It should also be noted that take-up in Bristol's out of town market reached 425,000 sq ft, 34% above the 10-year average. This was largely driven by Babcock signing for 86,000 sq ft at 100 Bristol Business Park during the final quarter.
Enquiries remain robust in the Bristol market, and we expect take-up to reach c.600,000 sq ft during 2018, 10% above the 10-year annual average.
A record £756 million of venture capital investment took place in the South West office market during 2017, over double the previous annual record in 2015. Venture capital investment provides an indication of latent office demand in the sub 5,000 sq ft market, which we expect will gather momentum through this year.
Grade A supply in the city centre now stands at only 119,000 sq ft, enough for only around nine months of Grade A take-up at average levels. One of the challenges for the Bristol market during 2018 will be the shortage of options for occupiers, who may be forced to re-gear.
Top rents in the city centre jumped a massive 14% to £32.50 per sq ft during 2017. Given £32.50 per sq ft was achieved on comprehensively refurbished product, this provides even more scope for rental growth on new build schemes. We expect top rents to grow further in 2018 and 2019, representing unprecedented growth over a three-year period.
With Aurora scheduled to complete at end Q2 2018 and now factored into our Grade A availability schedule, there is now no further speculative development in Bristol city centre. Refurbished schemes including Unum House and the second phase of Programme will deliver a combined 80,000 sq ft of space.
Given this structural shortage of space, we expect developers to commit to speculative schemes in the city centre by the end of Q1 2018. AXA's Assembly, Bristol (below) could be one of the next schemes to commence development. With consent for up to 300,000 sq ft of office space, the buildings could be delivered by 2020, by which time, the Grade A market will become even more stretched.
Engine Shed 2 is likely to provide additional incubator space to startups, following the success of Engine Shed. Glassfields would also provide c.90,000 sq ft of space across three buildings on 5,000- 6,000 sq ft floorplates and provide for the medium sized operators in Bristol, who are particularly short of options.
