Building a home is one of the most rewarding yet challenging journeys in life. If you are looking to start this journey make sure you bring along Alleanza Custom Homes because they will make it an amazing experience. We spent months looking for a building company but when we met Shawn and the team at Alleanza we knew it was a good fit. After completing our home I can without hesitation say that it was 100% the right decision. Shawn has the perfect mix of experience, talent, and customer service. From the very beginning to the very end he was helpful and involved. He took our desires and tried his very best to make sure they were met. All while staying within budget! I would be remiss to not mention the rest of the amazing team at Alleanza. Carlos provides great attention to detail and planning by making sure things go smooth during construction at our home. Belly works in the background to make sure finances and selections are taken care of. They both are an essential piece to the company. If you are looking to build a home there is nobody better than Shawn and the team at Alleanza. We are very happy with our home and can not recommend Alleanza Custom Homes enough.Read More

It is with great enthusiasm that we endorse Alleanza Custom Homes, Shawn Sidoti and his team. After our home was flooded by hurricane Harvey in August of 2017, we found ourselves in immediate need of major repairs and renovations. In the midst of labor shortages and home builder pricing skyrocketing, Shawn proved to be the calm in the eye of the storm, presenting a clear path to recovery and at a very fair price. It was quickly obvious that he absolutely knows his trade, which we also confirmed directly with prior clients. And of utmost importance, Shawn’s integrity, communication and follow-through was vastly superior to any other builder we have dealt with in the past 30 years. As with all fast-track projects, multiple design changes and construction change orders come with the territory. And these are the homeowner’s biggest fear. In every instance, Shawn provided valuable analysis, alternative solutions, sensitivity to budget and sound counsel on the optimal solution. As a result, we fully understood the options and pricing needs. At no time did we ever feel we we’re being taken advantage of nor our trust abused. In short, we would hire Shawn again in heartbeat. To that end, we are already doing so for upstairs renovations. We readily refer Shawn to our friends and neighbors without hesitation.Read More

Flooding is not for sissys! Hurricane Harvey unexpectedly flooded our house and we were set on the daunting task of gutting our entire floor first, finding a builder and rebuilding. Thousands of other Houstonians were doing the same thing. Luckily we found Alleanza Custom Homes. The team at Alleanza, namely Shawn and Steve, made that nightmare of a year much more bearable. They were professional, patient and kind hearted. Every crew did a phenomenal job. Steve went above and beyond on many occasions to make sure things went smoothly. I would highly recommend Alleanza.Read More

3 years on and still providing excellent service. I built a house with Shawn in 2015 and recently wanted to make a few updates - beadbord ceiling, new custom shelves, new gutters, etc. Shawn and his foreman Carlos did an excellent job as usual. I will definitely be using Alleanza for my next home.Read More

Building a home for a licensed home inspector and my wife, who is a Realtor, would have to be one of the most challenging projects for any builder. Shawn and his team, Carlos and Belly, were great to work with from start to finish. The home building process involves so many decisions. Shawn was very supportative and involved which helped us immensely. It also creates many challenges which Shawn met head-on and resolved. Our project was completed on time and on budget. I would highly recommend Alleanza Custom Homes.Read More

We built our dream 4,000+ sq ft custom home (modern/transitional) with Alleanza in Oak Forest in 2017. Shawn and his team - special shout out to Carlos - were an absolute pleasure to work with throughout the planning, construction and post move in phase. During the planning stages, they were able to take take our vision and give us crucial advice to realize this vision while sticking to our budget. Building a custom home can be quite complex and stressful, but throughout the construction Shawn was able to make the small decisions for us, while finding the right times to get our inputs. He's only able to do that because he truly gets to know the family moving into the home - something just isn't there with the some of the more cookie cutter custom homes that get built in Houston. He and his team were always accessible and super easy to communicate with. Finally, I would add that during our search for a builder (which was quite vigorous) Alleanza is one of the few home builders that could build any style of home - from contemporary, to craftsman, tuscan, etc. When looking at their previous projects, you can tell that they've pretty much "been there, done that" with all styles of homes you could think up. Our family couldn't be happier and love living in our new home (which we moved into 3 months ago)!Read More

Alleanza Custom Homes did all the repairs to my home after the Hurricane Harvey flood destroyed it. Every facet of reconstruction was completed in an extremely professional manner with a high degree of attention to detail. The crews doing the work (drywall, painting, cabinets, electrical, etc) have been working with Alleanza for a long period of time. They were not "fly by night" crews picked up at a local Home Depot. Therefore, the quality of their work was based upon years of experience and training. Steve, a reconstruction Supervisor was assigned to my home. He was always available for any issues or problems that naturally arise during a reconstruction project. I heartily recommend Alleanza Custom Homes for any construction needs. I am also available to personally discuss their work ethics and quality on a "face to face" conversation and open my home for your inspection.Read More

Shawn and the Alleanza team helped us rebuild and renovate our home after Hurricane Harvey. They were extremely honest, professional, always reachable, and made it a priority that we would be happy with the final product. All of their subcontractors were very skilled. We were done without any major delays and as they had estimated. Alleanza turned an extremely stressful situation into a positive experience. We’re grateful, and would recommend Shawn and his company to friends and family.Read More

My wife and I had a great experience building with Alleanza Custom Homes and we highly recommend Shawn and his team. It doesn’t get much better than ‘On Time and Under Budget’! I found Alleanza to be right-sized for handling several custom projects at once, but not so big to get overextended with too many crews/superintendents where the personal touches are lost. Alleanza repeatedly uses its stable of quality subcontractors and one of Shawn’s strengths is assigning the right contractor to each job based on type of materials, style, cost, timing, etc. We were very pleased with the attention and communication that Carlos provided as the primary superintendent overseeing the work. I was much more hands-on than most homeowners and Alleanza accommodated my involvement and managed expectations. Shawn and Carlos also went above and beyond helping to coordinate tasks on our neighboring property to ensure that our overall vision for the project was accomplished. Lastly, a difference maker was Shawn’s team behind the scenes, particularly Belly, who managed costs and amazed us by procuring our selected items—from plumbing and lighting fixtures, to mechanical components and appliances—at prices that had a huge impact reducing the bottom line. Overall, we would not hesitate to recommend Alleanza to help you achieve your custom dream house. See photos at More

One year into trying to find our perfect home we decided to look into building custom. Shawn was referred to us from a friend and we also met him at one of his previous open houses. Shawn spent over one year with us trying to find the perfect lot. He went out of his way and visited multiple lots with us until we ultimately agreed on one that fit our budget, location and size requirements. Once we selected the lot Shawn referred us to Allen Irvin, his ‘go-to’ architect. Al and Shawn have established a very good working relationship and stewarded us through our first custom house build. During the House build Shawn never missed a beat, he guided us through the process and assisted us in our decision making when we were having trouble. My wife and I selected Shawn because we felt we had a lot in common with him, including small children. On a number of occasions during the build Shawn was forthright and honest in providing us opinion on key aspects of building a “kid friendly” home with a large mud room, master bedroom upstairs, segregated granny suite, an extensive series of custom built-in cabinetry as well as an outdoor space that extended the entertainment area in the interior of the house. Shaun was extremely attentive and accommodating to us as first time home builders set on designing the ‘perfect house’ including daily site walk through, frequent calls on interior design issues and ideas including design of specialized crown molding and custom cabinetry stains. Shaun and his team were able to react quickly to small changes throughout the build process including dog accommodations, custom waterfall island design and a custom table for our kitchen nook. This customer focused mentality from Alleanza made for a great house build experience and even 6 months after we continue to be in contact with Shaun and his team as the house shifts and settles on new improvements. Our customer house build process was a true partnership with Alleanza builders who were flexible, honest and above all practical and forthcoming with our investment, for our family. Additionally, he provided key resources/advice to us through the sale/rental and subsequent Harvey remediation efforts of our previous property. We continue to be impressed with the network of families/supporters that Shaun/Alleanza builds with the completion of each new home. He works hard at maintaining relationships across his customers including invitations to new open houses, key information on changes to the local community associations and even thoughtful gifts/card over the holiday seasons as a show of his appreciation. If I ever build a custom home again, Shaun/Carlos/Alleanza will continue to be our focal engagement.Read More

We purchaed our home from Alleanza in January 2014 and saw it through to completion in July 2014. During the whole process Shawn and his team were first rate and delivered an excellent product. The thought and design that went into our house was outstanding resulting in a very functional space where the entire family can gather. The finish was of the highest quality and we constantly get compliments on our home. What was equally impressive was Shawns responsivness when we had issues (not that there were many). He took complete ownership and gave us the impression that he really cared about his customers. Sadly we are leaving for pastures new but the biggest compliment came from my wife when she said to me "I wish we could just put this house on a truck and take it with us to Portland". I thouroughly reccomend Alleanza!Read More

Alleanza did a fantastic job with building our custom home. Both Shawn and Carlos are very personable and easy to work with. When we ran into a challenge, they were creative with coming up with solutions that would solve the issue. Carlos took the lead on building our house and was very attentive and quick to respond to text messages, phone calls and emails. They were also very courteous to our neighbors, always available. The inspections all went well and we love our new house!Read More

Working with the Alleanza team made building our house an enjoyable/fun experience! My husband and I purchased a lot with a tear down on it in June 2015 and started our search for a builder. We spoke with many builders, but Shawn stood out from the rest in his customer service approach, and really understood our vision of wanting a nice house but not wanting to overbuild (too much) for the neighborhood. Throughout the project he gave great advice on where we could get the bests value for our money. We broke ground in March 2016 and throughout the process Shawn and his team kept us informed on progress and addressed any/all questions and concerns. I really appreciated that most concerns I raised they were already on top of! If I did bring up something they weren't already working, there was no fighting over if it was a problem or not, just conversation on how to fix it and transparent conversation on options/cost involved. During the project we developed a high level of trust, which eliminated so much stress! The project was completed in November 2016, which was well within the targeted schedule and also within the budget they had provided. We used a reimbursable contract type (as opposed to fixed price), and I was very satisfied with the budget provided and explanations for deviations from it. Shawn really understood our vision, which provided great collaboration. There were a lot of things I had strong opinions on and drove decisions on, but others that I wasn't passionate about and was looking for suggestions on. They were very open to using new materials/vendors to meet my vision (weathered copper look metal roof, large walnut wood island, concrete counter tops, SS counter in outdoor kitchen, cement tile, etc.). On the flip side, Shawn always had great suggestions on finishing touches that I wouldn't have thought of such as keypad lock for back gate, matching backsplash for concrete counter top in bathroom from tile used on back patio, finish detail of base boards, outdoor kitchen sink/faucet, modular closets in kids rooms, etc. Overall, I would highly recommend working with Alleanza Custom Homes! Before starting this project, I had heard so many scary stories about building a house, but we really enjoyed the process and I think that the great job Alleanza did was a major contributor to this!Read More

In 2013, my wife and I decided to build our dream home on our existing lot in Garden Oaks. We interviewed several local builders and chose Alleanza Custom Homes. After meeting the owner, Shawn Sidoti, and touring one of his nearly-completed custom homes, the choice was a no-brainer. His price was fair and his reputation for quality work was well-known. Shawn got involved long before we signed a contract with his firm, and provided significant input into the design phase, even though we hired a separate architect. Over the ensuing months, as the project evolved, our partnership with the Alleanza team grew. The unavoidable snags that accompany all new home construction were handled with a thorough evaluation of options and mutual respect. We communicated regularly and, towards the end, almost daily. It became obvious to us that Shawn's talent was managing large projects, communicating effectively with his customers, and creative thinking. He clearly has a passion for designing and building homes. It was a total team effort, and Shawn always made us feel comfortable and in the driver's seat. He followed our (my wife's!) lead and we trusted him every step of the way. Building a new home is an enduring, stressful, and ultimately rewarding journey. Finding the right builder is critical to that journey. Shawn and Alleanza Custom Homes was the right choice for us.Read More

Alleanza custom homes is a very proffesional, customer and detail oriented company, They do high quality and beautifull work. it was a pleasure to work with them.Read More

After moving back from overseas, we needed to move into a home fairly quickly to get our kids into a school. We looked at a number of homes and settled on 1324 Althea. There were many choices in the area, but the home built by Shawn (Alleanza) was far and away our best option. The architecture was very unique with great features such as extensive interior brick work and large wooden beams framing a beautiful kitchen. The house was built with usability in mind... for example, the kitchen windows open up with hinges on one side, making it easy to pass disses from the indoor kitchen to the outdoor kitchen. Another example is a shower head on the back porch... perfect for cleaning off kids after a dip in the pool. The quality of the home is very high. There are many great built-in features that we use routinely (including large closet cabinets and safety lighting on the stairs). Shawn goes the extra mile to think about the common sense items people will enjoy. Last, Shawn also took great efforts to complete touch-ups as needed for any brand new house. We are quite happy to have bought the home from Alleanza.Read More

In 2014, my wife and I acquired a lot with a “tear-down” house in the Garden Oaks subdivision of Houston. Our realtor gave us a list of contractors engaged in home construction in that area, one of which was Alleanza Custom Homes. We toured a home that had recently been completed by Alleanza (we were very impressed) and then met with Alleanza’s Shawn Sidoti. We decided right then that Alleanza would be our contractor. Construction of a new custom home is a long process, involving literally hundreds of decisions by the homeowner. Throughout this process, the Alleanza team was always available to offer advice and support. Initially, they handled demolition of the existing “tear-down” house and helped us select an architect to design the home. Shawn reviewed all of the plans prepared by the architect and offered several suggestions to improve the final product. Upon completion of the architectural plans, the Alleanza team obtained the necessary engineering and foundation plans and the required building permits. The Alleanza team provided us with a list of recommended subcontractors for things like tile, plumbing fixtures, door and cabinet hardware, lighting fixtures, countertops, carpeting, and landscaping. However, in several instances (e.g., tile, plumbing fixtures, door and cabinet hardware, and landscaping) we decided to use other subcontractors of whom we were aware. In all cases, the Alleanza team worked very well with the subcontractors we selected, and we are very pleased with the results. Overall, we believe the Alleanza team deserves highest marks for honesty, integrity, reliability, and flexibility. The quality of the final product is excellent, and we are very pleased with our new home. Without reservation, we recommend the Alleanza team to anyone who is looking construct a new custom home.Read More

Alleanza Custom homes built a beautiful house for us.. We are very happy with the quality and the craftsmanship. Shawn Mc Gregor is an honest person. His pricing is transparent and there was no surprises in cost during the building process. Shawn provides excellent customer service, he is very responsive and always available for any questions/ concerns. He is also great to bounce of thoughts, design ideas and will be honest with his feedbacks of what is possible and if its even sensible to invest the extra $$$$.. He and his team are very creative.I highly recommend him..Read More

Shawn and the team at Alleanza built our home in 2015. As first-time home builders we truly appreciated Shawn's guidance, patience, professionalism, and transparency throughout the process. Every custom build poses unique challenges and ours was no exception. The best part of our experience with Alleanza though was Shawn's approach-ability and demeanor when we did not understand something or needed to make a change. Shawn regularly went beyond his obligation to us to ensure we were satisfied with the end product. We felt that the budgeting and business aspects of the build were transparent and fair. We are thrilled with the outcome and Alleanza has also been responsive to follow-up items over the last year. We would strongly recommend Alleanza to anyone building in the area!Read More

I have worked as a Lender for Alleanza Custom Homes for 3-4 years now. I totally respect Shawn. His product and especially his work ethics are 5 stars!! His product is so unique and he loves doing them for his clients. I would highly recommend Alleanza Custom Homes to people who are looking to build on a lot they own, are going to purchase or build on the lot where they currently live and are going to do a tear down.Read More
