Blue Bottle Coffee Sangenjaya Cafe

A fifty-year-old low building stands at the end of a dead-end lane between two larger blocks, a short walk from a railway station. From its doorstep the sky opens wide overhead, a rare sense of emptiness in a dense city.

It had been the home and clinic of the client’s grandfather, who also painted there in his later years. The site could easily have carried a new commercial or apartment building. Out of regard for him, the family chose to keep the house and make it a place for the neighbourhood rather than chase returns.

A first renovation created a residence upstairs and a gallery on the ground floor. The family then looked for a tenant, and a coffee company that shared their outlook opened a cafe in the remaining space.

The lane runs from a busy shopping street toward quiet houses and ends in a garden, an unexpected luxury so close to the centre. The cafe draws out that depth. Customers walk to the register at the far end, stop at the drip bar, pass through the seating, step out to the garden and then follow the building to the gallery entrance. Precast concrete paving traces the whole route, tying inside to outside and the building back to the street.

The original concrete, cast against cedar formwork, still shows the grain of the boards. Its rough surface reminded the coffee company’s founder of a musician’s idea of balancing roughness and softness, and the interior grew from that pairing: raw walls against clean steel counters and pale timber furniture.
