It seems we are not the only ones in love with this prehistoric mollusc. The architect and clients for this groundbreaking build based their entire house around a fibonacci series or golden curve inspired by an ammonite found on their land. A numerical fibonacci series is where each number is the total of the previous two, 1, 2, 3, 5, 8, 13, 21 etc and this sequence is seen in growth patterns throughout the natural world, from ferns to pine cones to shells to our favourite fossil, the ammonite.
Grand Designs followed what turned out to be challenging technical build. Designing the house around the golden curve meant that every roof beam was a different size, the outer walls were curved and there were no straight lines from foundations to roof trusses. Even the roof covering (my least favourite bit) was all hand cut. The ammonite inspiration was for me visible until they roof cladding was added at which point the house began to look like a snake coiled up in the landscape which I really didn't like but the inside is wonderful. The programme is available on catch-up https://www.granddesigns.tv/blackdown-hills/ and is well worth a look.
