mbhplc.co.uk

Michelmersh is the UK's premium clay brick specialist, and its site is a genuinely useful specification resource for architects and designers — think BIM objects, EPDs, CPD talks, swatchbooks, and a façade designer gallery all in one place. It's a manufacturer site rather than an editorial one, but for anyone detailing brick façades it earns a bookmark.

aram.co.uk

Aram is a long-standing London retailer and trade supplier of authorised modern designer furniture and lighting, stocking names like Eames, Saarinen, Artemide and Flos. Useful when you need a trustworthy UK source for specified pieces rather than a reference archive — think purchase, not inspiration.
