The UK Commission for Architecture and the Built Environment (CABE) has criticised the design proposal for the new North London Tottenham Hotspur Football Club.
The authority said it disliked the building of shops and homes around the 56,000-seat stadium.
CABE said it supported the KSS-designed centrepiece stadium, but is unhappy with the wider master plan drawn up by MAKE, and the landscape design by Martha Schwartz Partners.
The proposed housing's massing is branded as eccentric and counterintuitive. CABE said it might overshadow the blocks and compromise the new flats.
The architectural treatment and materials of the blocks to the north and south of the stadium is a cause for concern, according to CABE.
The basic box form of the planned supermarket was also criticised; CABE demanded that the roof should be more carefully considered.
