Design Build and Design Assist

Making Your Vision A Reality

A home construction project can easily have many different companies and people working on the design and building. This includes designers, contractors, subcontractors, and sub-consultants– all of which can become costly if there isn’t sufficient and diligent oversight. This can cause stress and anxiety for homeowners who simply want to improve their living space.


Castillo’s Building Inc. is aware of the pitfalls of the traditional project delivery system that includes various middlemen to complete a project. Thankfully, our home improvement company has the capacity to maintain a streamlined project management system that eases the stress for homeowners. This includes managing all sub-consultants, subcontractors, and all parties involved in the building process.

There are many benefits to employing a design-build project management system for your home improvement build. Here are some of the benefits:

  • Integrated and united team
  • Owner only contracts one company for the project
  • Changes are addressed by Castillo’s Building and Plumbing
  • Efficient teamwork
  • More cost effective for homeowner
  • Less risk for homeowner


Castillo’s Building Inc. is also experienced in working in Design-Assist roles operating as subcontractors as well. While there are many Los Angeles-based home contractors, we consider our ability to integrate into a design and building structure very well. Our professionals collaborate at any point in the design process to plan the home improvement build accordingly. We assist architects and designers complete their projects on time.

Design assist is separate from design build almost entirely, but it’s another efficient way to get a project done efficient and with the utmost quality. Here are some of the benefits:

  • Streamlines the building process
  • Mitigates risk to architect
  • Gets contractors involved early on in the process
  • Enhances collaboration of parties
  • Allows architects to focus on design and less on construction
  • Property analysis and cost estimation

The property design management team at Castillo’s Building Inc. is committed to streamlining development processes to mitigate risks, maximize the use of funds, and deliver a perfect finished product to our clients.
