Buying a tiny house is one of the best decisions you can make if you want to live affordably, sustainably and consciously. But it is not an impulse purchase. There are more choices involved than you might expect at first glance. In this guide, we discuss the 8 key points you should pay attention to.
Key takeaways
- Always start with your location and permit — this determines what is possible
- Choose a builder with demonstrable experience and references
- Decide on your finishing level upfront: building kit, basic or turnkey
- Factor in additional costs such as land, foundations and utility connections
- A modular tiny house offers more flexibility and expandability than a model on wheels
1. Define your goal: what will the tiny house be used for?
Before diving into models and prices, ask yourself this question: what will you use the tiny house for?
- Primary residence: You live there permanently. This places the highest demands on insulation, energy performance and permits.
- Care home (zorgwoning): A dwelling for a family member in need of care, in your garden. In Flanders, a simplified regime applies.
- Guest house or outbuilding: An extra space for guests or as a home office.
- Holiday rental: An investment that you rent out via platforms.
- Starter home: An affordable alternative for your first own home.
Each goal has different requirements in terms of size, finishing and regulations. Start here.
2. Research the location and zoning plan
The location determines not only your quality of life, but also what is legally permitted. In Belgium, regulations vary by region and municipality.
Check:
- Is the plot in a residential zone? This gives the best chance of obtaining a permit.
- Is it your own land or are you renting? If renting, discuss the possibilities with the owner.
- Are utility connections available (water, electricity, sewage)?
- What building regulations apply (maximum height, roofing, distance to plot boundaries)?

3. Choose between modular and on wheels
This is a fundamental choice that influences everything else:
| Modular (fixed foundation) | On wheels | |
|---|---|---|
| Floor area | Up to 112 m² or more | Typically max. 30-40 m² |
| Permit | Planning permission required | Grey area, depends on municipality |
| Comfort | Fully comparable to traditional home | More limited due to max width/height |
| Value retention | Good, comparable to property | Depreciates faster |
| Flexibility | Fixed in location, but expandable | Relocatable |
| Suited for | Permanent living, families | Singles, starters, temporary stays |
At Tiny House Heavens, we deliberately choose modular construction. This offers the most possibilities for permanent, comfortable living and most easily meets Belgian building regulations.
4. Pay attention to the finishing level
The finishing level has an enormous impact on both the price and your own effort:
House Kit (building kit)
You receive the load-bearing structure: steel undercarriage, timber frame and insulated floor, walls and ceiling. Ideal if you are handy or have your own contractor. You save significantly but invest time.
Basic finish
A fully finished home with basic installations, exterior façade and roofing. You can move in straight away. The most popular option for those seeking a good balance between price and comfort.
Optima (premium finish)
Turnkey with underfloor heating, hot water boiler, ventilation system and complete lighting. No worries, everything is taken care of. The highest price, but also the most comfort.

5. Check the build quality and materials
Not all tiny houses are equal. When comparing builders, look at:
- Construction method: Timber frame on steel undercarriage offers the best combination of strength and weight
- Insulation: Minimum 150 mm wall insulation for comfortable living in all seasons
- Cladding: Durable materials that require little maintenance
- Roofing: Metal roof (long-lasting) vs. shingles (cheaper but shorter lifespan)
- Windows and doors: Double or triple glazing for energy performance
Always ask for the technical specifications and compare them objectively between builders.
6. Calculate the total costs
The purchase price is only part of the story. Create a total budget that also accounts for:
- Land purchase or lease
- Permit costs
- Foundation works
- Utility connections
- Transport and installation
- Possible notary fees
- Furnishing costs

7. Choose your builder carefully
The choice of your builder is perhaps the most important decision. Pay attention to:
- Experience: How many tiny houses has the builder already delivered?
- References: Can you visit previous projects or read customer stories?
- Transparency: Is the quote detailed? Do you know exactly what is included?
- Warranties: What warranties are offered on structure, installations and finishing?
- Communication: Is the builder accessible and clear in communication?
- Location: A nearby builder makes site visits and aftercare easier
Always request multiple quotes and compare them on content, not just price.
8. Think about the future
A tiny house is not a temporary solution — it is an investment in your lifestyle. Think about:
- Expandability: Can the modular system be expanded later? With modular constructions, this is often possible.
- Growing family: Does the model still work if your family grows? Consider a larger model.
- Resale: Modular tiny houses in a fixed location retain their value better.
- Energy performance: Invest in good insulation and sustainable installations — this saves money for years to come.
Frequently asked questions
How long does it take to have a tiny house built?
Build time varies from 6 to 16 weeks after ordering, depending on the model and finishing level. Add the permit procedure (1-4 months) and foundation works on top of that.
Can I design my own tiny house?
Most builders work with fixed models that you can customise. Fully bespoke designs are also possible but cost more and take longer.
Is a tiny house suitable for year-round living?
Absolutely, provided the tiny house is well insulated and equipped with adequate heating and ventilation. Modular tiny houses with 150-200 mm insulation offer the same comfort as a traditional home.
