## Summary
Splitting a 2-bed maisonette in Thornton Heath into a studio and a 1-bed flat. Dismissed. The inspector found the loss of a home under 130 sq m (protected by Croydon DM1.2) contrary to HO7 as well, and found the remote cycle and refuse stores contrary to TR4 and DP3. With a five-year supply agreed, one net unit had limited weight and was substantially outweighed under S4 (DL ¶28-30).

## What made the difference
The inspector read HO7 as supporting a local policy that protects existing mid-sized homes. Weak cycle and bin access added national-policy conflicts, which made the S4 balance straightforward. Parking was not a problem.

## Policy findings
- **HO7: conflict.** loss of a 74.85 sq m home, protected by local DM1.2 (under 130 sq m), also treated as contrary to HO7 (DL 8-11)
- **TR4: fail.** cycle store reachable only via street and rear alley; discourages cycling (TR4, DP3) (DL 13-15)
- **S4(1): fail.** net one extra unit (limited weight) substantially outweighed by loss of small home and poor cycle and refuse storage (substantial weight) (DL 27-30)

## Key facts
- Five-year supply agreed
- Existing 2-bed of 74.85 sq m lost to two smaller units
