10W is loud, probably too loud to crank at home, but not enough for playing in a band, especially a loud band. You probably want something in the region of 25-50W.
The problem here is that I'd consider building high gain, high output amps as an advanced skill, and it takes a lot of time, money and enthusiasm to get to the point where you can make an amp at that level that works and sounds good.
You could do an low-medium gain, low-medium output AX84 project or another project amp from around the web, study up and then build the big amp as your second or third amp, but it's an expensive way to go. Perhaps build a more intermediate level one with a medium-high gain preamp but low output which you could still use for practice/recording even after you've built the big gigging amp, then at least that's better value for money, but the learning curve is steep. You'd have to seriously study a lot of theory to make up for not having built a beginner level amp first.
Start off by learning your basic electrics (voltage, current, Ohms' law, Kirchoff's laws, resistors, capacitors, inductors, transformers, diodes etc.), then study valve amp design ( [link] is a good starting point, along with the AX84 P1 theory document, red them all the way through). Get to the point where you can break down and explain every subcircuit and every part in the AX84 schematics. For high gain, study layout in particular, as the higher the gain, the easier it is to bozo the layout and cause positive feedback which might sound like a microphone next to a speaker for example.
However, if you just want a generic metal tone the same as everyone else and don't want to spend a ton on it, you're probably best off buying a commercial 50W Marshall, Peavy, Mesa Boogie etc. (N.B. Although I say the tone is generic, I wouldn't say they sound bad, the designers are pretty knowledgable experienced and have a decent budget for design)
