Our Services

We offer a comprehensive design-build service for home renovations, custom home builds and home additions. Our years of experience enables us to take you from concept to completion in a seamless process as we take full accountability for design, architecture and construction.

Step by Step

Our Process

We make a complicated industry easier to navigate by guiding you through every phase of your building project.

During the discovery call, we focus on understanding your project, taste, and style to ensure our services align with your needs. Following this call, we schedule a site visit to gain a deeper insight into the project's specifics and overall scope, further ensuring our company is the perfect match for your vision.

We provide a clear outline of the construction work and a detailed, categorized cost estimate to ensure full transparency. Along with this, our contract is presented, setting a solid foundation for our partnership and project success.

We gather detailed insight into your personal preferences and style, then collaborate with you to create a design you’ll love. We assist in specifying materials, fixtures, and other elements to be included in the design that embody your vision. Finally, we provide 3D renderings and material samples to help you visualize the transformation.

You will receive updated, detailed pricing post-design finalization. We then complete essential engineering and drafting, and obtain all necessary permits. This phase ensures everything is meticulously prepared and compliant for smooth project execution.

Once construction starts, we prioritize constant communication while your project progresses. Our team foresees potential obstacles, minimizes delays, and handles each phase of the construction smoothly and efficiently.

After the project is completed, we make sure your space gets a thorough cleanup. We then take you through a final walkthrough to ensure that every last detail is exactly as you want it. Afterwards, we guarantee peace of mind with our 2-year warranty, knowing we are just a call away.
