Creating the Components

Completing Your Model

Crafting a high-quality model building can finish off a diorama for a school project, add depth to a model train setup, or assist in visualizing intricate construction plans. Assembling your own model buildings is simpler than you might expect—in most cases, all you need is a blueprint and a few basic, affordable materials. Begin by sketching out a simple design for your building, then transfer its individual sections onto your chosen material and cut them out manually. Once you've prepared each component, it's just a matter of joining them together with adhesive and adding the final touches.

Steps

Planning Your Structure

Determine the type of building you want to create. Before you start assembling your model building, you must have a clear idea of its appearance. Observe different building styles in your surroundings to draw inspiration and refine your mental image, or let your imagination run wild to develop a unique structure. If you can visualize it, you can construct it.

If you intend to replicate an existing building, take numerous photos to serve as references during the design process.
A simple house, barn, or other conventional structure will be the easiest to construct initially. As you gain experience, you can attempt more intricate designs such as mansions, skyscrapers, castles, and other architectural wonders.

Pro Tip: Don't hesitate to tweak the design of an existing structure to better suit your skill level and the materials you have on hand.

Draw your building from different viewpoints. Take a seat with a pencil and a piece of paper and sketch a rough draft of your building, depicting its appearance from various angles. Ensure that you include a view of the roof and any notable architectural elements.

Sketching your building will give you a clearer visualization. It will also assist you in transferring the individual components of the structure to your working materials when the time comes.
Your sketch doesn't need to be flawless—it will simply serve as an initial visual aid to assist you throughout the process of cutting and assembling the various pieces of your model building.

Adjust the size of your model to match the original structure if you're replicating a real building. To create a scaled-down replica with precise dimensions and proportions, begin by determining the height and width of the building you wish to replicate. Once you have this information, refer to an online modeling scale conversion chart to convert your measurements to the desired scale, which you'll then use for your model.

Modeling scales are expressed as fractions that indicate the size of the model relative to the actual object. For example, a 1/125 scale means that it would take 125 of your model pieces lined up end-to-end to match the length of the real building.
You might be able to find the exact dimensions of a particular structure in local building records. Perform a quick search for “building records” along with the name of your town or city and the name or address of the building to access its original blueprints.

Transfer each section of your building onto sturdy cardstock. Now that you have a clear idea of your building's design and dimensions, it's time to transfer your plans to your chosen materials. Outline each main component of the building, such as the floors, walls, roof, and any additional features like chimneys, gables, flower boxes, or guttering.

You can also opt for materials like styrene, mat board, foam core, or balsa wood instead of cardstock. While these materials may differ in cost and durability, they are all easy to cut and shape.
If you want your model building to feature openings for doors and windows, be sure to include them in your sketches.

Creating the Components

Use a utility knife to carefully cut out the components of your building. Follow the outlines you previously drew, using a metal ruler or straight edge to guide the knife. Apply gentle pressure and make multiple passes rather than trying to cut through the material in one go. Snap the piece free by hand after cutting. For tougher materials like styrene or wood, you may need to go over the outlines several times.

Place scrap cardboard under your materials to protect your work surface. Consider investing in a self-healing cutting mat if you plan to do a lot of modeling.
A pen-style knife offers better precision and control than one with a wider handle.

Caution: Always exercise caution when handling a utility knife, as the blade is extremely sharp and even a minor slip can cause injury.

Score the outlines of openings like doors and windows to make them easier to remove. Start at one corner and carefully score each side of the outline with your knife. Then, press down on the excess material at the center of the opening to free it. If needed, extend the cuts all the way to the edges of the piece and glue them back together without the material from the openings.

Scoring the outlines will result in cleaner openings without over-cutting into the surrounding material.

Fold or score the roof to create it from a single piece of material. Instead of piecing together multiple sections, draw an additional line on the roof outline where the sides meet. Fold the material along this line to form the roof point. For styrene, wood, or gel foam, make a shallow cut along the roof line and bend the material to create a hinge.

This technique works well for simple roof styles like gable, gambrel, and skillion roofs.
For more complex roof designs, cutting and pasting may be necessary.

Replace the blade of your utility knife when it becomes dull. Cutting and scoring will gradually dull the blade. If you feel resistance or notice rough cuts, replace the blade immediately. Carefully remove the old blade and insert a fresh one. Cutting with a dull blade can tire you out quickly and damage your materials.

If using a retractable knife, take care when removing the blade to avoid accidental cuts. Some blades come with pre-notched sections for easy replacement.
Using a sharp blade ensures clean and precise cuts without damaging your work.

Completing Your Model

Use adhesive to join the different parts of your model together. Apply a small amount of strong craft glue to the edges of the first piece. Align it with the corresponding edge of the adjacent piece and hold them together until the glue sets. Consider using a hot glue gun or super glue for faster bonding.

You can also opt for white glue on wood and most types of cardstock.
To simplify the process, start by assembling the outer walls around the base, then add any interior walls before attaching the roof.

Pro Tip: While gluing may be time-consuming, it's crucial for achieving a clean and precise finish. Take your time to ensure each connection is well-made.

Consider adding a layer of clay to the exterior of your model (optional). Apply soft modeling clay in small patches over the skeleton of your structure. Flatten and shape the clay to achieve an even surface, being careful not to damage the underlying material.

Gently pinch the clay at the joints for sharper edges and corners.
Standard modeling or air dry clay works well for most projects. Choose a neutral color if you plan to paint the model later.

Add textures and intricate details to the clay using a utility knife. Use the knife to create patterns such as masonry stones or brickwork. Refer to photos for authenticity and precision.

You can also use the knife to simulate roof tiles, window sills, and other features.
If hand-carving is too tedious, consider using embossed vinyl or plastic sheets for a similar effect.

Enhance realism by painting your completed model. A meticulous paint job adds lifelike details to your model. Use various shades to capture the colors of different building materials such as stone, brick, wood, roofing tiles, and metal. Acrylic or tempera paint is suitable for clay surfaces.

If you covered your model with air dry clay, cure it in the oven on the lowest setting for 15-20 minutes, ensuring the oven cools between cycles to prevent burning.
Consider hiring a 3D printing service or a laser cutting shop for precise pieces, or utilize CAD software for detailed designs.
