Sun, wind, privacy and connection back to the plan — terrace or annex readiness checked before any order.

You want more living space beyond the façade — covered outdoor rooms and annexes that feel like part of the house. Home extensions and bioclimatic pergolas are supplied and installed as one outdoor architecture package.

Sun, wind, privacy and connection back to the plan — terrace or annex readiness checked before any order.
Structure, anchors and finishes locked to the architecture and openings line where present.
Factory lead times aligned with interior or joinery works — outdoor and indoor stay on one programme.
Fit and commission in a weather-ready window — shade, open or enclosed when the programme asks for it.
Outdoor space and annexes often feel bolted on. The need is extensions and terraces that read as part of the home — comfortable in Luxembourg weather, precise at every junction.
We treat annexes and outdoor rooms as architecture: orientation, privacy and connection back to the interior plan come first — before choosing a pergola or enclosure system.
Thresholds, flooring, glazing and lighting are coordinated so the move from inside to outside stays seamless — supply and install under the same ACJ Lux desk.




The home gains usable space beyond the façade — shaded when needed, open when wanted, enclosed when the programme asks for it.
Continuity holds: delivery does not stop at the glass line.
