1
The above photo is a Catalan or Boveda Vault Style Roof. When I watched this You Tube Video of the Spanish Masons in action; I realized that this was the solution to building a roof and ceiling with little to no lumber and it will be energy efficient and save me money on utility costs! The Exterior water proofing layer has not been added to the design at this stage so that the viewer can the Masonry Work that comprises the Catalan Vault Style Roof System.
Hemp Home-Water Recycling-Water Collection System
The roof also will act as a Water Collection System that allows me to capture and store Rain Water for use in the Hemp Home. When a filter is added it can also act to provide the clean water needed for cooking, cleaning, and drinking.
The CAD drawing below is option 1 for the layout and design of the Hemp Home. My girl has already pointed out that I left out: Additional Bedrooms for Visitors and a Fireplace for heat- Luckily we’re in the design stage and not in the build stage of the Hemp Home. I’m sure this floor plan will change as we narrow down our needs and must haves.
Hemp Home Room List
2 Bedrooms- 1 Master Bedroom and 1 spare bedroom
1 1/2 Baths
Mechanical Room-Water Collection Point, HVAC Air Handler, Solar Inverter, Storage, Radiant Floor Heating
Dining Room / Living Room
Kitchen with Eat In counter
NOTE: These are not my final design plans stay tuned for additions and alterations to this Hemp Home Design as well as Build Notes on how and why I’ve chosen to build my future home with Hempcrete.
The fast growing Hemp Plant will enable me to Grow and Build a Hemp Home in 2 years!
My plans are to build this home in a rural setting where I can plant and grow a field of hemp to build this home. (If we decide to build in a City Setting I will purchase the Natural Hemp Fibers). While the Hemp is growing in the first year I will build the Stone – Rock Foundation for the home. After the Hemp field has grown, harvested, and prepped for building- I can then start building the walls of the home with a move in date in year 2!
If Hemp Building isn’t a solution to replacing the lumber needed for
building an energy efficient home I don’t know what is! Scotty
This type of Vaulted Roof Building is not new- Spanish Masons have been building these type of structures for years. See Mexico Insights:

If you are reading this I’m going to assume that you aren’t a google bot or bing bot and wear clothes in your daily activities. You are an actual human being who wears clothes.
Besides the obvious fact we wear clothes to cover our nakedness.
We humans wear clothes for protection: protection for our bodies: from the heat, from the cold, from rain and snow-summed all up from the Elements.
We protect ourselves with clothes against the Climate and Elements we live in.
Just as you wear clothes to protect yourself from the elements the various parts of a properly constructed energy efficient building are there to protect it from the elements while keeping the inhabitants comfortable.
While it may sound complex in Nature it’s really rather simple in content when talking about a Building.
The simple comparison in how warm and dryan Insulated Wind Breaker is to aSimple T-Shirt.
The Windbreakerstops theCold Airfrom reaching your skin and the Insulationis the stuff that keeps the cold from creeping close to your body.
While a T Shirt lets in both Air and Cold thus failing to keep you warm and dry. (This is the Framing of your Building. )
A Sweatshirt will help seal out a little cold but not for long. (This is the Insulation in your Building. )
But when a Windbreaker is put on over the Sweatshirt and T-Shirt it is such relief to be warm- almost anything is tolerable when in a Cold Windy Environment. (This is the Air Barrier in your Building.)
Caps or Hats (The roof of your Building see upcoming post-seeking sponsors)
Shoes and boots (The Foundation / Basement of your Building see upcoming post-seeking sponsors)
Examples 1 thru 5 when applied to a Building is your Buildings Envelope or Outer Shell.
The buildings we live and work in need protection too. Just as you will add layers against the cold to stay warm in today’s extreme climate. Your Building needs the same protection against the Elements of Heat and Cold.
The best protection against the Elements cold and heat from entering your building is: Insulation.
Insulation is your Number One Sourcefor keeping your building’s energy consumption as low as possible while staying comfortable.
Insulation keeps the Heat and Cold from creeping in your Building.
While building Insulation comes in many forms it basically performs the basic action that I mentioned above when talking about wearing a sweatshirt.
Insulation is there to keep out the heat and cold that make life uncomfortable– (to include the uncomfortable feelingyou get when you pay your local monthly Gas and Electric utility bills- for the over priced services they provide your building.)
Just as the Windbreaker stops the Wind from interfering with your body. The Air Barrier does the same for your Home or Office. Normal construction techniques have various Air Barriers All of which are designed to eliminate and reduce the cold or warm air from entering and leaving your Building. This is the second most crucial step in protecting a building against the Elements of heat and cold.
So what is the T-shirt used in this examples place in a building. The T Shirt in this example is the Buildings Walls and Roof. See the bare wall in this photo of the Benton Rehab Project
while the crew and I were rehabbing this building in St Louis. This is the framing without layers of Insulation or Air Barrier. It’s obvious that these walls will not keep out any heat or cold. Just as a t-shirt performs.
The Air Barrier and Insulation coupled with a few other areas of your building is your Buildings Envelope.

But first I’ll give you a little background on the Building
There were many clues for determining the age of the building.
First Clue was the type of Bricks used. When St Louis hosted the Worlds Fair. The city planners realized that housing was going to be needed for everyone and started building all the brick homes that are still being utilized all over the city today. It has to do with either the type of clay used to make the bricks or the way they ‘fired’ the bricks. Either way when you have the type of brick as the ones in this building you have a building using bricks that were made in the Late 1800s or early 1900s.
Lumber: We have found that Douglas Fir was used 80% of the time. True Dimensional Rough Sawn Lumber.

Rebuilding the back room
Supporting the 2nd Floor and Roof (we used a total of 5 Support Posts in a 6 Foot Area)
While Digging in the Pier Footings we found an old water tank/cistern that was used to supply water to a kitchen sink in the hand pump days.
Water Collection for re-use is/was a normal part of everyday living in the days gone past. The water was collected by the buildings eve troughs, gutters, and patio area (in the days gone past-they didn’t call it green building. It was called survival.)
