Modular house or frame house: which choice is smarter today?

When choosing what type of house to build — modular or frame — many people wonder which option is more durable, economical, and faster to construct. Both types appear modern, warm, and energy-efficient, but their differences become clear once you look closely at the construction process, cost, and quality.

Construction method and duration

A modular house is built in a factory from pre-made modules that are later transported to your plot and assembled within a few days. The entire project — from order to keys — often takes only 2–6 months. Since most of the work is done indoors, construction is not affected by weather conditions, which helps avoid delays.

A frame house, on the other hand, is assembled directly on-site. This means that construction depends on the season, and the process often takes 6–12 months. However, some homeowners appreciate this as it allows them to more closely monitor progress and make adjustments along the way.

Cost and quality

In terms of price, modular houses are often cheaper because the manufacturing process is more efficient and expenses are clearly planned before construction begins. Clients receive a detailed cost estimate, and the risk of exceeding the budget is minimal. Moreover, high quality control in the factory ensures precision and airtightness that often surpasses that of houses built entirely on-site.

Frame houses may cost slightly more due to longer construction times and additional work. However, a well-built frame house can also be durable and long-lasting — everything depends on the quality of materials and the professionalism of the builders.

Energy efficiency

Both types can achieve the highest A++ energy class. However, modular houses often offer better airtightness, as insulation materials are installed in a controlled factory environment — precisely and without “thermal bridges.” These houses frequently include heat pumps and ventilation with heat recovery, making them very economical to maintain.

Frame houses can also be highly energy-efficient if the design includes sufficient insulation and airtight construction. However, achieving this depends more on the builder’s diligence on-site

Conclusion

If you value speed, price transparency, and a precise result, a modular house is a modern and rational solution.
If you prefer a traditional building process and want more flexibility on-site, a frame house can also be an excellent choice.

Both options can become your dream home — the key is to choose the one that best fits your needs, budget, and lifestyle.
