Retaining wall offset from building

[Cruezr]

Have a client who wishes to construct a timber rail/steel post retaining wall up to 1.4m high with 0.9m of a new residential building (yet to be built).
Building is located on cut side of wall, ground slopes at 25-35 deg angle above wall, natural soil condition silty clay.

Seeking some advice on how close the wall can be constructed to the building footings (mixture of slab-on-ground beams, strip footings and stump footings).
Concerned about zone of influence between wall and building for rotational resistance of retaining wall (isolated) footings.

What is the general rule of thumb on offset between wall and building in such situations (not quite like a tiered wall scenario).

If I'm reading your question correctly, I've heard that the general rule is that you want to steer clear at about 45 degrees projected outwards from the bottom of the footings in section - otherwise make sure to account for additional surcharge loading.

It sounds like you are trying to build a new building into the sloped ground surface where the building will be in front of the wall and where the ground slopes upward behind the wall. If so, the wall can be as close to the proposed building as you wish. However, you need to allow enough space between the wall and the building to allow you the build the building and, maybe, maintain the resulting area of separation between the wall and building (for possible lawn mowing, building egress, trash cleanup, etc.).
