A second home should not be a scaled-down version of one’s main residence. When considering how to design a second home, the key question is not how many bedrooms it can accommodate, but what sort of life will unfold there. Summer days with the house full of guests, winter weekends, unexpected visitors, long periods of inactivity and a very specific relationship with the surrounding landscape all shape every decision.

In this type of project, designing less but better usually yields better results. A clear layout, materials that age gracefully and a cohesive atmosphere are more valuable than a mere accumulation of decorative elements. The house must feel like home from day one and function effortlessly for years to come.

Designing a second home based on actual use

A holiday home brings together activities which, in a main residence, are usually spread out over the course of the week. You cook for large groups, linger over meals, enter via the beach or the garden, work from home occasionally, and seek rest and relaxation. For this reason, communal areas tend to take precedence over private spaces.

Before finalising a plan, it is advisable to define scenarios for how the space will be used. Will the property usually accommodate a couple, a family with children or several groups of friends? Will it be used all year round or only in season? Will it be let out for certain periods? These answers determine the balance between the living room, kitchen, bedrooms, bathrooms and outdoor areas.

A coastal home for two-day getaways does not require the same logistics as a mountain home used for long holidays. In the first case, the home must be ready to move into immediately: accessible storage, a practical kitchen, simple climate control and minimal effort required to make it habitable. In the latter, it may be a priority to provide a larder, space for sports equipment, a place to dry clothes or a more cosy living area.

Flexibility also matters, though it should not be confused with cramming the house full of mechanisms. A bedroom that accommodates single beds or a double bed, a built-in bench that adds seating around the table, or sliding doors that connect and separate spaces solve real-life situations without complicating the architecture.

The location defines the space more than the views

Orientation, climate, slope, vegetation and privacy are all key design considerations. Views are valuable, but they are not enough to determine where a façade should open out. A large glazed area facing the sea can be spectacular and, at the same time, turn the living room into a space that is difficult to live in if the sun, wind or heat gain are not controlled.

In Barcelona and the surrounding area, the relationship between interior and exterior demands precision. A west-facing terrace may be excellent in winter but rather uncomfortable in August if shade is not incorporated from the outset. Porches, pergolas, shutters, louvres, integrated awnings or deciduous vegetation are not afterthoughts: they form part of the spatial and energy strategy.

It is also worth considering how one enters the home. The entrance must be able to accommodate sand, bicycles, suitcases, wet clothes or sports equipment when the context requires it. A small, well-designed entrance hall, a utility room or a cleaning cupboard can help keep the rest of the house tidy more effectively than an oversized living room.

Privacy deserves the same attention. A house open to the landscape need not be exposed to neighbours or passers-by. The positioning of windows, changes in level, courtyards and vegetation allow a view to be framed without sacrificing the sense of shelter.

How to design a second home with a well-thought-out layout

The best layout is not necessarily the most open-plan. Open-plan spaces work well when their proportions, circulation routes and utility areas are carefully thought out. If the kitchen, dining room and living room share a single space, each activity must retain its own area without competing for space, noise levels or storage.

A good rule of thumb is to place the most frequently used spaces where the house receives the most light and has a direct connection to the outdoors. Rest areas can occupy more sheltered spaces, with acoustic and thermal control. This hierarchy is particularly useful in refurbishments, where it is not always possible to alter the structure but it is possible to redefine the experience of each room.

Storage should be designed as architecture. In a second home, it allows for the storage of seasonal textiles, tableware for larger groups, games, beach or mountain gear, and personal belongings when the property is shared or let. Incorporating bespoke cupboards, benches with internal storage, or generous kitchen units prevents the house from feeling makeshift or cluttered.

Bathrooms also reveal whether a design has properly understood their intended use. A very small bathroom may be sufficient for a couple, but it becomes a bottleneck in a house designed for eight people. Sometimes, adding an extra toilet or separating the washbasin, shower and toilet has a greater impact on day-to-day life than extending the living room by a few metres.

Materials for living, not just for photography

The identity of a second home is built on a limited palette that relates well to its surroundings. Stone, timber, ceramics, mineral mortars or natural textiles can lend character without turning the house into a literal interpretation of the local style. The aim is for the materials to provide texture, scale and continuity.

The choice must take maintenance into account. A highly porous surface next to a swimming pool, unsuitable timber on an exposed façade or delicate flooring in a home with children may require a level of care that is incompatible with the frequency of use. This does not mean you have to choose impersonal solutions. It means you must specify carefully.

The most durable materials are not always the most suitable, because durability has various meanings: withstanding damp, tolerating knocks, ageing well in the sun, being easy to clean and being repairable. A continuous ceramic floor can provide a calm and practical base; well-treated timber can add warmth to relaxation areas. The combination depends on the location, the budget and the level of maintenance the owner is prepared to undertake.

Lighting should follow the same logic. During the day, the house needs controlled natural light. At night, it needs layers of light: discreet general lighting, task lighting over tables and worktops, and ambient lighting that makes a terrace or living room liveable without making them feel cold or uninviting. Warm, dimmable lighting is usually a wise choice, provided the installation is planned before deciding on finishes and furniture.

Designing for periods of absence

A second home spends time unoccupied. This fact affects security, the building services and the finishes. Climate control must be manageable efficiently, ventilation must prevent damp, and water systems require safe solutions for periods when the property is unoccupied. These are not trivial decisions: they determine comfort and costs throughout the property’s entire lifespan.

Home automation can add value if it tackles specific tasks, such as controlling blinds, climate control, outdoor lighting or leak detection. It makes no sense to incorporate technology simply for the sake of it. A house must be easy to use for owners, guests and maintenance staff, even when the connection fails or the user changes.

In comprehensive refurbishments, it is common for these items to be considered late in the process, when the budget has already been tied up in visible finishes. It is an understandable mistake. Allocating resources to insulation, joinery, shading, installations and storage usually enhances the experience more than increasing the cost of a purely decorative finish.

An investment with its own identity

If the property is to be used partly for letting, it should be designed to withstand a reasonable turnover of tenants without losing its character. The key is not to make it neutral, but to create a design language that is clear, durable and easy to maintain. A good design produces attractive photographs, but also offers intuitive layouts, adequate facilities and details that make a stay comfortable.

At FFWD Arquitectos, we view a second home as a holistic experience: architecture, interior design, light, materials and everyday use must all respond to a single vision. This coherence prevents the house from being perceived as a succession of isolated decisions.

The best second home does not try to impress with every square metre. It knows where to open up, where to offer shelter and which needs to anticipate. When the project truly understands those who live there and the surrounding environment, arriving ceases to be a mere journey and becomes, at last, a way of being.
