The visitor welcome centre, phase 1, will be located in-between the West Block and the Centre Block. You may note a large excavation in that area right now. That excavation is specifically for phase 1 of the visitor welcome centre. You will enter essentially from the east into the visitor welcome centre, phase 1, which will provide security screening before entering the West Block, as well as visitor greeting services.
When the Centre Block undergoes rehabilitation, the visitor welcome centre will be expanded to connect underground with the Centre Block and the West Block. So the visitor welcome centre will be largely underground and will provide a secure screening before entering into the main Parliament Buildings.
