How about a coffee table book on interior design and architecture? Some options could be "The Architecture of Happiness" by Alain de Botton, "ReDesign: The Art of Sustainable Interior Design" by Sabrina Soto or "Elements of Style: Designing a Home & a Life" by Erin Gates. Alternatively, you can buy him a gift card for a local home decor store or a consultation with an interior designer to give him some inspiration for his own space.
Or you can get him a star map with the date when he was born.
