Custom home builds

At Sandstorm Construction, we believe that your home should be a reflection of your personality, taste and lifestyle. Your home should make you feel at ease and comfortable, but it also should be a place where you can gather with family and friends, or relax and unwind. Our team of architects will work with you to design a home that is modern and functional, while still remaining true to your personal style.

When it comes to building your dream home, there’s no shortage of options: from traditional bricks-and-mortar homes, to modern “smart homes” that use cutting-edge technology to make life easier.

Not sure where to start? From classic bungalows, to smart homes, to farmhouse chic, to modern townhomes and more, we’ll help you design and build a home that you’ll never want to leave.

Expert Home Additions

Need more space? We know what it’s like to love the home we’re in, but sometimes, to make it just right, we need a little more room as our families grow or circumstances change. Adding a home addition is the perfect way to create that extra room, without the need to move or relocate. We offer a full range of additions, including a second-story add-on, new office space, in-law or nanny suite, great room or family room, workshop or mudroom. We’ll help you make the most out of every square foot in your home, and help you add on what you’re missing.

How We Ensure a Successful Project

Every Sandstorm project starts with a detailed consultation to discuss your project and scope of work. How will your use your addition? How big should it be? Will it include a bathroom, kitchen or special electrical requirements? What kind of style and materials do you love?

We’ll ask you to create a list of “must-haves” and “nice-to-haves”, and work these into our drawings, design and purchasing that right materials for your vision and goals.

We will source the best materials for your project that will not only fit your budget, but that will be high-quality, durable and long lasting.

Your project manager will be with you every step of the way to provide you with transparent communication, updates, and to keep your project on track. We also assign our team of detail oriented, experienced contractors best suited to your project to complete your work.

We don’t like surprises, and when it comes to building your new home addition, neither should you! We outline your costs before the project starts so you know exactly what it will cost. We’ll work with you to make sure you get exactly what you want and stay within the budget we’ve set. If things change along the way, you’ll be the first to know and approve any changes.

Our Process

Step 1: Consultation

We start every project with an in-depth project review so that we can put together a comprehensive, individualized plan. In this meeting, we discuss your vision, goals, expectations, project timeline and budget. Here, you can provide us with your overall wishlist and prioritize the items as “must-haves” or “nice-to-haves”. From here, we activate the project development agreement and begin the design drawings.

Step 2: Assign a Design Team

In this phase, we create and confirm your vision. Based on your project scope and requirements, we will assign you a dedicated design team to your project.  You will also be assigned a project coordinator who will guide you through the project. At this stage, we determine appropriate zoning requirements and restrictions as well.

Step 3: Drawing Review

Here, we share design ideas and review your project’s preliminary drawings. We receive feedback and approval from the client, and work with you on desired changes to the overall design. 3D drawing can be provided if desired. We also take this time to discuss the budget and provide a rough project quote.

Step 4: Establish Project Details

Next, we start costing with key trade partners, finalize drawings, material selection, and the general budget. You can choose to join us for material selection or have us bring samples to you. We then conduct a home walkthrough and plan review. We also discuss areas for potential unforeseen problems and develop contingency plans as-needed.

Step 5: Building Phase and Milestones

During the course of the building and construction phase, we set up regular contact and weekly communication meetings, and set up a dedicated chat for progress updates, client questions and decision resolution. We also discuss the steps we’re taking to meet your budget, work quality and schedule.

Step 6: Home Sweet Home!

The moment you’ve been waiting for! In this final phase of the project, we do our final walkthrough and reveal, and explain how everything works, as needed. We follow this with a 30 day check in and one year check in, but in between those times, we’re always just a phone call away.

Sandstorm Construction recently completed a home renovation project for us and we couldn't be happier with the results. From the initial consultation to the final walkthrough, the team at Sandstorm were professional, attentive and always kept our vision at the forefront of the project. The new addition and deck they built exceeded our expectations and truly transformed our home. The quality of workmanship was outstanding and the attention to detail was impressive. We highly recommend Sandstorm Construction for any renovation needs. They are reliable, efficient and most importantly, they deliver on their promises.

I must apologize I have been late in providing this feedback. Jack and his team were extremely helpful. They correctly sized and advised what would be needed for our home. We replaced three columns, balcony and porch railings. We couldn’t be happier with the job they did. Thank you again.
