I helped my Dad build a fire pit in his garden, he made wooden seats to sit around the metal fire pit with old stone columns for extra seating (unfortunately you can't see the actual fire-pit as behind the stone bench). Lots of stories and fun are had around it until deep into the night. If you have the space it is a great addition to put in! Shannon

Wow that is an amazing garden and view. A pergola is a good idea to add a feature but for a more serviceable structure you could opt for a patio roof or garden roof. These aluminium roofs contain fully automated louvres so you can control whether your relaxation space is sunny of shaded depending on the day. Another plus for the UK is that these roofs become watertight when the louvres are flat so you can use your outdoor space, and appreciate that view no matter the weather.

Not sure if you have now sorted out your garden lighting yet I've only just come across your question! But if you haven't yet then you could definitely do as you have suggested already and have some decking lighting, some examples of such you can find here as there are also many decking light kits to choose from. http://www.thebulbco.com/outdoor-led-lights/led-ground-lights/led-decking-lights For something different to think about for wall lighting, why not think about getting some in wall brick lights for something a little bit unusual perhaps http://www.thebulbco.com/outdoor-led-lights/led-ground-lights/outdoor-brick-lights Hope this helps a little but would be good to see some of your finished photos once you have them to hand to see what you decided on!

Hi Simon I mainly do kit fire pits but also undertake bespoke projects. Please feel free to contact me if you still wish some advice.
