Why it was refused
- The proposed side extension, by virtue of its scale, design and finishes, would result in an insensitive and incongruous form of development that would fail to respect the character and appearance of the existing dwelling and the wider area. The proposal would therefore be contrary to Policy SW11 of the Merthyr Tydfil County Borough Council Replacement Local Development Plan.
From the council's decision notice.
