The Providence Baptist Church building and its 2.7-acre site at the intersection of International Drive and Leesburg Pike in Tysons Corner is being sold to Linpro Co., a Philadelphia-based developer with a local office in Germantown.

Linpro will pay an undisclosed sum for the church building and grounds and provide a six- to seven-acre replacement site for the church about 2 1/2 miles west of Tysons Corner at the intersection of Leesburg Pike, Lewinsville Road and Brook Road, according to Linpro's operating partner, R. William Hard, and the chairman of the church's building committee, Eugene Strange.

Neither would reveal the sale price, but several Tysons area commercial real estate brokers estimated that the site is worth at least $3.4 million. One broker said that, depending on the agreements in the deal and exactly how Linpro proceeds to develop it, the land could be worth as much as $5 million. One developer said he would not even guess the value of the site.

Hard said Linpro plans to build an office building on the site, and expects next spring to ask that the site be rezoned from residential to commercial use. "We will seek a high-density office building. We will go for height, but it won't be a megastructure" because of the size of the site, Hard explained. Some of the parking will have to be underground. Hard said "we will be aiming for a corporate-headquarters type of building."

The sale ends years of speculation about whether the church would remain in the middle of the busy, commercial Tysons Corner area and, if the congregation chose to move, who would end up developing the site.

"We wanted to be in Tysons," Hard said. "The location is outstanding. Being next to a regional mall offers all the amenities you can't get at other sites." The church site is adjacent to the Tysons Corner shopping center and close to the planned mammoth mixed-use Tysons II complex.

Hard and Strange said the contract between the church and Linpro is complicated. It contains several contingencies, including the rezoning of the present church site and the issuance of a special-use permit to permit construction of the new church building on the replacement site, which is across Brook Road from an existing church.

The contract also calls for Providence Church to continue to hold services at its present building until the new facilities are completed.

Linpro does not expect to have its office building ready for occupancy until late in 1988.

Members of the church plan to meet with residents of the Lewinsville Road-Woodside area and other nearby neighborhoods as soon as their development plans are completed. The present congregation numbers more than 600. "We want to build a facility that is a complement to the neighborhood," Strange said.

A private school on a portion of the proposed new site for the church will continue operating there through the end of the 1985-86 school year, Hard said.

In Northern Virginia, Linpro owns a totally leased two-building office park along the Dulles Road corridor in Reston known as Linpro Park II. Four buildings, totaling 450,000 square feet, are under construction by Linpro at Commonwealth Corporate Center in Fairfax City near I-66 and Route 123. In addition, a 24-acre office park to be known as Enterprise Business Park is in the planning stages along Route 28 south of Route 50, according to Hard.

Linpro completed Lakeside, a 137,000-square-foot office facility adjacent to Lake Forest mall in Montgomery County in 1983. That building is leased entirely to International Business Machines Corp., Hard said.
