The basic rule of thumb is if your project costs more than 5% of the value of your house, or if you are making structural changes to the interior or exterior of your home, or if you are making significant changes to the floor plan of your home, you need an architect for your project.
This is the part of the project where the design build approach will add significant value and save you a lot of money over the life of your project. Its best to find a contractor that will work with the architects and have long term relationships with many very good architects. This can get you better pricing for their services for your project than you can by contacting them directly. They will pass that savings on to you.
Once you select the architect you want to use for your project, the contractor will work with them throughout the design process to make sure they are designing a project that fits into your budget. We cannot understate how important this is for the success of your project and we have seen many projects never get off the ground because this step was not followed. Your architect is not paid to tell you no. If you tell him you want something, he assumes you can afford it. The time to determine how much your project is going to cost is during design, not after design is complete.
Once the architect finishes the design it is time to pull permits and build your dream. Proper planning and constant communication are the keys to success.
Before the work is started, you should sit down with the contractor and have a project kickoff meeting. At this meeting you will go over the construction estimate with you in detail as well as present you with a construction schedule so you can make plans to minimize the effect of the project on your day to day life. You will also be provided with a list of items you need to select, the budget for those items (with the contractor discount), and the schedule of when those items need to be selected to meet the construction schedule.
Once we begin construction we will communicate with you about the status of the project however often you like, but we recommend status meetings weekly at a minimum. If something comes up of major importance we will contact you immediately. We will never proceed with work that is different than the original estimate before we have approval from you in writing.
