Custom Dome Planning

 

Custom Planning

Most of our customers have us create a custom dome plan.  We design your dome based on your family and your family’s lifestyle.  We look at your site and study the contours, flow and other layout considerations.

At Natural Spaces Domes, we have been designing dome homes since 1971. All in-house designs utilize the design expertise of Dennis Odin Johnson, founder/owner of Natural Space Domes. Prior to 1971, Dennis worked as an architectural designer/project manager for Gingold-Pink Architects, in Los Angeles and Minneapolis/St. Paul, for 10 years.

Our massive private library of over 1500 custom dome plans along with 45 years of in-house dome design experience will help create a dome home that is truly yours.

We offer interior planning kits to get you started and help you layout your own preliminary custom plan.

Natural Spaces Domes would like to have the opportunity to create your plan with you – our experience and your dreams will make your dome come true.

Custom Preliminary Plan Services

To start the custom planning process, we need you to select a plan from our plan design library, making your changes, or develop your own sketches or plans, preferably using our Interior Planning Kit. Complete our Customer Design Information Sheet and send all of the information to us. We will then review your project and give you an estimate of total design costs and a work authorization to start your dome plans. 50% deposit required, balance due upon completion.. An average amount for custom residential dome preliminary drawings is shown below: (Price includes floor plans. Add for elevations, section, etc.)

Preliminary drawings include 2 blueprint copies and 2 blueprint copies as revisions are made. When completed, up to 3 complete sets of blueprints are provided. Additional sets are available @ $2/page for 18″ x 24″ ($3/page for 24″ x 36″), plus mailing, $10 min.

Custom Construction Planning Services

We will develop your custom preliminary plans into more detailed digital CAD construction drawings. You need these to build your dome and apply for a building permit. Custom dome construction drawings will vary in cost based on the dome size. Your plan complexity and the amount of revisions during the drawing phases can create additional costs, which would reflect the higher costs shown below or even increasing these costs. A signed Work Authorization (with defined costs) is required to start your custom construction drawings. 50% deposit required. An average amount for custom residential dome construction drawings is shown below:

Price

Models 500 to 625 – 26′ to 29′ diameter $1,000 – $3,000
Models 650 to 950, 30′ to 36′ diameter $1,250 – $3,250

Models 1900 & 2000, 50′ to 51′ diameter $2,500 – $5,000

Construction drawings include 3 blueprint copies as revisions are made and a set of digital pdf’s will also be emailed. When completed, 3 complete sets of blueprints are provided. Additional sets are available @ $2/page for 18″ x 24″ ($3/page for 24″ x 36″), plus mailing, $10 min.

Engineering Drawings

The Natural Spaces Domes shell system is pre-engineered to meet or exceed standard building codes regarding snow load (100lb/sf), wind load (150 mph) & earthquakes (Zone 4 or E). We will provide a standard dome shell engineering analysis upon request. This analysis will be stamped by an engineer registered in your state (assuming you live in the United States). Our dome shell system is also designed to meet extreme snow (140lb/sf) or wind (200+ mph) load conditions. However, the engineering for these conditions will be handled individually with engineering prices quoted per project. The standard dome engineering pamphlet is available prior to purchasing our dome for a $150 fee. This will then be credited to your Natural Spaces Domes purchase.

A complete engineering analysis and signed, stamped plans for your custom dome or non-dome shell portions of your project may be required by your building inspection department. Costs for this, if required, vary considerably depending on the plan and building code requirements. Costs can vary from $500 to $2000 for partial engineering of parts such as the foundation. Complete project engineering for multi-story domes will vary from $2000 to $6000. Multi-dome projects, hurricane/earthquake areas and more complex designs may push costs towards the high end of that range. Most building inspectors do not require this engineering but some larger cities and a few states have mandatory requirements. We can talk to your building department to learn about their requirements.

Custom architectural/engineering drawings are signed and stamped (if required) by Paul Durand, PE, SE. He is experienced with domes and licensed (or affiliated) in all 50 states and can provide dome engineering calculations for foreign engineers, saving them valuable time. Custom architectural, engineering, mechanical and electrical drawings can also be provided for commercial, industrial and institutional projects.

MacDome Budget

Natural Spaces Domes can provide a complete itemized cost estimate of your entire project. It is an 11 page worksheet with over 475 itemized lines utilizing our Macintosh computer and an Excel spreadsheet. We estimate both materials and labor (separate) for everything and then show you square footage cost estimates. Prices for material and labor will vary depending on location and can be easily accommodated. Once completed, you can request an active Excel spreadsheet to use as your budget.

       MacDome Budget costs depend on complexity of the project: $450 – $900

MacEnergy Calculations

Working with our own computer spreadsheet program, Natural Spaces Domes will develop the heat loss calculations for your dome and its site. This is often required by your local building department. Our program will also suggest the correct size for your furnace based on these energy calcs. Our program also shows you, by percentages, how much heat is lost thru the individual components of your particular structure such as; windows, doors, insulated wall and roof areas, framing, etc. The final chart shows you the actual yearly heating costs based on 4 different fuel sources. For domes located in Minnesota, we will provide an analysis and print out of the Minn-Chec computer program with the MacEnergy Calc at no extra charge (beyond the basic cost of the MacEnergy calc) upon request.

       MacEnergy Calc costs depends on size of project: $350 – $900


Using digital CAD programs we can provide realistic 3-D drawings, showing you your domes in a natural setting.

We have several clients that have utilized a local architect to provide their dome design. The designs and renderings below were done by Nathan Riggle, an architect in Tucson, Arizona. We provided the basic 3-D domeshell imaging and Nate worked with the clients to create their perfect plan. Once we explained some of our domes structural characteristics and all of its possibilities, Nate used his architectural and creative abilities to produce a very imaginative design. If you have an architect you would prefer to work with, we can email CAD files.

As another option with our computer drawn custom plans, we can provide 3-D exterior views from any vantage point around the dome. We do not have to do 3-D construction drawings of your dome. We can also add color and texture. Easy for us and cheaper for you.


3-D Animated tour of your Dome

We can create an animated “fly around” and “walk through” of your dome. This animation can be viewed frame by frame letting you study your dome in detail. We can add textures, patterns and color to your dome images. The windows and skylights can be transparent, allowing you to look through, into the interior. We can change the colors, letting you compare color schemes. The cost varies with the total length of the animation (the total number of “frames” created), the complexity and detail required to show your dome. We first need to create basic 3-D computer construction drawings, which are not included in this cost.

Computer Animation: $1,000 – $4,000
