What should a coastal home feel like?

For this project, the answer was not simply a house with a view. The ambition was to create a relaxed, characterful and enduring family home—one that responds to its coastal setting while providing the comfort, flexibility and energy performance expected from a contemporary new-build property.

The resulting proposal draws inspiration from traditional New England coastal architecture, reinterpreted for modern life in Cornwall. Familiar forms, natural materials and carefully considered proportions are combined with an open, light-filled interior designed around the way the owners want to live.

It is a project that balances character with performance, openness with privacy, and architectural ambition with the sensitivities of designing a replacement dwelling in a highly valued landscape.

A Home Shaped by Its Setting

Successful coastal home design begins with understanding the site.

Rather than treating the landscape as a backdrop, the design has been developed in response to its orientation, changing levels, approach and long-distance outlook. The position and form of the proposed dwelling have been carefully considered to make the most of natural light and views while respecting the wider character of the area.

The proposal replaces an existing property with a home that is better suited to its setting and to contemporary family life. Its architecture is deliberately composed as a series of connected forms rather than a single imposing volume, helping to break down the overall scale of the building.

This approach creates a more relaxed, domestic character while allowing different parts of the house to respond individually to the landscape.

A Contemporary Interpretation of New England Style

The clients were drawn to the understated elegance of New England-style homes: pitched roofs, strong gable forms, balanced elevations, generous windows and a material palette that becomes more attractive as it weathers.

Rather than reproducing a traditional American coastal house, the design takes these recognisable principles and gives them a distinctly contemporary interpretation.

A clear central form establishes the identity of the house, while lower wings and connecting elements reduce its apparent mass. Carefully positioned gables create rhythm across the elevations and help frame important views from within the building.

Slate roofing provides a natural connection with the architectural character of Cornwall, while limited areas of metalwork introduce a crisp, contemporary detail to canopies and secondary elements. External materials have been chosen for their durability, visual warmth and ability to weather naturally in a coastal environment.

The result is a contemporary coastal house that feels familiar without becoming pastiche: traditional in influence, but modern in its construction, detailing and performance.

Turning Traditional Living Upside Down

One of the defining features of the design is its upside-down living arrangement.

In a conventional house, the principal living spaces are normally located at ground-floor level. On a coastal site, however, this can mean that the best views, daylight and sense of openness are reserved for bedrooms or circulation spaces.

Here, the arrangement has been reversed.

Private rooms are positioned on the lower level, creating calm and sheltered spaces for rest. The principal kitchen, dining and living areas are placed above, where they can benefit from a broader outlook, improved natural light and direct connections to external terraces.

This upper floor becomes the social heart of the home.

The kitchen, dining and living spaces are brought together as a generous open-plan environment, but each area retains its own sense of identity. Carefully considered changes in orientation, ceiling form and furniture arrangement allow the rooms to feel connected without becoming one undifferentiated space.

Large areas of glazing strengthen the relationship between inside and outside, while sheltered terraces extend the living areas during warmer weather. Throughout the year, the elevated position creates a changing backdrop of sky, landscape and coastal light.

Designed Around Everyday Life

Although the setting is exceptional, the success of the house will ultimately depend on how well it supports everyday life.

The internal layout has therefore been developed around the routines and priorities of the people who will live there. Arrival, storage, cooking, entertaining, working from home and quieter moments have all helped shape the plan.

The principal bedroom suite is designed as a private retreat rather than simply a place to sleep. Family and guest accommodation is arranged to provide both independence and connection, while flexible rooms allow the house to adapt to changing needs over time.

Dedicated spaces for home working, exercise, relaxation and entertainment are integrated into the wider layout. These rooms are not treated as leftover additions; they form part of a broader approach to creating a bespoke family home capable of supporting different activities throughout the day.

An ancillary building provides further flexibility, offering opportunities for guest accommodation, creative work or independent family use without compromising the privacy of the main dwelling.

This is one of the central benefits of a carefully considered bespoke house design: the building is developed around the client’s life rather than asking the client to adapt to a standard layout.

A Calm and Durable Material Palette

Homes in exposed coastal environments require a thoughtful approach to materials and detailing.

For this project, the palette has been deliberately kept simple. Natural textures, muted colours and robust finishes will allow the architecture to sit comfortably within its surroundings while reducing unnecessary maintenance.

The use of slate, timber-inspired finishes, painted surfaces, stone and restrained metal detailing creates a sense of warmth without competing with the landscape. Materials are intended to develop character over time rather than relying on finishes that only look their best when newly installed.

Inside, the same principles continue.

Natural finishes and carefully framed views will provide the visual interest, allowing the interior architecture to remain calm and uncluttered. The intention is to create a relaxed coastal home rather than an overly polished showpiece—a place that feels comfortable throughout the seasons and becomes more personal with use.

Balancing Ambition with Planning Sensitivity

Designing a replacement dwelling in Cornwall often involves more than producing an attractive house.

The relationship between the building and the landscape, neighbouring properties, existing development patterns and public views must all be considered. This becomes particularly important within sensitive coastal areas and protected landscapes.

From the earliest design stages, the scale, width, height and composition of the proposal have been assessed as part of the overall planning strategy. Breaking the building into a hierarchy of forms helps reduce its visual impact, while the roofscape and material palette establish a connection with the area’s architectural character.

The proposal has also been developed with careful consideration of neighbouring outlook and the experience of approaching and passing the site. Landscape design, boundary treatments and external works will help integrate the building into its setting as planting matures.

This collaborative process between architectural design, planning and landscape considerations is essential. Rather than developing a design in isolation and attempting to justify it afterwards, each element informs the others from the outset.

Sustainability Without Unnecessary Complexity

Energy efficiency is a fundamental part of the proposal, but the approach is intentionally practical.

The first priority is to create a building envelope that performs well. High levels of insulation, good airtightness, carefully designed junctions and high-performance windows will reduce heat loss and improve comfort throughout the year.

The orientation and internal arrangement allow principal rooms to benefit from natural light, while considered glazing and shading will help manage changing conditions through the seasons. Durable materials and straightforward construction methods will also contribute to the long-term sustainability of the building.

Mechanical systems can then be selected to complement this fabric-first approach rather than compensate for weaknesses in the building itself.

For the clients, the objective is not to fill the house with unnecessary technology. It is to create an energy-efficient coastal home that is comfortable, economical to operate and simple to maintain.

Creating a Home with a Sense of Belonging

The most successful new homes do more than meet a brief.

They feel as though they belong—to their owners, to their landscape and to the particular conditions of their site.

This proposal is shaped by a clear architectural idea, but it is equally shaped by practical decisions: where morning light enters the house, how people arrive after a walk, where guests gather, how quieter spaces are separated and how the building responds to changes in weather.

By combining New England-inspired architecture, contemporary construction and a detailed understanding of coastal living, the design aims to create a home that feels both distinctive and settled.

It will be a modern family house with the relaxed character of a traditional coastal home: generous without being ostentatious, carefully detailed without feeling precious, and designed to become more established as the building and landscape mature together.
