How Much Does a SIP Panel House Cost: What Makes Up the Price

The question of cost is one of the first that clients ask when planning construction. SIP panel construction is often seen as “cheaper than traditional”, but in practice it is more accurate to speak of a predictable and optimised cost rather than simply a low price.
The Onlysip team explains what the cost of a SIP panel house is really made up of and how the final budget is formed.

Why the price of a SIP house is not a fixed figure

As with any construction, the price of a SIP house depends on many factors. There is no universal “per square metre” cost that would be equally accurate for all projects.

The budget is affected by:

• the floor area of the house;
• the number of storeys;
• architectural complexity;
• the specification level;
• the type of foundation;
• engineering solutions.

That is why Onlysip works with custom design and a detailed estimate.

The main components of the cost of a SIP panel house

Design

The design is the foundation of the budget. A well-developed design makes it possible to:

• optimise costs;
• avoid rework;
• fix the quantity of materials.

In SIP construction, the accuracy of the design is critical, because the panels are manufactured to specific dimensions.

SIP panels and the house kit

The panels themselves account for a significant share of the cost. The price depends on:

• panel thickness;
• the type of insulation;
• the area of walls and floors;
• the complexity of the structure.

The house kit is manufactured at the factory, which makes it possible to control quality and avoid material overuse.

Foundation

SIP houses are lighter than brick ones, so the foundation is usually cheaper. The most common options are:

• strip foundations;
• pile and grillage systems;
• a slab — if needed.

The foundation type is selected individually depending on the soil.

Assembling the house shell

Installation includes:

• installing the panels;
• floors;
• the roof.

Thanks to the speed of SIP technology, installation costs are lower than in traditional construction, and the timelines are much shorter.

Building services

The budget includes:

• electrics;
• water supply;
• sewerage;
• heating;
• ventilation.

The solutions are selected with the energy efficiency of the house in mind.

Finishing and specification

The final cost depends largely on the level of finishing:

• basic specification;
• “ready for final finishing”;
• turnkey.

Onlysip offers turnkey construction, so the client knows the final amount from the outset.

Why a SIP house pays off in the long run

Even when comparing the initial budgets, the running costs of a SIP house are significantly lower:

• lower heating costs;
• fast warm-up;
• a stable indoor climate.

Over time, this adds up to noticeable savings every year.

How Onlysip fixes the budget

Onlysip works on the following principle:

• a detailed design;
• a transparent estimate;
• the cost fixed at the start.

This helps avoid situations where construction “gets more expensive as the work goes on”.

Conclusion

The cost of a SIP panel house is made up of specific components and lends itself well to planning. SIP technology makes it possible to optimise the budget without compromising quality, and the turnkey construction format from Onlysip gives the client financial transparency and peace of mind. That is why SIP houses are increasingly becoming a conscious choice rather than a compromise.
