STEP 1. PREPARE FOR YOUR PROJECT

To avoid expenses and delays it is important that you prepare details for your new construction project before buying your house plan and contacting us. Here are the important information regarding your future home plan that you need to collect prior to contacting us:

  • Buy the land and verify with your municipality about the rules governing your area such as setbacks, mandatory building materials, etc.
  • Verify your available financing for the construction of your house or cottage from your banking institution.
  • List the essential elements of your custom home design. This list varies from one family to another and must include: the desired architectural style, the number of bedrooms and bathrooms, required additional rooms such as an office, a gym, a games room, a sheltered balcony (rear or side), desired type of foundation, etc.
  • Add photos and / or sketches, as needed.

STEP 3. RECEIVE YOUR ESTIMATE within 7 working days

etape-1

Within 7 working days following the receipt of your documents by email or a meeting at one of our 31 Drummond House Plans regional offices, or at a time agreed between us, a written estimate and details regarding our service offer and timelines regarding initial project delivery will be provided for your approval. The delivery time of a construction plan can vary from a few days to a few weeks depending on the time of year. Following the receipt of your preliminary plans, timelines may be readjusted depending on the time required for your reflection and the number of revisions required.

STEP 4. COMPLETION AND DELIVERY OF YOUR PRELIMINARY PLAN

Following the approval of our estimate (STEP 3) as well as acceptance of the delivery timelines of your final plan, sketches can be made for you to ensure that we have the same vision as you have of your project.

  • We will then proceed with the production of the preliminary plan which may include, among other things, floor plans and elevations of the 4 sides of the house, or any other information relevant to your project.
  • We will then follow up by emailing or handing over your preliminary plan to ensure that all details are in line with your expectations. If you wish, and we have provided for by agreement, different design options can be presented to you.
  • At this stage we will make corrections as needed until the entire plan is perfect for you. One to three discussions or meetings are usually enough to allow you to approve the final project.
  • It is always possible to add various additional services to your plan such as the electrical plan.
  • At this stage it is also best to get quotes from one or more construction contractors
