Alvari & Pers is an interior design studio working on private homes. This journal is where the studio writes down the parts of the job that clients ask about most: how colour and light behave in a real room, which materials age well, and how a plan is arranged so the room actually works. No project galleries, no trend lists.
When commissioning a room scheme, agree the drawings, revisions and purchasing responsibilities first. This overview of how interior designers charge in the UK helps a UK client compare appointment scopes.

A high rub count does not guarantee a durable sofa. A sound upholstery specification also checks the test method, weave, fiber blend, pilling grade, lightfastness and permitted cleaning process.
