Average rating: 5 out of 5 stars25 March 2018
“After 5 years of saving, I finally decided to remodel my home. I had to have my master bathroom done a specific way, because I've always had a vision of "the perfect bathroom". I called Progressive Builders see what they had to offer. They gave me a very reasonable estimate for what I asked for. They also answered my all questions and gave me no hassle at all. I wish that more companies were like this. They were very patient with my every request. It was a pleasure working with Progressive Builders. I'd highly recommend them for any remodeling needs because they have what it takes to satisfy their customers. My master bath is beautiful thanks to them.”

Average rating: 5 out of 5 stars20 October 2021
“So pleased with my new shower from Platinum Home Builders & Design! The process was so quick; I had my dream shower installed in A Few days ! I didn't think that was possible - I had the same shower tiled in '08 and it took nearly a month to install. I couldn't take looking at the moldy walls any longer - no matter how hard I cleaned nothing helped. I am so thankful for the Microban feature; it keeps my shower clean and keeps me protected. Everyone I spoke with/interacted with was so friendly - this experience was a true pleasure. Thank you, Platinum”

Average rating: 5 out of 5 stars29 April 2015
“SK Home Designz was fantastic! We hired them to replace our glass backsplash in our kitchen with white mosaic tile. Steve helped us every step of the way, He did an in person consultation and gave us a very affordable and fair estimate for the job and agreed to take it on, even though it was a smaller job than usual. The work was done in a timely manner-- only three days-- and we were really happy with the results. We definitely recommend them and would hire them again.”
US Home Developers Inc.
House Extension Professionals in Simi Valley, CA
Average rating: 5 out of 5 stars3 July 2014
“My family and I pooled our money together to get me a new condominium in Reseda, CA. We got it for an incredibly good price, but it needed extensive remodeling work. I needed to remove the carpet and replace it with wooden tiles, re-paint the entire place, fix up the wiring, and the plumbing and I needed to redo the entire bathroom. It was no easy matter. What was even more problematic was that the current house I was living in is being foreclosed on and I had roughly 3 months to move out. My step mom knew about US Home Developers through a friend of hers who hired the company before, so she pressured me to look into them. I was sort of new to the whole experience but US Home Developers made it extremely easy. They were up front about the cost and time estimates, and were willing to work with me to provide the best solutions for the limited budget I had. Every day I would come to the condo after work and see what has progressed. I was constantly amazed at the speed by which everything was taken care of. The bathroom was the longest and hardest part because of all the necessary plumbing. They redid the tiles in the kitchen, and replaced all the carpets with the hardwood flooring that I wanted. They actually ended up finishing 2 weeks earlier than I had to move out and I was thrilled because it game a lot of time to move in and get settled. As someone who was entirely new to the experience of having a remodeling job done, I was really amazed at how easy, and great US Home Developers has made the experience.”

Hybrid Construction

Average rating: 5 out of 5 stars26 May 2021
“I have had the pleasure of working with Hybrid Construction on multiple home improvement projects as well as remodels. Whether the project is large in size or small they are always friendly and professional. They offer design recommendations and suggestions as well as preforming the actual work to get the job done. The owner is always responsive to my many questions and takes the time to explain the pros and cons of the various options that are presented to me for my project. When you hire Hybrid Construction for your project you can be assured that the owner will be on the job site on daily basis, not just at the time that you sign the contract. As we all know, this is not always the case w/ General Construction companies. This is 1 major differentiator in my opinion, between Hybrid and other companies. I have been living and working from my home while construction is being preformed. I truly appreciate Hybrid Construction's attention to detail in both the creative space as well as the day to day cleanliness of the job site. To know that my home will be left neat and tidy and the end of the working day is a relief! Hybrid Construction represents a team of honest, reliable, creative and hard working individuals. I receive frequent compliments on my home and yard all based on the work preformed by Hybrid Construction!”

Builder FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Simi Valley.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
