Our Fees:

Conceptual Design: This is usually a free service as part of the initial meetings with the agreement in principal to do the design. But no drawings will be given to the client for any length of time without payment first.

Measured Existing Drawings:††††††††† $1.00 to $2.00 /SF

Design Development:††††††††††††††††††††† $0.50 to $1.50/sf*

*This above fee will apply when more then one design package is required by the client to chose from. For example 3 design versions of a 300 square foot space @ $1/SF would be $300 each design. Existing drawing square footage portion would only be charged once. The final design is not charged for and is part of the Concept/Design to Working Drawings transition and swallowed in the overall fee.

Example above of 3 different proposed layouts of a back addition off an existing kitchen with 3 different deck designs and mud room configuration off the deck and bike storage area. This was for the Deforest project show on the website. In the end we settled on no deck or bike storage and a slightly different layout to the mudroom addition and new back stair to the basement.

Working Drawings: $1.50 to $3.00/sf

The above two items are usually combined for one price depending on the nature of the client and the situation, number of design schemes, etc.

example Fee for a 1000 SF existing house with a 500 SF new addition would be calculated as the following:

Existing Portion of House (Required for permit and is basis for new design)††††††† †††††††††††††††††††††††††††††††

1000SF X $1.00/SF= ††††††††††† $ 1,000.00

New Portion Concept, Design Development, and Working Drawings (New Permit Drawings)†††† †††††††††† ††

500SF X $3.00/SF= ††††††††††††† $ 1,500.00

Total Architectural Fee†††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††† ††††††††††† ††††††† †††††††††††††††††††††† ††††††††††††††††††††††††††††††††††††††††††††††† ††


Decks: Average deck $1000-$1500 depending on zoning headaches and site.

Garages: Average small single car garage $1000-$1500. A Double car garage would be $1200 and up depending again on complexity.

HVAC/Heat Loss Calculations: $1,000 on average.

Structural Design: Items that canít be engineered under Part 9 of the Code but only Part 4 of the Code (OBC) would need to be designed by a Structural Engineer. A fee would be determined on a case-by-case basis.

Generally houses can be designed under Part 9 of the Ontario Building Code. This is when the design live load is not greater then 2.5 kPa and clear spans are, generally speaking, not greater then 4.9m. There are special conditions when greater spans can also be designed under Part 9 of the code.

As long as the design is able to be kept to Part 9 the fee is included as part of the Working Drawing Fee, and no extra fees are charged.

A good rule of thumb here though is to assume around $1000.00. However depending on complexity and if required it could be more. Some projects may need some major beams, special foundations and footings, special retaining walls, underpinning or shoring, or helical piles.

Committee of Adjustment Hearings & Construction Review Fees:

$500.00 for each Committee of Adjustment hearing (includes documentation as required).

Construction Review: This is an hourly rate of  $100.00/hr. Note there should be at least the same number of visits by the permit drawings designer as the main municipal building inspector. Reviews should be done at least at the completion of the stages of foundations, framing, insulation, enclosing, and final completion/inspection. A review at the completion of the excavation stage when the initial setup of the foundations is taking place is also a good idea. This is to give the customer the insurance during the construction process that the contractor is doing things correctly and a good manner and as per the design.

Keep in mind we want your work. So all prices are negotiable. Let's meet and see what we can agree to do for each other.

Note partial payments at the end of each stage of the design & drafting will be requested. At each payment point you will get a hard copy of the drawings. If you do not like what you see at that point you do not have to pay. But you will not receive any hard copy of the drawings at that point in the design for something you did not like, or want to pay for.
