I'm building a shed for bikes, and it's going to be short and wide with double doors. Each door will nearly be square - about h1000mm x w900m. Can I build ledged and braced doors with only two ledges and one brace between them? As the height of the doors is so short it seems excessive to have three ledges and it makes the angle of the braces very tight. I'm not very knowledgeable so feel free to state obvious things
