The organisation, run by Abe Hayeem, has published a half-page petition in The Times opposing three major projects which, it argues, symbolise Israel's 'unethical' seizure of Palestinian land.
The petition urges Israeli architects and planners to reject involvement in the design and construction of projects at Silwan, Ma'ale Adumim and Lifta, which it claims will result in the illegal destruction of Palestinian communities.
The fresh assault comes weeks after APJP announced it was considering calling for an economic boycott of Israel's construction industry.
APJP states: 'We call on the Israeli Association of United Architects to adhere to the UIA codes of conduct, and end the participation of their members and fellow professionals in creating 'facts on the ground' to obliterate the idea of a viable future Palestinian state.'
It adds: 'APJP asserts that the actions of Israeli architects and planners working in conjunction with this enterprise are unethical and contravene professional codes of conduct and UIA codes.'
