I've got a potential customer who has a bedroom with sliding glass doors that sit 5' above grade. She wants a brick patio flush with the door sill. This patio also needs to have a staircase that'll take her to grade level. Has anyone worked with handrails in retaining wall block? I know Versa-Lok engineers aren't wild about the idea, having a piece of metal (for example) mounted into a flexible wall. But I also know I'm not interested in building this person a 'lover's leap' patio.
