Jewelry goes on last, of course—and drapery hardware rarely leads a specifier's list. But don't tell that to the staff at Walcot House. Each design from the company's studio reads like a statement piece, certainly not an afterthought. Commanding the most attention, glass details are available in a multitude of colors.

When it comes to finials—35-plus of them, most with matching tiebacks—customers are free to create their own color combinations. Mix-and-match Moonstone finials, for example, are designed to accept round or square ornaments in 12 saturated shades. In the Beaded series, finials are bedecked in "bracelets" of either smooth or faceted beads. Beyond finials, the Universal group's curtain headings are like cuff links for the window: They're offered with both plain stainless-steel heads and, for the more adventurous, 36 colored inserts. Choice extends even to pole material: stainless steel, brushed bronze, ash, or acrylic. If all that decision-making causes any anxiety, the company offers a printed step-by-step checklist to soothe the overstimulated. 44-1993-832940; walcothouse.com.

It takes just a single open door to connect the indoors to the outside world. For a furniture designer, however, the gap between the two can be intimidating to conquer. Stefano Gallizioli shows no such trepidation with Coro's Nest collection, which is making its U.S. debut.

Refined enough for a solarium, the Nest chaise longue and accompanying side table are equally patio-worthy. If indoor-outdoor flexibility isn't enough, consider the configuration factor. Separate the two-part Circular sofa, and get a pair of lounge chairs. Or combine two Corner seats to form a chaise.

As for cushion upholstery, specify either COM or an outdoor-safe proprietary fabric that resists mildew and UV rays and comes in seven colors including cinnabar, white, and charcoal black; the filling of small foam pieces allows water to drain right through. Frames are satin-finished stainless steel. All have backs of leather (indoors) or reinforced PVC-nylon cord (out). Lepere, 212-488-7000; lepereinc.com.
