The strength within.
A complete X-ray of the wall, floor and foundation. One system, before a single layer moves.
03 / Construction technology
The whole system.
Every layer.
See through it.
Understand how it comes together.
Start with a complete X-ray, open the wall and floor layers, discover their materials, then watch the assembly come back together. One continuous view of the technology, from the inside out.
Explore the assembly
Inside the technologySkip the sequence
Concrete. From the inside out.
Nothing here is incidental.
The assembly opens. Concrete, insulation and structural support each reveal their place in the whole.
Every material. A purpose.
Concrete for structure. Insulation around the envelope. Heating and timber where the building becomes a place to live.
Precision brings it together.
The components return to the same coordinated assembly. Every connection, considered together.
Now see the whole picture.
From the structure to the finishing layers. One complete reference assembly, made tangible.

Illustrative reference. Project-specific engineering and approvals.

The X-ray shows an illustrative internal reinforcement cage with concrete cover and support blocks. It does not specify anchor bolts or structural connections. The visual explains how the reference components connect. Nominal layer dimensions and wall options are set out in the technical reference; the approved design determines the specification for each project.
The reference build-up
Every layer
has a role.
The cutaway shows one coordinated construction assembly, from the concrete facade to the prepared ground. These are reference details for discussion, not a specification for every site.
| Key | Layer or component | Reference |
|---|---|---|
| 01 | Concrete facade | 6 cm |
| 02 | Graphite EPS 031 wall insulation | 18 cm |
| 03 | Structural concrete wall | 14 cm |
| 04 | Floor finish | As specified |
| 05 | Underfloor heating | Within screed |
| 06 | Cement screed | 6 cm |
| 07 | EPS 100 floor insulation | 20 cm |
| 08 | Separation membrane | As specified |
| 09 | Concrete sub-base | 10 cm |
| 10 | Compacted sand fill | 50 cm |
| 11 | Concrete foundation stem | Project-specific |
| 12 | Moisture-resistant perimeter insulation | Project-specific |
| 13 | Gravel border and concrete kerb | As specified |
| 14 | Reinforced concrete strip footing | 30 × 60 cm |
| 15 | Lean concrete blinding | 10 cm |
Foundation dimensions, drainage, moisture protection and insulation are designed for the ground conditions, climate and local requirements. The model homes will use the specification selected and approved for that project.
A system that fits the brief
Three ways
to shape the wall.
Concrete on both sides. Space for services. Or a rendered exterior. Follow the layers at full scale and see how each reference assembly is built.

01 / Concrete sandwich
Concrete.
Both sides.
A structural concrete inner leaf and a concrete facade, with graphite insulation held between them. A substantial wall with an integrated exterior finish.

- 38 cm
- Reference U
- 0.164 W/m²K
- 6 cm facade
- 18 cm insulation
- 14 cm structure
02 / Interior service cavity
Room for
the details.
Concrete outside, insulation inside, then timber battens, a vapor-control layer and plasterboard. A coordinated space for interior services.

- Reference U
- 0.147 W/m²K
- 10 cm concrete

03 / Rendered exterior
A different finish.
A solid core.
A structural concrete leaf with graphite insulation on the exterior and a thin rendered finish. The external expression changes; the structural role stays clear.

Same concrete principle.
Different ways to finish.
Keep the complete reference in view. These are nominal assembly values; the final design determines the wall, openings, connections and performance requirements.
| Assembly | Reference build-up, outside to inside | Nominal thickness | Reference U-value |
|---|---|---|---|
| Concrete sandwich | 6 cm concrete facade · 18 cm graphite EPS 031 · 14 cm structural concrete · interior finish as specified. | 38 cm | 0.164 W/m²K |
| Interior service cavity | 10 cm structural concrete · 5 + 18 cm graphite EPS 031 · 2 cm timber battens · 0.2 mm PE vapor-control film · plasterboard lining. | 36.25 cm | 0.147 W/m²K |
| Rendered exterior | Thin exterior render · 18 cm graphite EPS 031 · 14 cm structural concrete · interior finish as specified. | 32 cm | 0.160 W/m²K |
Thicknesses and thermal transmittance values describe reference assemblies. Lower U-values indicate less heat transfer through the wall. Whole-building energy performance, moisture control, fire and acoustic requirements, structure and local approvals are assessed for the project. The film, finishes, openings and visual separation are illustrative; this sequence is not a dimensioned construction detail.
From the first drawing to the site
Precision is
a connected process.
Factory production is one part of the delivery. The value comes from coordinating the building, the manufacturing plan and the site as a whole.
Design & coordinate
Resolve the brief, structure, openings and service routes. Align engineering, dimensions and connection details before production begins.
Produce & check
Manufacture specified concrete and insulation components in controlled factory conditions. Coordinate dimensional checks and delivery sequencing while site preparation progresses.
Deliver & assemble
Confirm foundations, access and lifting plans. Deliver prepared elements for assembly, then coordinate the envelope, services and finishing trades.
Designed for the project. Approved for the place.
Engineering, transport constraints, ground conditions and local rules shape the final system. Scope, responsibilities, specifications and programme are agreed with the relevant specialists before delivery.
