Where is the announcement being made? [originaltext]Welcome ladies and gentlemen

Welcome ladies and gentlemen!(86)| am glad to take all of you on a tour of our head office.(87)We are proud to reveal to you the result of more than 5 months of planning and 10 months of remodeling.
For our customers’ convenience, our main lobby area has been expanded to create a more spacious environment. Many thanks are due to famous sculptors who donated their sculptures to our company for lobby decorations. Also, the building elevators have been rebuilt for faster travel between floors. Finally,(88)we have redecorated the exterior of the premises with the addition of the most technologically advanced windows, which not only reduce UV rays, but also protect occupants in the building from excessive heat or cold.
