DIY Mosquito-Proof Veranda | Build It with Aluminum Profiles 2026

Building a DIY veranda can be a fantastic idea, both because it extends the livability of a space and because making it yourself with aluminum is certainly cheaper than having a custom one made by an installer.

DIY Mosquito-Proof Veranda

In the warm season, anyone with a garden, terrace, or porch can enjoy some cool air without leaving home, but the pleasure is often disturbed by mosquitoes. In some areas, like where our reader Fabrizio Marni lives, there are really a lot of them, and defending your spaces is not easy.

The portico of his home is large enough to be used in summer as a dining area or relaxation space, but a solution was needed to protect this area without implementing actual closures and without major expenses. Hence the idea of creating a DIY veranda with metal profiles that would support frames covered with mosquito netting, letting light and air through but not insects.

Which Aluminum Profiles to Use for the DIY Veranda

For the box sections, galvanized profiles for drywall of 50×50 mm are used, available in 3-meter bars and easily cut to the required lengths. The frames are made with 25×25 mm section strips, and the aluminum mosquito netting is available in 1000 and 800 mm widths. To hold them in place, L-shaped metal brackets of 30×30 mm are needed, also for drywall. The frames with the mosquito nets of the DIY veranda can be easily removed at the end of the season; the structure is also designed for disassembly, with a bit more work. While you're at it, consider browsing our home improvement collection for additional tools and materials.

How Long and How Much Does It Cost to Build a DIY Veranda?

Using his spare time, our reader took two and a half months to complete the project. The total cost was around €400, including all materials and the aluminum mosquito netting. To keep your outdoor space comfortable in cooler evenings, you might also look at our outdoor heating options.

How to Build a DIY Veranda

The construction process involves measuring the area, cutting the aluminum profiles to size, assembling the frame with brackets, and attaching the mosquito netting to the frames. Each frame is then fitted into the main structure. For a polished look, add some outdoor lighting to illuminate your new space.

How to Install a Cat Flap in the DIY Veranda

To install a cat flap, simply cut an opening in one of the mosquito net frames and mount the flap according to the manufacturer's instructions. Reinforce the edges with additional aluminum strips to maintain structure integrity. For more storage solutions for your tools and supplies, explore our sheds collection.
