How to Create an As-Built Sketch for Remodeling

Introduction

Creating an as-built sketch is an essential step in the remodeling process. A well-documented sketch provides an accurate representation of your home’s existing layout, ensuring that any modifications align with structural realities. Whether you are working with a contractor, applying for permits, or planning renovations yourself, having precise measurements and clear drawings will save time, reduce errors, and help visualize the final outcome. In this guide, we will walk you through the steps to create a comprehensive as-built sketch, from gathering materials to finalizing your plans.

What You’ll Need

Before you start, gather the following tools:

• Tape Measure – A 25-foot tape is ideal for measuring room dimensions.
• Grid Paper – Minimum size 8 1/2″ x 11″ to help maintain scale.
• Pencil – Allows for easy corrections and adjustments.
• Digital Camera – To capture details that are hard to sketch.
• Clipboard or Hard Surface – Provides support while sketching in the field.

Step 1: Measure and Sketch the Interior

Accurate interior measurements are the foundation of your as-built sketch. Follow these steps:

1. Room Measurements – Walk through each room and measure its width and depth.
2. Drawing the Layout – Use the grid paper to draw the room layout, treating each square as a foot (12″). Keep lines straight and proportional.
3. Doors and Windows – Mark all door and window openings relative to their positions.
4. Labeling Dimensions – Write window dimensions as width x height (W x H) next to each window. For doors, note the width within the opening.
5. Noting Unique Features – Sketch fireplaces, built-ins, and any architectural details that may impact remodeling plans.
6. Photographic Documentation – Take pictures of intricate features or areas that are difficult to measure.

Tips for Accuracy:

• Always measure from wall to wall, not from trim to trim.
• Measure multiple times to confirm accuracy.
• If possible, work with a helper to hold the tape measure steady.

Step 2: Photograph the Exterior

A complete as-built sketch also requires a visual reference of the home’s exterior. Take photographs from the following angles:

• Front View – Shows the overall facade.
• Front Right Corner – Captures depth and side details.
• Right Side – Documents windows, doors, and features.
• Right Rear Corner – Provides a different perspective.
• Rear View – Shows backyard structures and wall layout.
• Rear Left Corner – Complements other angles.
• Left Side – Documents additional features.
• Left Front Corner – Helps establish depth.
• Unique Exterior Features – Includes chimneys, decks, porches, and architectural details.

Why This Matters:

Photographs supplement sketches by showing dimensions and details that might be overlooked in drawings.

Step 3: Document the Floor System (If Applicable)

Understanding the floor structure is essential for load-bearing considerations:

• Homes with Basements or Foundations:
  • Photograph floor joists or trusses beneath the floor.
  • Measure joist depth and spacing.
• Homes on Slabs:
  • Skip this step, as there are no underlying joists.

Additional Considerations:

• Identify load-bearing walls based on joist orientation.
• Note any signs of sagging or uneven flooring.

Step 4: Gather Site Plan Information (If Required)

Many remodeling projects require site plans for permits or zoning compliance. To prepare:

1. Obtain Property Documents – A surveyor’s plat or tax map will provide a starting point.
2. Measure Driveway and Walkways – Note their size and location.
3. Mark Trees and Landscaping – Indicate which trees will be preserved or removed due to remodeling.
4. Identify Utility Lines and Easements – This can prevent costly mistakes when modifying the structure.

Step 5: Sketch Your Planned Additions

Once you have documented the existing layout, sketch your proposed changes:

• Use a separate sheet of grid paper for additions or modifications.
• Indicate where walls will be moved or extended.
• Clearly label new window and door placements.
• Use arrows or different line styles to show additions vs. existing structures.

Creating an as-built sketch is a critical first step in any remodeling project. By carefully measuring, sketching, and photographing both the interior and exterior, you ensure that your remodeling plans are based on accurate, real-world data. This process reduces errors, helps secure permits, and provides clarity when working with contractors. With your as-built sketch in hand, you can move forward confidently, knowing that your remodeling vision is well-documented and achievable.
