Today, we’ll learn how to build a portico. A portico is an area that acts as the entranceway to a building. It is usually made up of columns and has a roof. This is a complex project so follow along closely!
I love architecture. I remember walking into St. Peter’s Basilica for the first time and just being awestruck. The same thing happened when I paid my first visit to Rome’s Pantheon . . . or, Notre Dame . . . or the Colosseum.
🛠️ What This Is About
Let’s turn your portico ideas into simple, step‑by‑step instructions that anyone can follow—even if you’ve never built one before.
🧱 How It Works
A portico is a small porch or overhang supported by columns.
It protects your entrance from rain or sun and adds instant curb appeal.
It can be single-tier (one level of columns) or double-tier (two levels).
📋 Materials or Tools Needed
Lumber (2×4, 4×4, etc.) for framing
Columns (wood, stone, metal, or prefabricated)
Roofing material (shingles matching your house)
Brackets or braces (wooden or decorative metal)
Screws, nails, flashing, waterproof filler
Tools: drill, saw (miter or circular), level, tape measure, paintbrush
⚙️ Step-by-Step Instructions
Check your budget
Decide if you’ll DIY or go with a prefabricated kit. Prefabs are convenient if funds are tight.
Plan and check space
Use auto‑CAD, SketchUp, or full‑size board layout to draw to-scale or full-size templates
Make sure the area is wide and tall enough near your door.
Frame the brackets
Build an “L” shape by screwing 2×4s together—one piece attaches to your wall, the other sticks out. Add a diagonal brace.

Attach brackets to the house
Remove siding about 18″ above where they’ll go. Lag-screw into studs, then flash and reinstall siding to prevent leaks.
Build and install truss/roof frame
Figure your roof pitch using a level (e.g., 25°–27° for 6/12 pitch). Cut rafters accordingly and nail them together into a gable.
Secure the truss to the mounted brackets.
Add sheathing and shingles
Install plywood or slats over rafters, seal screw holes.
Apply shingles starting from the bottom, add trim and gutter.
Finish and protect
Flash the intersection with your house correctly.
Paint, caulk, and seal all wood surfaces. Routinely inspect and maintain.

From r/ExteriorDesign:
“I would consider adding a slightly wider low sloping roof over the front door … That would give you a spot to stick a chair or a bench … cozy to your already‑darling house.”
How to Build a Portico
A portico is a covered entrance to a building, often with columns or other ornamental structures. As a building element, it is found in classical architecture, neoclassical architecture and Roman architecture. Some 19th-century English-language sources use the term porte-cochère for a roofed area between the exterior door of a building and the main entrance at which its carriage stops.
The word portico comes from Latin porricus meaning “doorway” and corresponds to the same etymology as the English word porch. The Italian word for portico is controfacciata
Porticos are sometimes topped with pediments or parapets (as in the image above), but this is not always the case. In modern usage, a portico may be applied to:
a porch-like structure on buildings such as offices, schools or hotels; it may also be called an “arcade”, if columns are used;
a loggia or veranda;
a small shelter on wheels used in rural areas as an open-air cafe;
A portico is a covered entrance to your home that shelters you from the sun, rain and wind. They are often built with columns, but there are other ways to build them as well.
A portico can be built in many different ways. The most common way is to have brick pillars with an overhang sheltering your entryway. This is the easiest way to build a portico, but it is not the only one. You can also use wood or even stone if you want something more permanent or decorative.
If you are looking for an easy way to add some style to your home, then consider adding a portico on the front of it. This will give your house a more elegant look and make it easier for people to find when they come looking for you. It will also give them a place where they can sit down while they wait for someone inside the house so they don’t have to stand outside in bad weather conditions all day long waiting for someone inside the house who may or may not be coming out soon enough for them because we all know how long people like taking before coming out once someone knocks on their door so we are
