Off cuts of blue XPS foam for the rough shape, then sculptamold to fill in the gaps and cover the foam, balsa frame for the bunkers, bit of cheapo filler for gaps then, sand bags made from Milliput.
PVA over the sculptamold and a sprinkling of fine sand, then painted with Artiste acrylics (Amazon about £1.50 for a 59ml/2 oz pot). Light drybrush with Vallejo 'Dark Sand' & some washes and pigments ( a very thin watery wash).
Unfortunatly I didn't take many WIP pictures. Made four 'trench' sections, three with Bunkers; a mortat pit, howitzer emplacement, a couple of open ended trench pieces; a gate, an ammo storage thing and a watch tower.
