THE surfer-wear fashion house Billabong signed on for a store at 112 W. 34th St. opposite Macy’s in Herald Square.

“Herald Square is sizzling,” said Jeffrey Roseman of Newmark Knight Frank Retail, who, with Paul Berkman, represented the tenant in the pact.

Joanne Podell of Cushman & Wakefield handled the work for W&H Properties on the 1,587-foot store, which is being carved out of the building’s large lobby. Sources said the average rent over the life of the 10-year deal works out to $630 a foot.

“We thought about what was a good image and a good user, and we thought Billabong was fashionable and not outrageous, and its quality offering was very appealing,” said Anthony Malkin, president of W&H Properties, who checked out Billabong’s Times Square store.

The Phillips Group is the architect for the new contemporary lobby that will have an undulating ceiling. New bathrooms, hallways and renovation of the curtain wall are also in the works for the original Zeckendorf-developed Childrenswear Building that, until recently, had been managed by Helmsley Spear. Office rents, which now range from the high $30s to mid-$40s, are expected to rise with the redo.

Complicating every company’s search is that the next wave of large new office towers won’t be ready until at least 2010, pushing up rents in all building classes. And you thought your office rent was expensive now?
