Life could be quite difficult in the early years of the colony. Many colonists lived in fairly crude structures, including dugouts, wigwams, and dirt-floor huts made using wattle and daub construction. Construction improved in later years, and houses began to be sheathed in clapboard, with thatch or plank roofs and wooden chimneys. Wealthier individuals would extend their house by adding a leanto on the back, which allowed a larger kitchen (possibly with a brick or stone chimney including an oven), additional rooms, and a sleeping loft. These houses were the precursors to what is now called the saltbox style of architecture. Interiors became more elaborate in later years, with plaster walls, wainscoting, and potentially expensive turned woodwork in the most expensive homes.
