I now have a Matterport Pro2 3D camera for ​capturing site conditions, or taking 3D "As Built" walkthroughs, rough framing views, creating floor plans for MLS listings, etc.. This is 98-99% accurate within range and will allow for 3D views and ​getting measurements from them. This should also decrease time on site and cause less disruption for your clients.

Meet the owner,

I have always been fascinated with the process of construction. As time went by, it was evident that my focus was toward residential buildings and their design. Following my passion, I earned my Associates Degree in Architectural Engineering Technology from Wentworth Institute of Technology in 1981. Shortly after graduation, a chance conversation with a local contractor led to my filling his need for plans to be drawn and Chapman Design Service was initially started. Over the years since, I have had the opportunity to work with and for lumber yards, contractors, building material distributors, manufacturers and wholesalers. This has given me the knowledge and ability to better understand the multi-faceted sides of the design and construction industry and I incorporate this knowledge into the designs for my clients.

Chapman Design Service was re-launched in 2013, using computer aided design with the Chief Architect® Home Designer Pro CAD program. This allows your client’s visions to become reality with a simpler design process, color elevation and 3-D views, and a much quicker way to make revisions. Once the plans are ready, next is the ability to generate the construction documents needed to apply for building permits. This technology has made the design process flow much faster than the old days of paper, T-square and triangles!

I will provide you with a professional design to meet your client's individual needs. Think of me as being an on-call designer so you don't have to draw the plans yourself or hire a person full time in-house to fill that need. I can also modify plans you may already have from your clients or other sources. I look forward to the chance to work with you.

Thank you,


Frequently Asked Questions (FAQ's)


Q: What is the process for you to get started on plans for a project?

A: After our initial conversation, I'd want to meet with you at the project location to take pictures of the project area, take needed measurements, and note existing conditions of the site such as approximate grade, floor heights, materials, and other design elements to make sure I can incorporate your individual needs in your plans. With a new house, we can meet where convenient to go over ideas, needs, and details. If you already have a plan from a service, magazine, etc., they can be emailed to me as well. I have a list of references available which I can supply you at your request.​

Q: Are you an architect?

A: I have my Associates in Engineering in Architectural Engineering Technology from Wentworth Institute of Technology. However, I am not a licensed/registered architect, engineer or contractor. Residential projects in Massachusetts do not require an architect to prepare the design and plans for the construction, enlargement or alteration of (a) any building containing less than thirty five thousand cubic feet of enclosed space, and/or (b) any single or two-family house or any accessory building thereto. You should check with your local building inspection department beforehand, as some towns may require an engineers stamp and/or lateral load analysis. I can provide you with the contact information for an engineer, if required. Many of the lumber yards have staff on hand that can assist with engineered material design as well.


Q: Do you charge for the initial site visit?

A: This is done at no charge. I will then submit a written price estimate to you for the drawings after our meeting. I'd then await your approval of my Estimate/Quote, Terms and Conditions and retainer deposit before I begin the design. Please note: Customer assumes all responsibility that project(s) falls within property boundaries and/or setbacks as required.

Q: What is the normal lead time to get the plans?

A: I expect to have a preliminary design to you for review within 2-4 weeks after our initial meeting, depending on the project scope.

Q: Do you charge for changes to the design?

A: My pricing includes up to 2 (two) rounds of revisions to the preliminary plan once it is sent to and received by the client. After that, changes initiated by the client are billed on an hourly basis. The plans are emailed to the client in PDF form for viewing. 

Q: Do you perform rating or energy calculations?

​A: Any required rating and energy code compliance such as HERS, REScheck, etc. are to be supplied by others


Q: Do you draw the entire existing house as a part of a remodeling project?

A: Plans include the general area surrounding the project, not the entire structure.​ Some towns need the actual house to be shown for elevations, etc.  If needed, that can be provided for an additional fee. Be sure to mention that when we set up the site visit.


Q: Do you offer 3-D views of the project?

A: Yes. Color 3-D views are included with the preliminary design to show exterior elevation, overhead floor and other views which may be helpful for clients to visualize their project. Please note I do not show the exact interior colors/finishes, furniture or design aesthetics, as these views are for concept and illustration purposes only. 


Q: What drawings do you include with your plans?

 A: Your personalized plans include (as applicable):

·         Foundation plan

·         Floor plan(s)

·         Exterior elevation views (up to 4, depending on project type)

·         A detailed section view

·         Door & window schedule

·        Floor, ceiling & roof framing plans – The engineered material supplier will usually design and prepare those for I-joist framing and/or roof trusses when used.

Up to 6 sets of plans are printed on 11” x 17” paper. Or sent as a PDF to the client and they can print the plan themselves. Customer will pick up their plan copies at the "Staples™" location of their choice.

Some projects will need to be printed on 18” x 24” or 24" x 36" paper as needed or requested. A printing fee for these sizes will be added to the final invoice. Customer will pick up their plan copies at the "Staples™" location of their choice.


Please note: I do not provide plot plans, septic plans, electrical plans, plumbing plans, HVAC plans, irrigation design, security system design, etc. Those are for the trades that do that actual work and know their respective codes to design.


Q: What if there is a need to cancel the project?

A: Cancellation policy: Should the Customer cancel the project before the plans are completed, the Customer will be invoiced at the current hourly rate of $65.00 per hour for the time spent on their project up to and including the cancellation date. All cancellations must be submitted by email or phone with a received follow up confirmation from Chapman Design Service, LLC.


Q: What type of payments do you accept?

A: I accept checks, ACH Bank Transfers, and cash. Plus Visa, MasterCard, American Express and Discover debit/credit cards.
