The buildings of Weesp are characterized by deep houses. These often not basement houses are often raised later. The house Middenstraat 42 has early-15th-century side walls and is a remnant of the refectory of the Young Convent, which was largely demolished after 1577 (built 1397-1427). The capped late-16th-century shoulder façade of Slijkstraat 1 has wall anchors, checkered relief arches and masonry decoration with crosses and windows. Most old houses in the city center are of a younger date.
17th and 18th century houses
From the double house Drosthagen (Middenstraat 9-11) the linked spout façades from 1665 (facing brick) were renewed in 1885 while retaining three bricks (Faith, Hope and Love). Owner of the gin distillery established around 1700 was notary Cornelis Drosthagen. Hoogstraat 9-10 has 17th-century lion masks and a facing brick. The bell-gable at Hoogstraat 47 was renovated at the end of the 18th century, but preserving the old sandstone decorations and festoons (circa 1670). Also 17th-century are Hoogstraat 33-34, with banderole-facing brick dated '1675', and the spout facade of Hoogstraat 60. It was possible in the core 17th-century building Slijkstraat 44 (facing brick '1668') around 1860 a block plastering. The transverse single-layer building De Gouden Reaal (Kerkstraat 13, 1697) was also plastered later on.
Many facades were renewed in the 18th century. For example, Nieuwstraat 21 and 33 spout facades with a top crown and Nieuwstraat 50 were given a spout façade with the coat of arms of Amsterdam. An upstairs room and interesting dormer windows has the transverse single-layer building Nieuwstraat 34 (1710; dormers 1820). Richer in shape are the bell-gables with natural stone corners and segmented crowns of Binnenveer 11 (circa 1750) and Slijkstraat 28, and the neck facade of Hoogstraat 28. Later on, the 18th-century house Hoogstraat 21 (1756, older facing bricks) was plastered. In respect of 18th century, but possibly with an older core, the plastered deep house Breedstraat 25 with high roof. The underlying business area (Achtergracht 79) served as a brewery. Nice door frames have Buitenveer 58, Hoogstraat 48 (late 18th century) and Nieuwstad 90 (circa 1800). The stately mansions built as burners' houses Het Grote Plein 1-3 and 2-4 are large eighteenth-century transverse buildings that together form the square in front of the town hall. Other, in the core, eighteenth-century dwarf houses are Nieuwstad 14-16 and 18 and the Nieuwstad 126-136 residential row.
19th and 20th century houses
In the second half of the 19th century, when the urban economy was once again attracted, many existing houses were given a new simple list facade, such as Nieuwstraat 13. The house Vita Nova (Hoogstraat 62, circa 1830) has a cornice with carved consoles and a beautiful framed entrance. The possibly 18th century mansion Hoogstraat 24 in 1866 was given a new, basement, front house and a neoclassical façade with high pavement and sober pronkrisaliet. This building served as a town hall from Weesperkarspel from 1924 to the abolition of that municipality in 1966. The three-storey mansion Buitenveer 54-56 (circa 1840) was converted into two separate houses around 1880.
Many façades were plastered with false joints and new doors and windows. This can be seen, for example, at Slijkstraat 31 (circa 1860) and Kerkstraat 17 (circa 1870, with door frame). Achtergracht 78 has a screen facade for the floor (circa 1870). From the 18th century house Hoogstraat 35 the front part around 1860 in neo-classic style was renewed and raised with a mezzanine. Eclectic details show the plastered large corner building Het Grote Plein 5 (circa 1880). Eclectic elements also have the façade of Slijkstraat 9 (circa 1885) with an embossed stone substructure. The facade of Buitenveer 42 (circa 1890) has plastered bacon layers. Such neo-Renaissance elements appear in yellow brick at Herengracht 18 (residence with practice) and in cement stone at Nieuwstad 34.
Examples of completely new sober and stately neoclassical mansions dating from around 1870 are Herensingel 11-13 and Oudegracht 23-25. In 1876, near the station, the Amsterdam Houses (Herensingel 15-37) were erected, six connected upper and lower houses in eclectic style. The neoclassical style house Stationsweg 19 (circa 1890) is equipped with checkered pilasters and a dormer window with chalet-style wind springs. Poort van Weesp (Buitenveer 60) was renewed in 1895. Exceptionally large is the Villa Casparus (Korte Stammerdijk 13), built in 1897-'99 to a neo-Renaissance design by A. Salm for C (asparus) .J. van Houten, son of the founder of the Van Houtenfabriek. This manufacturer's villa, which has been converted into apartments, has staggered building elements with bay windows and a loggia (garden side). The part remains of the garden layout designed by L. A. Springer
