[1] Mylne learned his trade from his father, assisting him with projects including the sundial at Holyrood Palace.

The Tron was built to house the congregation of St Giles', which had been raised to cathedral status, and was laid out in the new T-plan form with the pulpit in the centre, to suit reformed worship.

[5] From 1643 to 1659, he served as master mason for the construction of Heriot's Hospital (now a school), succeeding William Aytoun.

[7] Projects in the 1650s included the building of fortifications in Leith, and the addition of artillery emplacements to Edinburgh's town wall.

[8] He undertook the division of Greyfriars Kirk, so that it could serve two congregations, and constructed a professor's house for Edinburgh University, which was demolished in the 18th century.

[1] Following the Restoration of Charles II, Mylne was reconfirmed in his post of Royal Master Mason, and was commissioned in 1663 to survey the upper floors of Holyrood Palace.

The resulting plans are the earliest surviving architectural drawings from Scotland, and are held in the Bodleian Library in Oxford.

[10] This house, demolished in 1950, resembled Heriot's Hospital and other Scottish 17th-century buildings, rather than looking forward to the new classical styles which would be introduced by Bruce.

[11] Mylne's architectural works are in the Scottish Renaissance tradition, which combined gothic and classical elements, together with mannerist ornament, often derived from imported pattern books.

He was buried in Greyfriars Kirkyard, Edinburgh, where a monument, erected by his nephew and apprentice Robert Mylne, still stands.
