Haldor Larsen Børve (19 August 1857 – 11 August 1933) was an architect from Ullensvang in Hordaland, Norway. Børve started an architectural practice in Porsgrunn in 1889 and designed numerous buildings in Telemark and Vestfold, many of them influenced by Dragestil and the Nordic National Romantic style. Among his best-known works are Dalen Hotel from 1894 and Porsgrunn City Hall from 1904/1905.
Børve was born in Ullensvang in 1857 to farmer Lars Jørgensen Børve and his wife Anna Haldorsdatter Eidnes. He attended Trondheim Technical Vocational School (Norwegian: Trondhjems Tekniske Læreanstalt) from 1877 to 1880, after which he worked for a few years as a junior architect. His only major project during this time was managing the restoration of Ullensvang Church in Ullensvang from 1883 to 1886, a project led by Bergen architect Christian Christie. In 1887, he pursued further education at the Polytechnic Institute of Hannover in Germany. He was among the last of the great Norwegian architects to attend the architectural school in Hannover, which had greatly influenced Norwegian architecture in the latter half of the 19th century. He finished his studies in 1889, and with the help of a government grant for engineers, he moved to Porsgrunn in Telemark, Norway and started his own architectural firm that same year.
