The government should only put funding into well-designed buildings, architects say.
Sustainable housing should get stamp duty relief, says RIBA
The Royal Institute of British Architects says good architectural polices would be vote-winners.
Demanding good design will bring better public services and more sustainable communities, it claims.
The RIBA is sending its Manifesto for Architecture to parliamentary candidates when the general election is called, and to elected MPs afterwards.
The RIBA says its document, sub-titled "21 Actions for a Better Britain", has been launched after a wide-ranging consultation, which started in September.
'Power to inspire'
It sought the views of its own members, other professions and industry leaders, as well as trade unions and the public.
RIBA President George Ferguson said: "In this election year, politicians should realise that good design is essential for improving services - that's beginning to happen, but the process has been too slow, and too patchy.
"Architecture can raise our spirits and inspire us, but it also determines the quality of our hospitals, the success of our schools and the safety of our neighbourhoods."
The 21 key points include introducing stamp duty relief on the first sale of sustainable homes.
Sustainable homes are ones which are considered environmentally-friendly as well as having the proper infrastructure in place to sustain a community.
Other points include using the development of retail or leisure facilities to fund improved local transport and equipping planners with a sound understanding of design.
