I am a licensed, bonded, and insured General Contractor with an extensive background in design and construction. I do not just talk the talk, I walk the walk, having physically labored in trades ranging from tile and plumbing, to foundation and framing. To this day, there is seldom a project I will not roll up my sleeves for, be it setting lines for a home addition, or laying out complex tile patterns to be reproduced by my team. I received my Masters in Architecture (M.Arch) from UCLA, where I graduated with distinction. My commencement thesis focused on the California Accessory Dwelling Unit (ADU) legislation, a space that I have become a leading expert in. Building home additions and creating additional housing in the form of ADUs is my lifework: there is nothing more rewarding than delivering a finished project to a client. If you are contemplating a home addition, major renovation, or building an ADU, give me a call. I look forward to hearing from you.

"I recently hired Sklar Construction for a major renovation on my home in Culver City, and I was blown away by their service. From start to finish, they were professional, detailed, and truly cared about my project. The team was fantastic at keeping me updated every step of the way. They answered all my questions and made sure I felt comfortable with the progress. They finished the project on time, and the quality of their work was incredible. My home looks amazing, and I've gotten so many compliments on the renovation. What really stood out to me was how Sklar Construction listened to my ideas and offered great suggestions to make my vision even better. They were committed to delivering top-notch results, and it shows in every detail. I highly recommend Sklar Construction. If you need a renovation done right and want to work with a team that truly cares, go with them. You won't be disappointed!"

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

FAQs for addition to existing structure building service projects in Westminster, CA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
