Our Client Testimonials
They completed the project efficiently while maintaining high standards of quality and professionalism. The team paid attention to every detail and made sure we were satisfied with the results. I would definitely hire them again.
We finally brought down our master bathroom and started from scratch. The old layout had the toilet right next to the tub which was just weird. LeCut crew helped us rearrange everything so the space actually makes sense now. The shower is bigger, the vanity has actual storage, and the whole room feels like a mini spa. If I ever need some remodeling done right in San Jose, I know who to call
They handled my remodeling project with great care and kept the workspace clean every day. I appreciated their honesty, professionalism, and dedication to delivering high-quality results. I would definitely recommend them for any construction or renovation needs.
I was nervous about renovating our tiny San Jose bathroom, but LeCut delivered beyond expectations. They maximized every inch of space, added beautiful tile work, and finished a full week early. The crew was professional, cleaned up daily, and even helped us select fixtures that fit our budget.
We turned our cramped, dark basement into a bright family room and a guest bathroom. It was a big project, but the remodel contractor walked us through every decision. The space is so cozy now that we actually fight over who gets to hang out down there. It’s not just extra square footage, it’s become our favorite room in the house. Such a smart use of space.
My Mom had been wanting to remodel our kitchen for quite a while but after a bad experience with a different contractor our family was very nervous about starting the work back up. Guy with LeCut helped reassure us from the first consultation all the way through till the completion of the project. We really appreciated his transparency and clarity whenever we had questions.
Tal and Nir gave us a first class design experience, looking at Mom's inspiratons and working with us to nail down all the details like paint, materials, lighting, etc. Their full 3D renders got us really excited about the project, and being able to see exactly what the finished product would look like before construction began gave us a lot of confidence.
Sammy and the build team were fantastic. They finished everything from demo, paint, flooring, cabinets, countertops and more in just a month! They worked with Guy to flag and correct any issues quickly. From craftsmanship to making sure everything was up to building code requirements, their work speaks for itself - our family loves how gorgeous our house is now!
LeCut Construction gave us as stress free a remodel as I think you can get with stunning results. Really appreciate Guy and his whole team for their efforts, and would recommend them looking to do remodel work.
Experienced team creating clean finishes and delivering steady updates.
I recently found myself locked out of my house late at night, and it was a terrible experience. I called an emergency locksmith, and a technician came to my location in an incredibly short period of time, less than 20 minutes. He was very professional and polite. He quickly unlocked me into my house without causing any damage. The service was excellent, and the charges were reasonable for the emergency.
Working with this business for our bathroom remodel was a smooth experience. They listened to our ideas and offered custom home remodeling suggestions that fit perfectly. The end result feels really professional without feeling overdone.
My home addition fits so naturally that visitors think it was originally built that way. Their design ideas helped us avoid a lot of guesswork. I am really happy with how the project turned out.
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.
Architectural services
We provide complete remodeling solutions tailored to your needs. Our team focuses on quality, detail, and creating spaces that truly feel like home.
Dedicated to excellence in every project we deliver. From concept to completion, we build spaces that reflect your vision and lifestyle.

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.

The cost to add a 12x12 room onto a house in the San Jose area typically ranges from $30,000 to $60,000.

For a basic shell addition, expect lower costs, while a fully finished room with HVAC and custom features will be at the higher end.

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.
