HW Studio has crafted Casa Emma, a compact yet striking residence in Morelia, Mexico, centered around a pyramidal lightwell. Inspired by traditional Purépecha granaries and the architectural work of Eduardo Souto de Moura, this 54-square-meter home masterfully integrates light, space, and material to create a serene living environment.


Innovative Design on a Narrow Lot
Situated on a slender 4-meter by 10-meter lot, Casa Emma was designed as an excavation project, with a carved central void serving as its defining element. The home’s exterior features a minimalist chukum-coated facade, punctuated by a single shadowed window and a concealed entryway.
Upon entering, residents transition from a narrow chukum-plastered hallway into a spacious, wood-clad interior. The engineered wood walls evoke traditional granary construction while creating a warm and immersive atmosphere. According to HW Studio, the material change softens the space, making it feel light and almost floating.
Harnessing Light for a Transformative Experience
At the heart of Casa Emma lies a pyramidal skylight, allowing natural light to wash over the space. This feature draws inspiration from the Casa das Histórias Paula Rego museum in Portugal, where HW Studio’s team experienced the profound effect of light cascading down tall, enclosed interiors.
The skylight spans the width of the house, illuminating two flat longitudinal walls and two sloped transverse walls. Below, a lofted bedroom sits directly beneath the lightwell, shading the dining area while maintaining an open, airy feel.
Thoughtful Spatial Planning
Despite its compact footprint, Casa Emma maximizes functionality. The living area flows seamlessly into a partially lit kitchen with concealed utilities. A spiral staircase leads to the cantilevered sleeping space and bathroom, eventually opening onto a small rooftop patio formed by the sloped ceiling.
HW Studio’s innovative use of space, materials, and light ensures Casa Emma is more than just a home—it’s an architectural experience.
