I presume the house is TT,and the brick 'garage' with the vented door hides a substation or street switchgear and some LV fuses - it does not look like a sewage pump or a gas regulator though round here the transformers are open and the pumps are enclosed..
Is there an 11kV pole behind it ?
If it is a substation, there may be combined HV and LV earth or they may be separate. There is perhaps a chance of putting a rod in the garden of the house near the boundary and getting an impedance near that of TN-S .
I'd be asking How far does the house extend the other way - any electrode to be placed nearer the other neighbour may be prudent.
