Shaped by site, climate, and craft — and built around the people who live in them.
Castillo Arquitectos designs distinctive homes that reflect both the individuality of our clients and the character of their surroundings. Whether nestled in nature or integrated into a community, our residences combine timeless design, refined detail, and lasting quality — every home tailored to elevate daily living.
The residential portfolio is curated: it represents the studio’s built work at its highest level of craft and specificity. Each house shown here responds to a particular site, a particular climate, and the particular lives of the people who inhabit it.
The houses below are custom residences in the Beach Town and El Prado neighbourhoods of Las Catalinas, each in dialogue with the community’s architectural language and expressing its own identity through colour, proportion, and detail.
Las Catalinas, Guanacaste, Costa Rica
Custom House · 360 m²
A single-family residence conceived as a direct response to its site and climate. Terraces, shade, and cross ventilation organize a daily life that unfolds between interior and exterior, in dialogue with the community’s coastal landscape. The soft coral-orange of its walls — the colour of a curuba fruit milkshake — gives the house its warmth and its name.

Las Catalinas, Guanacaste, Costa Rica
Custom House · 350 m²
A single-family residence that responds to the vegetation and topography of its immediate surroundings, with an architecture that favours shade, natural ventilation, and visual connection to the landscape. Its contrasting cream-and-brown palette references Guanacaste’s white-faced capuchin monkeys.

Custom House · 400 m²
A single-family residence designed from its particular siting, with spaces open to the exterior and a materiality meant to age with dignity within the community’s architectural language. Green — from the mint-tea colour of its walls to the vines in its private garden — is integral to this corner house arranged around a central courtyard.

Las Catalinas, Guanacaste, Costa Rica
Custom House · 400 m²
A single-family residence conceived as a response to its specific site, with terraces and outdoor spaces that extend domestic life toward the community’s coastal landscape. On a steep site in Beach Town, it rises as a gleaming white volume, its restrained facade giving it a quiet monumentality.
