What makes Fetcham Special?
Architects in Fetcham therefore have to work hard in designing new buildings that should be modern but functional while at the same time giving a rural look. Restrictions placed on the green belt in particular require solutions that are environmental hence making the projects here technically challenging and environmentally sustainable.
The homes themselves can look very traditional, although there are more and more cases of using classic designs with modern energy-saving features. This balance between innovation and the preservation of nature is what makes Fetcham so desirable to individuals interested in living in a home that is in harmony with its environment, yet provides all the amenities of the contemporary world. Moreover, the fact that the community has never relented in its pursuit to preserve the green belt aesthetics contributes to its desirability.
- 1930s semis and detached homes dominate KT22 — ideal for rear and loft projects.
- Green Belt and protected land restrict development — full planning is usually required.
- Strong local demand means well-designed extensions consistently add lasting property value.
- Mole Valley Council works to a clear 8-week householder planning decision timeline.
