Our Client Testimonials
Adding a second story addition to our Santa Clara home felt risky until we signed with Lecut. They locked in our contract price before breaking ground, eliminating cost overruns. Their crew worked efficiently, completing structural framing ahead of schedule while keeping the job site spotless.
Our rotting porch in Palo Alto was unsafe, but Lecut completed a new composite deck building job in four days flat.
We had a great experience working with Lecut and Yari on our bathroom remodel. Yari was very responsive and easy to communicate with throughout the entire project, and Lecut did a great job with the installation and finishing work.
They were professional, reliable, and always willing to come back and take care of small details when needed. We're very happy with how everything turned out and really appreciate their hard work and attention to detail.
I had a consultation with Yari to discuss a potential home remodel. He spent a great deal of time understanding my goals, brainstorming different layout options, and explaining the pros and cons of each approach. I appreciated that he was thoughtful, patient, and transparent throughout the discussion. He followed up with a detailed summary of our meeting and a realistic preliminary estimate, which helped me make an informed decision. Although I ultimately decided not to move forward with a major remodel, I had a very positive experience working with him and would gladly recommend him to anyone looking for a knowledgeable and professional contractor.
LeCut will ensure you love your renewed home.
After beating out two other remodel bids, because of the team, vision, and value, Yari, Luis, and team transformed our outdated bathroom into a clean, usable, and comfortable space. Working with Yari was a great experience, since he personally ensured we were 100% satisfied with the results of the project. Communicating with the team was smooth and the team was clean and respectful with with the rest of our house. Prior to completing the project, Yari did a thorough inspection with us to identify issues with tile alignment and grout finish. Yari and Luis brought the team back to rework the fit and finish items quickly, leaving us completely happy with the space.
We needed a kitchen update and a complete bathroom renovation in a smaller home. They maximized the space without making it feel crowded. Cabinets, counters, and tile all look custom. Communication was clear from start to finish and there were no last-minute extras. The rooms feel new and well built.
We remodeled the kitchen and two bathrooms as part of a larger first-floor refresh. The kitchen now works for a family and the bathrooms feel like they belong in a nicer house. Attention to trim, grout, and hardware stood out. They stayed on schedule and the final walkthrough was thorough. Extremely pleased with the results.
Our master bathroom and kitchen were last remodeled in the 90s, so we finally hired LeCut. The walk-in shower, dual vanity, and new kitchen layout completely changed how we use the house. Our project manager was on site almost every day and handled the permits without us lifting a finger. Workmanship is excellent and they finished a week early. Couldn’t be happier with LeCut!!!
We couldn't be happier with our experience working with LeCut Construction. Yari, Luis and the whole team were great to work with throughout the process. They responded quickly to every question, concern or comment we had every step of the way. They completely remodeled both our bathrooms and we love how they both turned out.
Lecut Construction completed a full remodel of our kitchen and master bathroom plus beautification of our garage. Yari Bardugo presided over the operation with skill, attentiveness, and good humor. All structural work was totally robust – we could see the quality being built in. Work on the finish elements was where Yari really shined. He checked for our desired positioning of lights and switches and the height of grab bars. When we were uncertain, he offered helpful suggestions. Yari also orchestrated various resources within Lecut (electricians and tilers) and outside (asbestos removal and HVAC). If anything wasn’t perfect the first time, Yari helped us improve it. He came to visit nearly every day, and we enjoyed our conversations very much.
Sunnyvale is also characterized by its serene residential streets adjoining the Heritage District, the historic Murphy Avenue, and family-centered neighborhoods of the area surrounding Ortega Park, and residential homes that are based on the antique California ranch designs in combination with contemporary Silicon Valley changes. Our team comes up with room additions that do not interfere with this local character but a natural expansion of the homes in an intelligent manner. We know that additions in Sunnyvale have to be integrated in the old neighborhoods where function and harmony are important.
The local climate conditions heavily determine the way we treat design and construction. During winter seasons, Sunnyvale has hot, dry summers, mild humidity and cooler nights. Our staff intends to add rooms that are heat resistant, well insulated and air conditioned. Addressing these environmental factors at the initial stage of the process, we will make new spaces comfortable, energy-saving and durable all year round.
Custom Home Additions for Growing Families
There is a tendency to increase families that require more space that facilitates the transition of routines and long-term plans. Our team believes in the development of a tailor-made room addition that enriches the daily living and falls within the climate and styles of housing that are in line with the Sunnyvale climate.
Family-Focused Space Planning
We start by knowing how the existing space is utilized by households and where they will be most affected in case of expansion. The layouts are developed in such a way that they facilitate movement, storage, and natural lighting. Another thing we do is to expose ourselves to the sun in order to cool the heat.
Materials Chosen for Comfort
During hot seasons of summer, Sunnyvale has hot weather that needs materials that can cope with the heat. We choose the insulation, finishes and structural materials that stabilize the interior temperatures. These options can be used to save on cooling and enhance comfort. Each selection is informed by performance and durability.
Adaptable Living Environments
Our designs enable the rooms to develop as the family needs change. The space can facilitate work, rest or development. We incorporate extensions that do not interfere with the general flow of the house. The outcome is deliberate and pliable.

We Build Additions That Match Your Home’s Character
Each house has a unique identity and our group of personnel strives to maintain it. The architectural features, roofs, and facades are studied to inform the design. This will enable the newcomers to harmonize with the structure.
The important aspects that we pay attention to are:
- Roof and exterior correspondence with the original home.
- Smooth and purposeful interior transitions.
- Local climatic insulation and ventilation.
- Things that wear well in the climate of Sunnyvale.
With the coordination of such details, we do not create the impression of an add-on. The completed space is seamless and integrated. We aim to improve the home and not to change its character.
Room Expansion Services That Maximize Comfort
A major objective of each room expansion that we do is comfort. Our team comes up with additions that ensure equal temperatures inside the building even in the long and hot summer months in Sunnyvale. We devote our attention to the level of insulation, the arrangement of airflow, and the orientation of rooms to minimize heat accumulation and eliminate hot spots.
We also pay a keen attention to incorporations of natural light in every addition. Placing strategic window position and shading methods can enable the daylight to maximize the space without promoting more heat indoors. This equilibrium makes rooms light and spacious. With a blend of climate conscious planning and considerate design, we are able to serve our room expansions that enable comfort throughout the year in everyday living.
Expand Your Living Space Thoughtfully
The home additions must be safe and long lasting and this entails structural integrity. Our team will start by critically assessing the current structure such as foundations, framing and load paths. This test will make sure that the new space will be supported adequately by the home without affecting the stability.
We also consider the material movement due to the warm days and cool nights in Sunnyvale. Unless well planned, temperature variations may cause stress to the building elements. We use construction techniques that enable materials to expand and contract on their own and be strong. With engineering and craftsmanship, we create the additions that are solid, secure and constructed to last.
Carefully Extend Your Living Area
Home expansion in Sunnyvale ought to be a well-planned and satisfactory experience. Our team will add climate awareness, structural care, and considerate design to each addition of the room.
Reach out to us and start thinking about creating a space that would be helpful to your family and that would also seem a natural extension of your home.

For a 20x20 room addition, homeowners in San Jose, Santa Clara, and Sunnyvale should expect costs to vary widely based on materials, foundation work, and permits. A basic shell might start around $40,000 to $60,000, while a fully finished space with electrical, plumbing, and HVAC can range from $80,000 to $120,000 or more. High-end finishes or complex structural changes will increase this figure. It is critical to obtain multiple detailed bids from licensed contractors.

Lecut Construction advises that site conditions and local code requirements in Santa Clara County significantly impact final pricing.
The cost to add a 12x12 room onto a house in the San Jose area typically ranges from $30,000 to $60,000. This wide range depends on factors like foundation type, roofing, electrical, plumbing, and finishes. For a basic shell addition, expect lower costs, while a fully finished room with HVAC and custom features will be at the higher end. Permits and engineering fees in Santa Clara County also add significant expense. For a detailed breakdown of these variables, please refer to our internal article Room Addition. At Lecut Construction, we always recommend getting a site-specific estimate, as soil conditions and existing structure can greatly affect the final price.
The 30% rule for renovations is a financial guideline suggesting that homeowners should not spend more than 30% of their home's current market value on a single renovation project. This principle helps ensure that the cost of improvements does not exceed the value they add to the property, preventing overcapitalization. For example, if your home is valued at $500,000, you should limit a renovation budget to $150,000. This rule is particularly relevant when considering major kitchen or bathroom remodels. At Lecut Construction, we advise clients to carefully evaluate their home's value before starting a project. For more specific guidance on local regulations and budgeting, we recommend reading our internal article titled San Jose Home Remodeling Permits: The Complete 2026 Guide for Homeowners.
