Luxury Home Architect Cornwall
Luxury contemporary homes, coastal living and architectural detail in Cornwall
How Keynvor brings together light, craft, comfort and modern coastal living in Mawgan Porth
Luxury in contemporary architecture is not simply about scale or spectacle. It is about how a home feels to live in. It is found in light, proportion, atmosphere, material quality, quiet privacy and the ease with which spaces support daily life.
At ARCO2 Architecture, luxury contemporary homes are designed around people and place. The most successful homes are not imposed upon a site. They are shaped by it, responding to landscape, climate, lifestyle and the emotional experience of living there.
Keynvor in Mawgan Porth is a contemporary sustainable home that reflects this approach. Positioned above the bay in North Cornwall, the house combines generous living spaces, carefully framed sea views, natural materials and low energy design to create a calm and refined coastal retreat.

Luxury defined by experience
The brief for Keynvor was to replace an existing 1970s holiday home with a sustainable modern dwelling that captured the essence of its coastal setting. The clients wanted a home that opened towards the sea, drew in natural light and created a peaceful place for both gathering and quiet reflection.
This is where contemporary luxury becomes more nuanced. The design is not about excess. It is about creating a home that feels effortless, generous and deeply connected to its surroundings.
Living spaces are arranged on the upper floor to make the most of the panoramic views across Mawgan Porth Bay. Bedrooms and quieter private areas sit below, opening towards gardens, courtyards and sheltered outdoor spaces. The result is a home with a clear sense of hierarchy, where social spaces feel open and uplifting while private spaces feel calm and protected.
For clients seeking a luxury home architect in Cornwall, this balance between openness and retreat is often central to the design process.
Arrival, atmosphere and architectural journey
A luxury home should reveal itself gradually. At Keynvor, the approach from Tredragon Road was carefully considered as part of the architectural experience.
Visitors descend through the landscape by a series of broad stone steps, moving away from the surrounding built environment and towards glimpses of the coast. Partial views open across the sedum roof, framed by slate hanging, dark timber cladding and planted landscaping.
This sense of arrival creates a deliberate rhythm. Rather than presenting everything at once, the architecture uses moments of concealment and reward. The journey into the home becomes part of the experience, heightening the sense of retreat and connection to place.
The entrance itself introduces the quality of the design. A dark exterior gives way to a light filled interior, where natural oak panelling rises towards the vaulted ceiling and draws the eye through the home. This contrast between enclosure and openness is one of the defining qualities of the project.
Open plan living with depth and warmth
The first floor brings the kitchen, dining and living spaces together in a generous open plan arrangement. This level is designed to capture the best of the views, but also to create a comfortable and human scaled place for everyday living.
The kitchen and dining area sit within a refined contemporary interior, with warm materials and carefully integrated details bringing softness to the architecture. The main living space then opens into a dramatic double height volume, where expansive glazing frames the bay and fills the home with changing coastal light.
A mezzanine above adds further richness to the spatial arrangement. It provides an elevated view back into the living space while retaining a strong visual connection to the sea. Used as a private office and storage space, it allows the home to support modern life without compromising the clarity of the main living areas.
This is contemporary residential design at its most useful. Beautiful, but practical. Refined, but liveable.
Spaces for gathering and retreat
Luxury contemporary homes need to support different modes of living. They must be able to welcome guests, bring people together and offer quieter spaces for solitude.
At Keynvor, the open plan living space provides the generous social heart of the home. Alongside it, a more recessive snug creates a quieter, more intimate room with access to a private balcony. The spaces are separated by a feature ethanol burner set within a copper surround, adding warmth, texture and a sense of crafted detail.
This creates a subtle but important shift in atmosphere. The main living space feels expansive and connected to the view. The snug feels more enclosed, tactile and contemplative.
That ability to move between openness and privacy is central to the success of a luxury home. It allows the architecture to support the changing rhythms of family life, hosting, working and rest.
Materiality, craft and coastal character
The material palette at Keynvor was chosen for durability, sustainability and character. Slate, timber, zinc, oak and natural finishes give the home a strong connection to its coastal setting while allowing it to age gracefully over time.
Externally, slate hanging, timber cladding and zinc detailing respond to the exposed coastal environment. These materials were selected for their robustness and low maintenance qualities, but also for the way they will patina and soften with age.
Internally, the atmosphere is warmer and more tactile. Oak panelling, natural textures and carefully curated finishes create a sense of calm refinement. Interiors by Nicola O’Mara continue the same coastal sensitivity, using simple, warm and light filled spaces to support the architectural vision.
This kind of restrained material richness is often more powerful than overt luxury. It gives the home depth, longevity and a quieter sense of quality.
Indoor and outdoor living shaped by the site
The steep hillside site at Keynvor created both challenge and opportunity. Rather than treating the garden as a separate element, the architecture and landscape were designed together.
Green roofs, biodiverse planting, sunken gardens and sheltered external spaces help the home feel embedded within the hillside. These landscaped areas soften the building, support wildlife and create a more intimate relationship between interior and exterior spaces.
On an exposed coastal site, outdoor living must be carefully considered. Wide open terraces may offer views, but they can also become uncomfortable in wind. At Keynvor, sheltered courtyards and planted spaces create calmer microclimates, allowing the clients to enjoy the landscape in a more relaxed way.
The home does not simply look out at nature. It lives within it. This close relationship between architecture, landscape and setting is explored further in our article on designing contemporary coastal homes in Cornwall.
Sustainable design as part of modern luxury
For ARCO2, true luxury and sustainability are not separate ideas. A beautiful home should also be comfortable, efficient, healthy and future focused.
Keynvor was designed using a fabric first, Passivhaus inspired approach. Thick insulation, airtight construction, triple glazed windows, MVHR, an air source heat pump and renewable technologies help reduce energy demand while maintaining comfort throughout the year.
The completed home achieved an EPC rating of 100A and an air pressure test result of 1.44 m³/h·m²@50Pa. These performance outcomes demonstrate that high quality contemporary living can sit comfortably alongside low energy design.
For sustainable architects in Cornwall, this is an essential part of designing homes for the future. Comfort, beauty and environmental responsibility should work together.
A contemporary home designed for modern Cornwall living
Keynvor demonstrates how contemporary architecture can create a rich and highly personal living experience. The home is dramatic without being excessive, refined without feeling cold and sustainable without compromising comfort.
It captures the views across Mawgan Porth Bay, but it also creates privacy, shelter and calm. It offers generous open plan living, but also quiet rooms for retreat. It uses durable coastal materials, but with warmth and sensitivity.
This is the value of working with experienced North Cornwall architects. The best homes are not simply designed to look impressive. They are designed to feel deeply right for their site, their owners and the life that will unfold within them. This careful response to site, landscape and context is central to planning sensitive architecture in Cornwall.
