Design and Build
This method involves getting the basic drawings as above and working closely with your builder throughout the project to agree and fine tune specific design details and finishes. This can provide a more organic process that will give you the chance to see spaces acquire dimension before deciding on finishes and layouts. A downside may be that it will also involve more continual client involvement, which may slow the process. It is also harder to assess what total project costs may be prior to the project being under way.
It is also possible to engage the services of an interior design professional to assist or act on your behalf in the design and build process.
