Build Your Own Smokehouse Guide

Understanding Smokehouse Basics and Types

A smokehouse is a structure designed to cook and preserve meat, fish, and other foods using smoke from burning wood. The smoke comes from wood fires, and the heat and smoke slowly cook the food while giving it flavor. Smokehouses have been used for centuries across many cultures as a way to preserve meat without refrigeration and to create unique tastes that people enjoy.

There are several main types of smokehouses you can build, each with different benefits. A vertical smokehouse is tall and narrow, which makes efficient use of space and allows smoke to rise naturally through the chamber. A horizontal smokehouse is wider and longer, giving you more cooking surface area. A drum smoker is built from a steel drum and is portable and affordable. An offset firebox smoker has a separate chamber where the fire burns, and smoke travels into the cooking chamber, which gives you better temperature control. A pit smoker is dug into the ground and uses the earth for insulation.

The size of your smokehouse depends on how much food you want to cook at once and how much space you have available. Small smokehouses can handle 20 to 50 pounds of meat, while larger ones can accommodate several hundred pounds. Consider whether you want to smoke small batches regularly or larger quantities less often.

Practical takeaway: Before building, decide which type fits your space, budget, and smoking goals. A drum smoker is cheapest and easiest to build. A horizontal smoker gives the most cooking space. An offset firebox gives the best temperature control for longer smoking sessions.

Materials and Tools You Will Need

Building a smokehouse requires materials that can withstand heat and moisture without rust or deterioration. The main structural materials include wood framing, metal drums or barrels, concrete blocks, or steel. If you choose wood, use species that resist rot, such as cedar or treated lumber. Metal components must be food-grade stainless steel or high-temperature steel that won't rust when exposed to smoke and moisture.

For a basic drum smoker, you will need one 55-gallon steel drum, grates for holding food, thermometers, vents or dampers to control airflow, and a door mechanism. The drum should be clean and food-safe. For a brick or block smokehouse, you will need cinder blocks or brick, mortar, sand, metal grating, and concrete for the foundation.

Essential tools for construction include a drill, saw, level, measuring tape, wrench set, thermometer, metal file, wire brush, and safety equipment like gloves and eye protection. If building a permanent structure, you may want a concrete mixer and shovel for foundation work.

The materials cost for a basic drum smoker ranges from $150 to $400, depending on the quality of grates and thermometers. A brick smokehouse can cost $500 to $2,000 depending on size and whether you do the work yourself. Horizontal barrel smokers typically cost $300 to $800 in materials.

Practical takeaway: Start with a materials list based on your chosen design. Collect all items before beginning construction. Buy high-quality thermometers and vents—these affect smoking results more than expensive materials. Check local building supply stores for used food-grade drums, which cost less than new ones.

Site Selection and Foundation Preparation

Choosing the right location for your smokehouse affects how well it works and how safe it is. Place your smokehouse in a spot that gets good air circulation so smoke disperses and doesn't accumulate around people or structures. Position it at least 10 feet away from buildings, fences, and overhanging branches to reduce fire risk. Make sure the location has good drainage so water doesn't pool around the structure, which causes rust and wood rot.

The ground should be level or nearly level. If your site slopes, you will need to do some grading to create a flat surface. A sloped surface makes it difficult to keep food level during cooking and can cause smoke to escape unevenly. Check that the area gets some shade during the hottest part of the day if you live in a very hot climate, as this helps maintain consistent smoking temperatures.

Prepare the foundation based on your smokehouse type. For a permanent brick or block structure, pour a concrete foundation 12 inches deep and 4 inches thick. Dig the holes for foundation posts if using a wooden frame. For a drum smoker, create a level pad from gravel or concrete. If building in clay or wet soil, add gravel underneath to improve drainage.

Consider wind direction and prevailing breezes when positioning your smokehouse. If wind consistently blows from one direction, position the intake vents on that side so wind naturally draws smoke through the chamber. This reduces the amount of fuel needed and improves smoke distribution.

Practical takeaway: Mark your location with string and check it at different times of day to observe sun and shade patterns. Clear away leaves, dead wood, and other debris. Create a level base using a simple level tool. Test water drainage by pouring water on the area after rain to see where it flows.

Building the Smokehouse Structure

The construction process varies depending on which type you choose. For a drum smoker, start by preparing the 55-gallon drum. Clean it thoroughly inside and out with a wire brush to remove rust and debris. If the drum has a lid, keep it. If not, you can fabricate one from sheet metal. Cut a door opening on one side, large enough to load meat comfortably but small enough to maintain temperature. The door should be about 12 by 14 inches. Use a metal file to smooth the cut edges.

Install the grates inside the drum. Most people install two or three grates spaced 8 to 10 inches apart. Support the grates on metal rods welded or bolted to the drum interior, or use adjustable grate hangers. Grates should be sturdy enough to hold 50 pounds of meat without bending. Mount a thermometer through the drum wall at the level of the top grate so you can read the temperature from outside.

Create the firebox chamber below the lowest grate. You can build this by installing a metal box on the bottom of the drum, or by creating a chamber from the drum itself if you keep the bottom intact. Install a metal pipe or tube to carry smoke from the firebox to the cooking chamber. Make sure this pipe slopes slightly upward so condensation drains back toward the firebox.

For a brick or block smokehouse, lay the foundation, then begin stacking blocks or brick with mortar. Leave small gaps (called flues) between some blocks to allow smoke to rise naturally. Build the walls 6 feet tall for comfortable working height. Install a grate or metal platform inside to hold food. Build a peaked roof to shed water, and install a chimney opening at the top.

Practical takeaway: Take time to ensure doors fit properly and close securely, as gaps waste heat and smoke. Mount thermometers at food level, not at the top of the chamber where temperature may be higher. Test all seams and joints with smoke before loading meat to find and seal any large leaks.

Installing Vents, Dampers, and Temperature Control

Temperature control is the key to successful smoking, and proper venting makes this possible. Every smokehouse needs intake vents to bring fresh air and oxygen to the fire, and exhaust vents to let smoke escape. The intake vents should be near the bottom or firebox area, and the exhaust vent should be at the top of the chamber or chimney. This creates natural airflow called a draft.

Dampers are doors or valves that control how much air flows through the vents. An intake damper near the firebox controls how fast the wood burns and how much heat the fire produces. An exhaust damper at the top controls how much smoke and heat leave the chamber. By adjusting these dampers, you control the internal temperature. Most smokers can reach 225 to 275 degrees Fahrenheit with proper damper adjustment.

Install dampers that are easy to reach and adjust while smoking. Butterfly dampers (round discs that rotate) are simple and effective. Ball valve dampers work well but cost more. Make sure damper openings are at least 2 inches in diameter so you have enough airflow for the fire to burn properly. If vents are too small, the fire smolders and produces too much acrid smoke.

Mount accurate thermometers at the level where food sits
