Dome homes are becoming more sought after because of their unique shape, energy efficiency, and durability. These homes are perfect if you need a sustainable living space or a home that can withstand storms.
This dome house buying guide focuses on what you need to know before purchasing, including home varieties and prices, as well as permits, insurance, financing, and upkeep.
We will discuss the important aspects of dome house ownership in this guide. Understand the different types to choose from, how to calculate the numerous additional expenses, and how to sidestep zoning complications prior to building or buying.
1. Understand Different Types of Dome Homes
Dome houses are more diverse than you might imagine. Some are designed to be built quickly, and others can last over a century. Consider these most common forms of dome homes:
1. Geodesic Domes
Geodesic domes, like most dome houses, are built from triangle-shaped panels that round up together. They represent one of the most common types of dome homes.
Key Features:
- Lightweight steel or wood makes up the materials of these houses.
- The triangular shape provides even distribution of structural stress.
- The energy efficiency of geodesic dome houses, coupled with their ability to prevail in harsh environmental conditions, makes these homes strong.
Why Choose Geodesic Domes? Individuals looking for rapid installations and flexible layouts will find geodesic domes ideal for their needs. These can be small backyard studios or permanent residences.
2. Monolithic Domes
These are created by spraying concrete on a dome-shaped inflatable mold. These are a one-piece structure that is extremely durable.
Key Features:
- Fire- and floodproof.
- Tornado and earthquake resistant.
- Extremely fire- and flood-proof and earthquake-resilient.
- Exceedingly long-lasting and require minimal maintenance.
Why Choose Monolithic Domes? Suitable for buyers looking for a long-term investment property, these homes require low maintenance. There are higher initial costs and longer build durations.
3. Prefabricated & Modular Domes
These homes are manufactured in a factory and then transported in parts to the construction site. You or a builder assemble these on location.
Key Features:
- Comes as a kit and is designed in an initial stage for easier construction.
- Lower cost in these orders that are not custom-made.
- Quicker assembly.
Why Choose This Type? Suitable for those seeking low cost and easier construction, these domes offer little to no customization.
2. Know the Real Costs Involved
Constructing or purchasing a dome home brings expenses beyond materials. Let’s analyze the possible costs:
Initial Construction Costs
Home size, materials, and design influence the price. As with other homes, dome homes usually fall within a square foot construction price range of $80 to $250.
- Modular dome kits $80 to $150/sq ft
- Custom-built domes $150 to $250/sq ft or more
Prices will be higher for more complex designs with larger, luxury, and intricate finishes.
Additional Expenses
Apart from the dome structure, other expenses to consider are the:
- Land purchase (varies by location)
- Site prep: soil tests, leveling the ground, and clearing vegetation.
- Utility connections: for water, electricity, sewage, and sometimes solar.
- Interior work: plumbing, appliances, flooring, and walls.
- Landscaping: green spaces, fences, and even access ways.
These will cost an additional $20,000 to $100,000.
Hidden Costs and Ongoing Maintenance
These are more of an initial investment but include:
- Doors and windows
- Permits
- Specialized inspections
- Permits and inspections
- Hygienic system upgrades
These expenses will require a dedicated budget reserved solely for the unrevealed operational costs.
3: Zoning, Building Permits, and Local Regulations
Dome homes are still considered unconventional, which may cause problems with local rules.
Permit and Zoning Challenges
Some regions may not specify regulations for dome homes; this could hold up your permit authorization.
- Make sure to check the zoning regulations beforehand.
- Confirm that domes are permitted in residential zones.
- Plan and engage with local authorities in advance.
Building Code Compliance
Conduct safety compliance inspections for dome homes.
- Adhere to safety requirements for wind, snow, and earthquake threats.
- Provide adequate fire escape routes and airflow for fires.
- Complete all building inspections before occupancy.
This process is simpler when you hire an experienced dome builder.
4. Financing and Insurance Considerations
Obtaining financing may be difficult, as banks and insurance companies could be unfamiliar with dome homes.
Challenges in Securing Traditional Loans
Standard loan requirements may not be met by some homes, as most lenders focus on traditional homes.
- Inquire about green home loans or loans for alternative housing.
- Inquire with your builder if they work with any financing partners.
- Credit unions tend to be more approachable than large banks.
Insurance Options
Due to the unfamiliar nature, some insurance companies charge a higher premium.
- Seek out companies specializing in dome homes for insurance.
- Provide complete specifications and structural descriptions.
- Look beyond the primary offering in some home insurance to get a better rate.
Accuracy in documentation provides reliable insurance for some homes.
5. Choosing the Right Builder and Materials
The choice of builder and materials directly influences the success of your dome home.
Experience Matters
Make sure your contractor is a dome home specialist; do not settle for general practitioners.
- Find out how many dome homes they’ve built.
- Make sure to check references and visit past jobs.
- Ensure they know the specific difficulties related to the dome shape.
Quality of Materials
The choice of materials directly affects the durability and energy efficiency of the home.
- Wood is not as energy-efficient as steel or concrete frames.
- Use high-grade insulation (spray or rigid foam).
- Use double- and triple-glazed windows.
Good materials will reduce energy expenses and increase the dome’s lifespan.
6. Assessing Resale Value and Marketability
Dome homes target a specific audience, which impacts how quickly they can be sold as well as for how much.
Niche Market Appeal
Dome homes cater to eco-conscious or adventurous buyers.
- The round shape is not appealing to everybody.
- There may be a smaller pool of buyers actively looking for domes.
- Distinctive homes might require a longer sales timeframe.
Maximizing Resale Opportunities
Make your dome more attractive by:
- Offering a desirable configuration (2 to 3 bedrooms and 2 bathrooms).
- Incorporating modern kitchens and solar panels.
- Positioning the home close to urban areas, schools, or popular nature spots.
Even if you do not intend to sell your home anytime soon, factoring resale value during planning will be beneficial.
7. Dome Home Maintenance and Longevity
Although dome homes require minimal upkeep, they are not completely neglectable.
Long-Term Maintenance Needs
Make sure to inspect your dome periodically to maintain its optimum condition.
- Perform exterior surface cleaning at least once every year.
- Inspect the window and seal for potential leakage.
- Make sure air circulation is functioning correctly.
Neglecting small problems tends to spiral into more serious problems down the line.
Durability Expectations
If properly built, the dome can withstand the test of time for several decades, and in some cases even for a century.
- Geodesic domes: 50 to 75 years
- Monolithic domes: more than a century
- Prefab domes: 30 to 50 years
If you build with good quality, your dome is likely to outlast the majority of traditional houses.
8. Pre-Purchase Checklist
Prior to proceeding with your purchase, make sure you go through this preliminary checklist:
- Set up a budget that has a construction cost, purchase a plot of land, and account for the additional costs.
- Make certain that you have access to potential loans and financing.
