At the time of the dedication, only the sanctuary section of the church was built and amber glass filled the spaces where art glass was planned for future installation. The stained glass windows were installed and dedicated in April 1928. They were designed and crafted by the Tyrolese Art Glass company (Tyroler Glasmalerei Anstalt) founded in 1861 in Innsbruck, Austria. The company is still in existence. ​ Ground was broken for construction of the north wing closest to Westwood School on June 7, 1935. Joseph Steinkamp was the architect. The last wing was added in 1957 to the south and west of the original structure. It includes the lower level dining room and current administrative offices. The Westwood First Presbyterian Church congregation has been an active member of the community all these many years through various ministries and committees and clubs such as Boy Scout Troup 107, which was authorized in November 1922 and is still sponsored by the church. The church's music ministry has been an important part of their culture and since 1981, they have offered the popular Westwood First Concert Series, featuring a wide range of local, national, and international performers of all genres.
