Voorschoten began as a ribbon village on an ancient beach ridge, with the long Voorstraat as its market street. In 1934 it had almost 5,500 residents; today it has close to 26,000, and most of that growth came after the war. So new window frames in Voorschoten usually go into a home that is part of a terrace or a neighbourhood with its own character.
For centuries the same road has linked Voorschoten and Wassenaar: the Papeweg, then the Lange Kerkdam, then the Langstraat. Our showroom is on that last stretch, where we go through your plans and compare profiles, colours and glass with you.
According to the municipal design guidelines (welstandsnota), most of the housing dates from the boom years of the 1950s and 1960s: mainly terraced houses and walk-up flats on a straight grid. In Vlietwijk, extensions, cladding and mixed colours have gradually worn away the original unity of the rows, and new frames can bring some of that calm back.
The older 1930s extensions have terraced and semi-detached houses in earth-toned brick, with red tiled roofs, bay windows and dormers. Here everything comes down to proportion: a new frame follows the lines and divisions of the old one, or the look of the whole row changes.
In the neighbourhoods built after 1970 the question shifts from preservation to comfort: more glass towards the garden or water, better insulation and a front door that closes properly.
From the protected village centre to the new homes along the Vliet.
The historic heart, with its lime trees, village pump and gas lamps, is a protected conservation area. The facades form a closed row of individual buildings with tall windows and brick arches with keystones. The design guidelines rule out uPVC here.
Bloemenwijk, from the 1930s, lies between Papelaan and Wijngaardenlaan, the old roads to Wassenaar. Krimwijk follows the Krimkade with five side streets. Both have terraced and semi-detached houses with bay windows, dormers and details such as gutter brackets (gootklossen).
Neighbourhoods from 1950 to 1970 with plenty of public green. Vlietwijk has terraced houses and four-storey walk-up flats; Boschgeest, next to open countryside and Rosenburgh cemetery, also has semi-detached homes and bungalows.
Noord-Hofland, up against Leiden, got its first houses in the late 1960s and grew mainly in the 1970s, with flats, terraced houses and linked homes. Bijdorp, between the Kerkvaart and the Vliet, is full of water, and many of its homes back straight onto it.
Starrenburg was built from the 1990s, with detached houses on its edges looking out over the Vliet and the polder, and along the old ribbon road the Oud Woelwijck farmhouse, a national monument. Krimwijk II has been built since 2006 on former greenhouse land along the Vliet.
The Voorstraat is a protected conservation area, and most of the countryside belongs to the Landgoederenzone (estates zone) designated by the state in 2007. Plans are still assessed against the 2008 design guidelines. We check this for your address and tell you honestly if uPVC or aluminium will not work there.
Transom lights, glazing bars (roeden) and the balance between fixed and opening sections define these houses. We carry that layout over, for instance with tilt-and-turn windows under a fixed transom, or a French casement (stolpraam) without a fixed central post.
Choose from 144 panel designs in uPVC or aluminium and 9 colours, woodgrain included, with a side light left, right or both, a straight or arched transom, letterbox, glazing bars and clear or frosted glass. If you wish, add SKG-certified RC2 hardware, multi-point locking or a smart lock.
Many homes in Bijdorp and Krimwijk II sit on the water. A lift-and-slide door or double French doors (tuindeuren) with side lights bring that view inside; the more fixed glass, the better the price per m².

Our showroom at Langstraat 52a is 4 km from Voorschoten as the crow flies. You are welcome from Tuesday to Saturday, 10:00-17:00, no appointment needed. To be sure an adviser is free, call or WhatsApp +31 6 41 50 36 42 first. We speak Dutch, English and Polish.
We measure up for free anywhere in Voorschoten, and within 24 hours you have a quote listing frame, glass and installation separately. Our own team installs on a fixed date, takes the old material away, finishes inside and out and stays close by for aftercare.
Probably not. For the Voorstraat and its surroundings, the 2008 design guidelines call for traditional facade materials and state that uPVC is not permitted. We check what is allowed for your building and tell you honestly if our range does not fit.
Yes, if you want it to. We record the old layout and carry it over, transom and glazing bars included. If the appearance of the facade stays the same, a permit is usually not needed.
Yes, you choose the colour per side. Besides white and cream white there are ten other colours, such as anthracite RAL 7016 and fir green, plus Golden Oak and Notenhout woodgrain. Each coloured or woodgrain side adds about 16%.
If your glazing qualifies for the ISDE subsidy, we help with the application. Triple glazing (HR+++) with warm-edge spacers insulates best and costs about € 90 per m² more than HR++.
