Comporta 107 House by dEMM Arquitectura: Beach House Architecture Review

Comporta 107 House by dEMM Arquitectura is a beach house set among pine forest, rice fields and sand dunes in Comporta, on Portugal’s Alentejo coast. Completed in 2023, the house is built from two contrasting volumes: a warm timber ground floor that opens onto the dunes, and a concrete upper volume that appears to float, supported only at its outer edges. This review explains the design concept, structure, materials and landscape strategy of Comporta 107 House, and closes with practical lessons for Pakistani homeowners and architects designing coastal homes, farmhouses and weekend retreats.

The Setting: Dunes, Pines and Rice Fields

Comporta is known for its long, quiet beaches, umbrella pines and rice paddies. Development there tends to be low-rise and closely tied to the landscape. The architects took the untouched, untamed character of the local beaches as their starting point and set out to recreate the dune environment around the house, with its rolling sand and native vegetation.

This approach reflects a wider shift in coastal architecture. Instead of flattening dunes and replacing them with paving and imported grass, architects increasingly keep the natural ground and its plants. Dunes help hold sand in place, support local wildlife and need far less water and maintenance than lawns. For owners, the result is a house that feels calmer, looks established from the first day and costs less to keep.

Rather than placing a building on a manicured lawn, the design lets the sand and dune planting run up to the walls and into the patios. The house is meant to feel like part of the landscape rather than an object placed on it.

Design Concept: Two Contrasting Volumes

Comporta 107 House is organised as two sleek volumes stacked on top of each other, each with a distinct character.

The contrast is deliberate. The lower floor feels light, permeable and connected to the ground. The upper volume feels heavy and protective, yet its minimal supports make it seem to hover above the timber base.

Structure: A Floating Concrete Volume

The most striking engineering feature is the first-floor concrete volume supported only at its outer edges. Removing central supports frees the ground floor beneath, creating an uninterrupted space for the living room and kitchen.

Structures of this kind depend on careful engineering. The concrete volume works like a deep beam or a box girder, with its walls and slabs acting together to carry loads to the supports. Reinforcement detailing, concrete quality and formwork accuracy all matter, especially when the concrete is left exposed and every imperfection is visible.

Why it matters for the plan

• The living room and kitchen are open, with no columns breaking the space.
• Full-height windows can slide away completely, opening the interior to the pool and patios.
• The ground floor reads as a lightweight pavilion beneath a sheltering roof.

Indoor-Outdoor Living

The ground-floor patios were designed to blend with the sandy terrain and dune vegetation, extending the outdoors into the social spaces. These areas can also be fully enclosed when needed, preserving the feeling of being both inside and out.

Generous ceiling heights and full-height windows that open fully allow daylight and breezes to fill the living spaces. The boundary between interior and exterior becomes almost invisible, and the pool, terraces and gardens read as extensions of the house.

Materials and Texture

The material palette is restrained and closely tied to the setting.

• Exposed concrete: used to create both solidity and, through careful shaping, visual lightness.
• Custom textured timber: a wood finish developed specially for the project and used on both exterior and interior surfaces.
• Corten steel: a weathering steel whose rust-coloured patina complements the pine and sand tones.
• Natural stone: large, sand-coloured stones, some containing embedded fossils, recalling the beach.

Using the same timber inside and out reinforces the continuity between interior and landscape.

Landscape and Biophilic Design

The architects describe a biophilic approach, integrating nature into every part of the design. Native plant species were selected and combined with the architecture, from the bedrooms to the social areas. Outdoor spaces, including terraces, balconies and gardens, are designed to celebrate the natural setting and to age well. The surrounding pine forest blends into the planned dune vegetation that wraps the pool area.

How the Design Responds to Its Context

Lessons for Pakistan

Pakistan has a growing market for weekend homes and farmhouses on the outskirts of Lahore, Islamabad and Karachi, as well as coastal houses near Karachi and Gwadar. Comporta 107 House offers useful ideas, but they must be adapted to Pakistan’s climate, materials and regulations.

What translates well

• Let the landscape lead. Native, drought-tolerant planting reduces water use and maintenance compared with large lawns.
• Column-free living spaces. Deep beams, transfer structures or post-tensioned slabs can create open living areas, but they must be designed by a qualified structural engineer under the Building Code of Pakistan, including seismic loads.
• Outdoor rooms. Verandas, courtyards and shaded patios are already part of South Asian architecture and suit our climate well.
• Honest materials. Exposed brick, fair-faced concrete and natural stone can age gracefully with low maintenance.

What needs adapting

• Heat and sun. Large glazing must be shaded from the south and west, and high-performance glass and roof insulation are essential in Pakistani summers. Comfort guidance such as that from ASHRAE can help size shading and cooling.
• Coastal corrosion. Near the sea in Karachi or Gwadar, salt air attacks steel. Increase concrete cover, use suitable cement and coatings, and choose metals carefully.
• Dust and insects. Fully opening facades need screens and seals for dust storms and mosquitoes.
• Security. Glass-walled ground floors need secure shutters or screens, especially in farmhouses.

Planning a Farmhouse or Coastal Home in Pakistan

Owners who want a landscape-led house like Comporta 107 can follow a clear sequence to avoid costly surprises.

Off-grid features also make sense for remote plots: rooftop solar with battery storage, rainwater harvesting, a water treatment system and a properly designed septic system where no sewer is available.

Conclusion

Comporta 107 House shows how a holiday home can sit lightly in a sensitive landscape. Its floating concrete volume, warm timber base and dune garden create a strong sense of place with a simple palette. For Pakistan, the lessons lie in letting landscape and climate guide design, using honest materials, and engineering open spaces properly.
