I've just been getting some thoughts on a design for my website, now it's several years since I've done anything like this (nearly 10) and this is a very early version, but thoughts so far? It's only a mockup in photoshop at the moment.

Definitely a good start.It is very minimalist (not a bad thing) but there's a few things I'd iron out:
I'd tie the header and nav to the far right to keep your right margin consistent.
It looks a bit odd having the horizontal bar, the image and the disclaimer tied to the far right and then the title and nav inset slightly.
Alternatively bring the horizontal bar back in like with the end of the title/nav.
Similarly, the horizontal bar just 'stops' on the left. It's not tied to anything and looks 'floaty'. I'd either take it the full width to align with the left edge of the body copy or bring it in to the left-hand-side of the main image.
On a similar note, the social-media icons are inset slightly from the left edge of the body copy.
With regard to the title, the K of '.co.uk' isn't aligned to the T of 'contact' and I'd probably shift it down slightly so that it's got equal vertical space between the title, the line and the nav.
If you're going to go so drastically minimal, these little things make all the difference. You could introduce a few little devices like keylines to make everything look connected.
I know the body copy is only a placeholder but you really shouldn't use hyphenation.
The only other thing I would say is that the footer bar is very strong in black, it's fighting with the image for attention on such a muted-grey page. Maybe tone it down slightly (75% black) or introduce a single strong colour (magenta/cyan/green) etc to give it all some character.
Have you thought about rollovers for the nav and any other hyperlinks? What will they do?
I know it's a 'first draft' so I hope you don't think I'm being too critical.![]()
