The finalists include RSHP and AECOM's nine-home modular housing project, built on brownfield land in Crofts Street, Cardiff, and billed as 'carbon-positive in operation'.
The other contenders are Hyde + Hyde Architects' Castle High house in Pembrokeshire; an extension to a traditional stone cottage in the Brecon Beacons National Park by Nidus Architects; and Rhossili House on the Gower coast by Maich Swift Architects.
Last year only two projects won RSAW Awards and neither scooped RIBA National Awards.
RSAW jury chair Ceri Davies, a director at Allford Hall Monaghan Morris, said: 'Each of the shortlisted projects enthused the jury with their design clarity, thoughtful material use and uncompromised execution.
'Experiencing them first-hand will no doubt prove even more uplifting, not least to appreciate how the homes feel and function – and to learn of the unique collaborations that will have inevitably shaped these exemplary projects in Wales.'
All the shortlisted projects will be assessed by a Welsh jury and the winners announced later this spring.
They will also be in the running for an RIBA National Award in recognition of their architectural excellence. The winners of the National Awards will be announced in the summer.
The shortlist for the RIBA Stirling Prize for the best building of the year in the UK will then be drawn from the RIBA National Award-winning projects, and the overall victor announced in October.
