Lay a metre wide gravel path down the back garden for approximately 50 metres

Rear garden patio. I want two sections of grey Indian sandstone patio to fill two areas where hedges have been removed (it’s soil edged with loose engineering bricks). The sections are 7.50m x 0.90m & 6.20m x 1.20m Next to each section is an existing path 6.2m x 0.56m of slabs in a line that I would like some lifted & mixed into to the new, so it doesn’t look odd. Pointing isn’t required...

Rectifying an existing front pathway (essentially replacing as the mix is in a constant state of deterioration) and build a low 3 course wall
