We were recently contacted from a homeowner regarding our Consulting services, regarding a comparative cost analysis of Architectural services, for a new ground up home or adding a pop-top.
Below is a re-cap overview of the line item analysis:
The overall time needed for a complete set of architectural plans to be prepared for submittal to City agencies, is obviously somewhat more for a new home, but the driving factor regarding the cost increase, comes from the engineering required.
Additional structural engineering for foundations and framing; civil engineering required for site work/drainage/retaining walls, energy engineering analysis and new hvac, electrical, plumbing systems and equipment needs, all require extra time. Additionally, these details and specifications need to be coordinated with the architectural plans, in the proper places.
The above work is typically performed by our CAD drafters, with pertinent decision making and direction, coordinated by myself as the Architect for the project.
So in general, the Architect and engineering fee will be approximately 25%-35% more. As well, the construction cost ‘differential’ must also be factored into the overall budget, to obtain the total out-of-pocket expenditure for design and construction of a new home.
For other Consulting services, including comprehensive line-item construction cost analysis, send us an email with your inquiry.
Best Regards Always!
