Object Drawing Lessons
This lesson teaches a stylized doghouse drawing by building a front face, projecting a side face toward one vanishing point, adding a gable roof, and placing an entrance. All dimensions are hypothetical drawing values. The construction below defines a simple worksheet perspective; it is not a building plan or a universal doghouse proportion.

Build the body and roof structure
Draw the front face as a rectangle in the picture plane. Its edges stay horizontal and vertical. To show depth, do not draw a second equal-height rectangle beside it: send the front-right top and bottom corners toward one vanishing point, then join points partway along those rays with a vertical rear edge. The side face is a projected quadrilateral whose top and bottom edges recede.
Draw a gable triangle on the front face with its peak centered over the front wall. The ridge begins at that front peak and recedes toward the same vanishing point as the side-face edges. The two front roof slopes should mirror each other around the gable centerline. Use a small overhang only if it follows the same receding direction; keep the construction lines light until the front and side faces agree.
- Draw the front wall rectangle with the stated width W and height H.
- Place the vanishing point at (W+2D, H/2), using the chosen drawing depth D.
- Draw rays from the front-right top and bottom corners to the vanishing point; mark the rear edge at x=W+D, where the rays have reached halfway.
- Join those two points with a vertical line to complete the side-face quadrilateral.
- Add the front gable peak, mirror its two slopes, and extend the ridge toward the vanishing point.
Add the entrance and simple perspective
The entrance is an opening in the front face. A common shape is a rectangle with a rounded top, but a simple arch or rectangle is also valid. Place the entrance centered on the front face, leaving at least 1 unit of wall on each side and below the roof line. Draw the opening with clean edges; if you use an arch, keep the curve symmetrical about the vertical center line.
For the one-point construction, keep front-face edges horizontal and vertical. Side-face top and bottom edges recede toward the vanishing point; the rear wall edge stays vertical. The ridge is another receding edge and follows the same vanishing direction. A halfway rear edge is an explicit worksheet choice that makes the side face easy to construct and check.
- Draw a horizon line and mark one vanishing point on it.
- Keep the front face edges horizontal and vertical; do not tilt them.
- Draw the side face top and bottom edges from the front-right corners toward the vanishing point, then close them with a vertical rear edge at the halfway point.
- Place the entrance centered on the front face, leaving at least 1 unit of wall on each side and below the roof line; keep the entrance edges vertical and horizontal (or symmetrical if arched).
- Check that all receding lines meet at the vanishing point and that vertical edges remain vertical.
Check proportions and line quality
Use these proportions as drawing choices, not building standards: a front face 1.5 to 2 times as wide as it is tall, a roof rise about one third to one half of wall height, and an entrance centered on the front face. Adjust them if needed while keeping the front face, receding side, gable, and opening legible.
Line quality supports structure. Use a light construction line for the box and ridge, then a firmer line for the final edges. Keep parallel edges parallel where they should be, and keep vertical edges vertical. If a line looks wobbly, redraw it with a single confident stroke. Erase construction lines only after the final edges are clear.
- Measure the front width and height with a ruler; record the ratio.
- Check that the roof height is between one third and one half of the wall height.
- Check that the entrance width is about one third of the front width and centered.
- Trace the final edges with a firmer line, keeping verticals vertical and parallels parallel.
Worked example
Draw a doghouse front face 6 units wide and 4 high, with drawing depth D=3, a 1.5-unit gable rise, and a centered 2-by-2.5 entrance. Use VP=(W+2D,H/2) and place the rear side edge halfway along rays from the front-right corners.
Worked answer
Front face: rectangle from (0,0) to (6,4). Place VP=(12,2). Rays from the front-right corners (6,0) and (6,4) reach the halfway rear edge at x=9: its bottom is (9,1) and top is (9,3). Join them vertically; the side is a projected quadrilateral, not a 3-by-4 rectangle. Put the front gable peak at (3,5.5), using the 1.5-unit rise, and mirror the two front slopes. Extend the ridge from that peak toward VP until it meets the rear roof. Center the 2-by-2.5 entrance from x=2 to4 and y=0 to2.5. The front width-to-height ratio is 6:4=1.5:1, and the roof rise is 1.5/4=0.375.
Four practice exercises
Exercise 1
Draw a dog house with a front face 8 units wide and 5 units high, a side depth of 4 units, and a gable roof with a 1.5-unit rise above the front wall. Place the ridge at the midpoint of the top edges. Add a centered rectangular entrance 3 units wide and 3 units high. Use one-point perspective with the vanishing point on the horizon. Describe the needed diagram in words: front rectangle 8 by 5, side face projected with D=4, ridge connecting midpoints, entrance centered.
Show answer and check
Front face 8 by 5. Put VP=(16,2.5). Rays from (8,0) and (8,5) reach the halfway rear edge at x=12, y=1.25 and y=3.75; join these points vertically to form the projected side. Use a front gable peak at (4,6.5), 1.5 units above the 5-unit wall, and extend the ridge toward VP. Center the 3-by-3 entrance at x=2.5–5.5, y=0–3. The side top and bottom recede; the rear edge stays vertical.
Why: The front ratio is 8/5=1.6. The entrance margins are (8−3)/2=2.5 on each side, with 2 units between its top and wall top. The rear edge coordinates come from halfway along each ray toward VP.
Check: Confirm the front rectangle is 8 by5, VP is (16,2.5), rear edge is x=12 from y=1.25 to3.75, front gable peak is at (4,6.5), entrance margins are both 2.5, and both side rays meet VP.
Exercise 2
Draw a dog house with a front face 7 units wide and 4 units high, a side depth of 3 units, and a gable roof with a 1.5-unit rise and a centered ridge. Add a centered arched entrance 2 units wide and 2.5 units high. Use one-point perspective. Describe the needed diagram in words: front rectangle 7 by 4, side face projected with D=3, ridge connecting midpoints, arched entrance centered.
Show answer and check
Front face 7 by 4. Put VP=(13,2). Rays from (7,0) and (7,4) reach the halfway rear edge at x=10, y=1 and y=3. Join them vertically. Center the 2-by-2.5 arched entrance at x=2.5–4.5, with its bottom at y=0; keep the arch symmetric. Put the front gable peak at (3.5,5.5), 1.5 units above the 4-unit wall, and extend the ridge toward VP. The side is a projected quadrilateral, and its receding edges converge to VP.
Why: The front ratio is 7/4=1.75. Entrance side margins are (7−2)/2=2.5; its height is 2.5/4=0.625 of wall height, and 1.5 units remain below the opening.
Check: Check VP=(13,2), rear edge x=10 from y=1 to3, equal 2.5-unit entrance side margins, a symmetric arch, and receding edges that meet at VP.
Exercise 3
Draw a dog house with a front face 6 units wide and 4 units high, a side depth of 2 units, and a gable roof. Place the ridge at the midpoint. Add a centered rectangular entrance 2 units wide and 2 units high. Use one-point perspective. Then check the roof height: if the roof rise above the eaves is 1.5 units, is it within the guideline of one third to one half of the wall height? Describe the needed diagram in words.
Show answer and check
Front face 6 by 4. Put VP=(10,2). The halfway rear edge is at x=8, y=1 to3. Draw the side top and bottom from the front-right corners to VP and close them with that vertical edge. Center the 2-by-2 entrance at x=2–4. Put the gable peak at x=3 and use a roof rise of 1.5 units; its ratio to wall height is 1.5/4=0.375, within the stated one-third-to-one-half drawing guide. Extend the ridge toward VP.
Why: A 1.5-unit roof rise divided by 4-unit wall height is 0.375, between one third and one half. The entrance is centered and its side margins are 2 units.
Check: Verify the side construction uses VP=(10,2) and rear edge x=8 from y=1 to3. Compute 1.5/4=0.375 and check entrance margins and ridge direction.
Exercise 4
Draw a dog house with a front face 9 units wide and 5 units high, a side depth of 4 units, and a gable roof with a 1.75-unit rise and a centered ridge. Add a centered rounded-top entrance 3 units wide and 3.5 units high. Use one-point perspective. Check the entrance height: is it within two thirds of the wall height? Describe the needed diagram in words.
Show answer and check
Front face 9 by 5. Put VP=(17,2.5). Rays from (9,0) and (9,5) reach the halfway rear edge at x=13, y=1.25 and y=3.75. Join them vertically. Center the 3-by-3.5 rounded-top entrance at x=3–6, y=0–3.5; its height ratio is 3.5/5=0.7, above the two-thirds guide. Reduce it to 3 units high if you want to meet that guide. Put the front gable peak at (4.5,6.75), 1.75 units above the 5-unit wall, and extend the ridge toward VP.
Why: The opening width is 3/9=1/3 of the front width, while its height 3.5/5=0.7 exceeds two thirds. The suggested 3-unit revision gives a ratio of0.6 and keeps it centered.
Check: Check VP=(17,2.5), rear edge x=13 from y=1.25 to3.75, front gable peak is at (4.5,6.75), equal 3-unit opening margins, and compare 3.5/5=0.7 with two thirds; after correction verify 3/5=0.6.
Common mistakes
- The roof slopes are unequal, making the ridge look tilted. Measure the horizontal distance from the ridge to each eave and the vertical rise; make both sides match.
- The side face receding lines do not meet at the vanishing point. Use a straight edge to extend the top and bottom edges of the side face; adjust them until they converge at the marked vanishing point.
- The entrance is off-center or too close to the roof line. Mark the center line of the front face and measure equal distances on each side; leave at least 1 unit below the roof line.
- The front face edges are tilted instead of horizontal and vertical. Check with a ruler or the paper edge; redraw the front face edges parallel to the paper edges.
Self-check rubric
- Body is a clear rectangular box with front and side faces sharing a vertical edge.
- Front roof peak is centered and the ridge recedes toward the same vanishing point as the side face.
- Front roof slopes mirror across the gable centerline; entrance is centered and leaves the stated margins.
- One-point projection is consistent: front edges stay horizontal/vertical, side top/bottom and ridge recede to the vanishing point, and rear vertical edges stay vertical.
- Proportions are consistent: front width-to-height ratio between 1.5:1 and 2:1; roof height one third to one half of wall height.
- Line quality is clean: final edges are firm, construction lines are light, and parallel edges stay parallel.
- Entrance alternatives such as a rectangle, arch, or rounded top are acceptable if centered and within the stated margins.
Questions and answers
Do I need a ruler?
A ruler helps with straight edges and consistent measurements, but you can use any straight edge. The key is to check that parallel edges stay parallel and receding lines meet at the vanishing point.
Can the entrance be a rectangle instead of an arch?
Yes. A rectangle, an arch, or a rounded-top rectangle are all valid. Keep the opening centered and leave enough wall around it for structural clarity.
How many vanishing points should I use?
This lesson uses one-point perspective. The front face stays parallel to the picture plane, and the side face recedes to a single vanishing point. Two-point perspective is outside this lesson's boundary.
What if my dog house is wider than it is tall?
That is fine. Keep the roof height proportional to the wall height and keep the entrance centered. The guidelines are starting points, not fixed rules.
