Best Room Addition Contractor In San Jose, CA

Room Addition In San Jose

There are several ways you can add a new room to your home. No matter which one you decide to go with, we will listen to your needs and budget and plan for you the best options. 

Full Room Addition

A full room addition is a perfect way to add the space that you need and increase the square footage of your house. A room addition often involves expanding the home’s original footprint.

Whether you want to turn the unused vacant lot in your house into a guest bedroom, an ADU, an office, a den, a utility room, or want to create in your backyard, we can build the room you have envisioned from the ground up without breaking the bank.

Room Conversion

A room addition does not always have to start from scratch. If you have an unused garage or attic space in your house, a room conversion might be another way to go!

Utilizing your existing square footage is the easiest and least expensive way to add a new room since the foundation, roof, and walls are already in place. No matter you are planning to turn your unused lot into a kitchen, utility room, home gym room, or any other space, reach out to us, and we will make it happen.

Second Story Room Addition

A second-story room addition is another way to create a room you need without going beyond your existing square footage. To add a vertical room, your existing framing and foundations have to be structurally sound to withstand the additional weight.

Whether you want to build a room on top of your two or three-car garage or turn your upstairs attic into a living room, share the idea with us. Our team will assess the integrity of your existing structure, and if it is up to snuff, we will construct a room that you have visualized.

    Our Room Addition Process

    Our room addition process is simple and straightforward. We go to remarkable lengths to ensure the highest level of service quality at every phase of the project.

    Step 1 - Project Analysis

    Our consultants will conduct a site analysis to explore the possibility of the room addition and check whether the proposed addition meets the local building codes and zoning ordinances. We will then sit down with you to understand your needs and aspirations and provide you with the estimated costs and timeline of the project.

    Step 2 - City Permitting

    We will draw the required drawings and draft necessary documents, and submit them to the building authorities on your behalf to help you pull out the necessary permits for your room addition.

    Step 3 - Project Execution

    Once necessary permits are obtained, we will proceed to the actual construction. During this phase, our craftsmen will work closely with you to convert your idea into a fully functional, structurally sound, and aesthetically pleasing room that will seamlessly blend with the rest of the house, from both inside and outside.

    Step 4 - Project Close-Up

    Once your project is finished, we will perform a final walk-through to ensure that it has turned out exactly the way it was supposed to be and meets your unique needs.

    Step 5 - Post Work Clean-Up

    Following the completion of the project, we will thoroughly clean any dust and debris so that you can focus on things important in your life.
