Our Process: 
1. Before hiring a builder…

The first step is to sit down together and discuss what you are looking for. If you already have a location, our team will go scout it and discuss the possibilities and limitations of the site based on its location. We will take everything into consideration and make a realistic assessment of the feasibility of the site and provide you with an estimate. 

2. Budgets

Afterwards, we will openly and honestly discuss the project’s cost. We adopt a due diligence culture, and we will work with you completely transparently to accurately understand the cost of labor, as well as the cost of specific finishing details. We will go over every aspect of your project with you to help you make an informed decision about the type of home you want to build and ensure it fits within your budget.

3. Pre-Construction

The real fun begins when you decide to move forward with the project. We’ve gotten to know you as a client by this point. We’ve discovered what you enjoy and care about the most. Our goal is to create a home that reflects your personality, a house in which every square inch reflects exactly what you want. With hundreds of successful projects under our belt, we know how to look after you during this delicate process.

4. Construction

Once the city signs off on the plans, the actual construction begins. For every project, we assign a dedicated project manager so that you know exactly what is happening and when. Each week, your project manager will update you on what has been done and what is up next. This is beneficial not only to you, but also to us in staying on top of all potential changes and making key decisions throughout the process.

 Whatever type of home you are considering, chances are we’ve built something similar before, so whether you want to add a second story or design & build a new home from the ground up, our team will do everything we can to ensure that your new home is a long-term success.
