Mexican firm Intersticial Arquitectura has built a home on the outskirts of Querétaro, using local materials such as light-coloured bricks, rough masonry blocks, and an exposed concrete frame. Casa Zirahuen is a 350-square-metre residence built on a deep, narrow plot. The two-storey building encompasses four bedrooms, and is named after the street it is built
Add cap blocks to the top row of a block or stone retaining wall. You can add a layer of masonry adhesive to hold them in place, then back fill. Or you can backfill as you go, then add the cap. Either way, it provides a nice finished look, much like edging added to a paver patio.
