1. Define the project before choosing products
Start with the use case. Is the space a full-time dwelling, guest space, rental unit, cabin, office, or occasional retreat? The answer affects size, systems, comfort expectations, storage, access, and local requirements.
Write down the non-negotiables first: approximate size, number of occupants, sleeping needs, bathroom needs, kitchen requirements, mobility considerations, climate, and how often the space will be occupied.
2. Investigate the site before locking the design
A design that works on paper can become impractical on a particular property. Investigate access, setbacks, utilities, water, wastewater, terrain, drainage, emergency access, and local zoning or building requirements.
For an ADU or permanent structure, local rules can be especially important. For a movable tiny home, the legal treatment can depend on how and where it is used. Do not assume a tiny-home label answers the regulatory question.
Use local government information as the starting point for requirements, and involve qualified local professionals when the decision requires site-specific or technical judgment.
3. Plan the systems as part of the project
Power, heating and cooling, water, sanitation, and ventilation are not afterthoughts. Their requirements can affect space planning, equipment locations, electrical capacity, plumbing routes, and operating cost.
Decide whether the project will be grid-connected, partially off-grid, or fully off-grid before assuming that a particular product is the answer. Off-grid living can change the infrastructure required to provide the same basic services.

4. Build a planning budget, not a false-precision number
Use broad cost ranges to understand scale. Separate the building itself from foundation or trailer, utilities and systems, planning or permits, and major site-development costs that may not be included.
Then identify which assumptions have the greatest uncertainty. Those are the numbers that deserve local research first.
5. Sequence decisions before purchases
- Define purpose, occupants, size, and permanence.
- Investigate the site and local requirements.
- Choose a preliminary construction and foundation approach.
- Plan major systems and utility strategy.
- Build a broad budget and contingency thinking.
- Develop the design and construction sequence.
- Only then compare products and make major purchases.
This sequence helps prevent a product choice from quietly dictating a project that has not yet been fully defined.
