This site is powered by the excellent Kirby CMS.
It was developed using Mark Perkins' 'Elf' development environment, using Sass, Grunt and coded in Sublime. All images have been optimised using JPEGMini or ImageOptim.
The early design explorations were done using the wonderful Sketch app, and the site is typeset with (gasp!) three fonts: OverPass, Oswald and Neuton. The first is a lovely open source font found at overpassfont.org and the latter two are found on the Google Webfonts platform.
