Re: Aircon cover / BBQ stand - Custom bench for apartment balcony
Welcome to the Bunnings Workshop community @Aishjadhuni. It's wonderful that you've joined us, and many thanks for your question on this brilliant project.
At a minimum, it appears you would need a handsaw or circular saw and a drill driver. There is no reason why you couldn't use exterior PVA glue, but you'll also need to fix the legs to the top with screws. Nails are an option instead of screws if you didn't have a drill driver, but using screws will probably be easier for you.
Hopefully, @DoSimpleBetter will be able to provide further details on their project for you.
Please let me know if you need any assistance or have further questions. I can't wait to see your finished air-con cover.
