Building fireplace

[Tonythecat]

I'm just about to start bricking up to create new enclosure for inset stove pic shows roughly where bricks will be and trowel is were stove will eventually be positioned. The base is concrete but needs raising up by about 30mm which I planned to screed with grit sand and cement. Question is should I brick up and then apply the screed or screed the whole area and build onto the screed. Thanks in advance

Potentially you could do either, it's up to you. The downside is that if ever you decide to hack the floor up, the brick structure may be damaged with it.
