Line up an offcut of floorboard with the architrave. Use a panel saw to trim the architrave to its height. Then, use a hammer and chisel to remove enough of the bottom of the architrave that the solid wood will fit underneath it. Be sure to leave a 10-12mm expansion gap. Once you’ve worked out how many rows of boards you’ll need, and the width of the last row, you may need to do some cutting to ensure your last row isn’t less than 60mm wide. If necessary, cut the boards in your first row accordingly so that your last row won’t be too narrow. Starting in the left-hand corner of the longest wall, use a trowel to spread adhesive from the wall to the width of two planks. Lay the first board with the groove side facing the wall. Depending on the length of the board, place one or two 10-12mm spacers along the length, and one across the width. Introduce the next board at an angle of around 20-30° and lower into place. Take great care with the alignment as it is key that your first row is perfectly straight. Add spacers to maintain an expansion gap between the board and the wall. Continue laying until you can’t lay any more full boards, ensuring the line of boards is perfectly straight....
