Our process

How construction works

From the first consultation to the completed structural shell, the whole process is divided into four stages: design, production, and on-site assembly.

  1. 01

    Initial meeting

    Commercial proposal

    Consultation, discussion of the brief, preparation of a preliminary project, and budget estimate.

  2. 02

    2-3 weeks

    Project adaptation

    If you already have an approved architectural project, we will adapt it to SIP technology and structural requirements.

    If you do not yet have a project, our architects will develop one and help with approval so construction can begin.

  3. 03

    2-3 months

    House kit manufacturing

    Production of the house panels and elements according to the project documentation, followed by delivery to the site.

  4. 04

    ~1 month

    Assembly

    Completed house shell on site: installation of walls, floors, and roof.

Smarter building

Modern & eco-friendly technology

SIP panels combine structure and insulation in a single factory-built element — enabling faster, cleaner, and more predictable construction.

What are SIP panels?

SIP panels are a modern construction technology used widely around the world. They make it possible to build warm, reliable homes quickly, efficiently, and cost-effectively.

There are several ways to manufacture SIP panels. We use the most advanced method: hot pressing with high-pressure filling.

This creates a strong bond between layers, precise geometry, and consistent quality in every panel, which means the house is assembled faster, lasts longer, and costs less to operate.

  • Continuous insulation across the entire house structure, reducing heat loss and lowering heating costs
  • Factory precision of OSB boards down to fractions of a millimeter for fast, clean installation without rework
  • High-pressure production for strength, durability, and structural stability

Precision manufacturing

Hot-press production keeps panel geometry stable and dimensions consistent from drawing to assembly.

Thermal performance

Continuous insulation through walls, floors, and roof reduces thermal losses and supports lower operating demand.

Frequently asked questions

Common questions about SIP construction, timelines, and working with modularcasapt.

SIP (Structural Insulated Panels) are load-bearing building panels made from an insulating core bonded between two structural facings. Because they are factory-manufactured, they arrive with precise dimensions, consistent quality, and strong thermal performance. This allows faster assembly on site and a more continuous insulated envelope than many traditional wall systems.

Yes. When the project is designed with the right wall build-up, ventilation strategy, and detailing for the local climate, SIP homes perform very well in Portugal. Their continuous insulated envelope helps reduce condensation risk, limits uncontrolled air leakage, and improves thermal comfort through both humid winters and hot summer periods.

For a structural shell, SIP construction typically takes around 3 months from technical preparation to final on-site assembly. In practical terms, the process usually includes project adaptation to SIP logic, factory manufacturing of panels, delivery coordination, and then fast installation on site. Compared with many conventional methods, this reduces delays, improves precision, and shortens the critical construction phase.

Yes. SIP houses are known for high energy efficiency because the building envelope combines structure and insulation in one system. This helps reduce thermal bridges, lowers heating and cooling demand, and makes indoor temperatures more stable and comfortable throughout the year.

Yes. Existing architectural projects can usually be adapted to SIP construction without losing the main design intent. The adjustment process typically focuses on spans, junctions, panel module logic, and buildable detailing so that the house keeps its architectural character while becoming compatible with SIP manufacturing and assembly.

Yes. We can provide technical information on panel composition, performance values, assembly logic, and supporting documentation relevant to the project stage. For partners, architects, and serious enquiries, this can include the key specifications needed for design coordination, approvals, and feasibility review.

Yes. The sample house is located in Figueira-do-Foz and can be visited by appointment. During the visit you can see the build quality, spatial feel, finishes, and overall comfort of a real completed SIP home, which helps make the system much easier to evaluate than from drawings alone.

Yes. We work with architects, developers, construction companies, and investors who want to integrate SIP technology into residential projects in Portugal. Collaboration can include project adaptation, technical coordination, delivery planning, and support during the transition from concept to buildable SIP system.
