Construction, by us.

Astro Cósmico is the general-contracting arm of Astro Station. Custom builds, whole-home renovations and owner's representation — executed by our own team, under one contract, on the same drawings we drew.

A licensed GC inside the studio.

José Martínez

"The drawings move from our studio to our site without a translation step — because the people drawing them are the people building them. That is the entire point."

02 — Integration

Design → Build, under one roof.

Astro Cósmico does not exist in isolation. It is the construction phase of an integrated workflow that begins inside the architecture studio and ends with the keys turning. Every step lives under the same project manager.

01
Architecture
D. Castrillón

Schematic design, design development and construction documents. Drawing set sized to build, not to publish.

02
Interiors
M. Bernal

Space planning, finish specifications, FF&E sourcing, integrated joinery, install oversight.

03
Millwork · Dragon
In-house shop

Built-ins, kitchens, vanities, paneling — drawn, prototyped, fabricated and installed by our own team.

04
Construction
J. Martínez · GC

Site execution. Sub-trade management, daily logs, weekly reporting, quality and safety. Open-book budgeting throughout.

05
Handover
Studio

Walkthrough, commissioning, owner training, two-year structural warranty, lifetime referral support.

Each phase is led by the same principal who carries it. There are no handoffs between strangers. There is one project manager, one schedule of values, and one accountable signature: ours.
