(Elswoutslaan 20). This country estate was founded in 1654 by cloth merchant Carel Molijn (or du Moulin). After purchase in 1781, Jacob Boreel had a new house built. The current 'Grand House', executed in the style of a 16th-century Italian Renaissance villa, is a square three-tiered building with porch porch, flat roof with attic and a central hall with a light dome. The construction of this house began in 1883 according to a design by C. Muysken for W. Borski III, but was discontinued after his death in 1884. It was not until 1940 that the Germans completed the building, which was then converted into a military command post. After the war it is Jac. P. Thijsselyceum and de Zocherschool were established in the building and after vacancy since 1992 it was converted into an office in 2004-'06. On the east and west side is a large terrace with steps steps, on the west side bordering a pond party and on the east side on a meadow.
To the forecourt on the south side of the house a brick arch bridge, built around 1806, leads to plans by B.W.H. Ziesenis (modified circa 1882). From around 1654 the U-shaped one-storey gatehouse (Elswoutslaan 12) with a roof rider, as well as the two coach houses with stable (Elswoutslaan 16-18) and the oldest part of the lockkeeper's house (Elswoutslaan 10) date back.
The park layout still contains elements of the 17th-century geometric landscaping, such as the pruned linden lane or parasol lane on the east side. Between 1781 and 1794 Jacob Boreel had an early-landscape construction made according to Johan Georg Michael's plans. In doing so, use was made of the differences in level created by sanding, and a number of sand docks were taken in the construction during the northward extension of the park. In the first half of the 19th century, the park was built according to plans by J.D. Zocher sr. And jr. Modified and upholstered with all kinds of small buildings, such as the illusionistic 'Kabuur' house, a reed covered rustic garden house (in the Camp), a pheasant residence, a hermitage and a neo-Gothic wooden garden house. On the east side a deer camp was constructed with a deer house with a thatched roof built from wooden trunks. In addition, several bridges were built, including three Swiss (wooden) bridges. In 1883 further changes in the park construction followed plans by C.E.A. Petzold.
An eclectic design by C. Muysken is the orangery (Elswoutslaan 22, circa 1885) with domed roof, arcade with ionic columns, lower side wings and then a semicircular greenhouse or greenhouse. The chalet-style model farm 'Elswout' (Elswoutslaan 24, circa 1885) is also designed by Muysken. In front of the farm there is a potato storage room (after 1812) and to the west an early 19th-century ice cellar, for which B.W.H. Ziesenis made a first design in 1805. In the park the cast iron sculpture group 'Halali' is depicted on a stone pedestal, depicting a hunting master with two dogs (1888, after the original model by H.M.A. Jacquemart). The form is outside the park. steward's house (Duinvlietspad 2), a white plastered building from 1847 with a higher middle party and veranda, and the plastered house Duinvlietspad 4 (circa 1875).
