Why it was refused
- The proposal is of poor design and would be a discordant and incongruous form of development, out of keeping with the existing dwelling and surrounding pattern of development, in conflict with Brentwood Local Plan Policy BE14 and the design objectives contained in chapter 14 of the NPPF, specifically policy DP3, which seeks to promote well designed places which respond to their context.
From the council's decision notice.
