Develop Your Custom Home From the Ground Up
A custom home starts with more than a list of rooms. How you enter the property, move through the home, gather with family, and use outdoor space can all influence the design. XactBuilt helps you bring those priorities into the planning conversation alongside the characteristics of the site.
We can discuss room arrangements, natural light, storage, exterior style, and the materials you want to use. Those decisions should be considered with the proposed construction scope and budget priorities. If you already have drawings, they can help establish a starting point for discussing the work.
New home construction involves coordinating the site, building plans, utility needs, permitting, and the construction itself. Our design-build approach connects these parts of the project so the home can be developed as a complete proposal. Site conditions and project requirements influence the scope, so the first conversation should focus on your specific property.
Based in Whittier and led by Sergio Murillo, XactBuilt Construction Inc. serves nearby Los Angeles County communities, Pasadena, and selected Orange County markets. Share your property location, existing plans, and the home you want to create. We’ll follow up to discuss the project and the next steps toward an estimate.

A garage conversion may be an option for creating a separate living space with a kitchen and bathroom. Feasibility depends on the existing structure, utility connections, property conditions, and applicable requirements. XactBuilt can help you explore the design, permitting, and construction involved.
An accessory dwelling unit, or ADU, provides independent living facilities, including cooking and bathroom facilities. A room addition expands your existing home, such as adding a bedroom or enlarging a living area. The right choice depends on how you want to use the space and what your property can accommodate.
Pricing depends on the project’s size, existing conditions, design, materials, utility needs, and construction scope.
