1245 Pearl St., Boulder, CO, 80302

Skycastle Construction approaches design and construction by looking at the bigger picture. It studies the site and its opportunities, considering energy, natural resources, and sustainability in every phase of the decision-making process. The firm has developed a process that makes the project as predictable, reliable, and enjoyable as possible.

The process starts with the first conversation between the team and clients. After the clients sign the contracts for pre-construction and design, the firm proceeds with initial estimates, design development, engineering, further specifications, and material ordering. The firm creates a detailed set of drawings and final construction documents, and applies for a building permit. It also handles the construction management and the project closeout. 

Thanks to the success of this process, Skycastle Construction was once again hired for the remodeling and expansion of the original Japango Sushi restaurant it designed in 1999. The remodeling incorporated a modern twist on traditional concepts for the space by adding cozy seating areas, a new Pearl Street façade, dynamic lighting, a cylindrical jellyfish tank, and creative finishes inspired by the Japanese sake box.
