Step through the entrance of t'Achterhuis and staff hand you a map. That detail alone tells you something important: this place is enormous. The site spans 3 hectares of rooms, yards and covered storage, all stacked with antique construction material salvaged from buildings across the Netherlands and beyond. First-time visitors often underestimate how long a thorough visit takes. Set aside a few hours at minimum.

The story behind the business is as distinctive as the stock. Founder Lambert van Alebeek was a baker by trade. Some of his clients settled their debts not in cash but in old bricks, tiles and architectural fragments. Lambert began collecting and reselling this material in 1965, treating it first as a sideline and then, seven years later, as a full profession. What started as an informal hobby grew into one of the country's most respected architectural salvage operations. The business has expanded steadily since, and the family connection has remained central to how the place runs.

Tiles are the heart of the collection. Ceramic floor tiles and natural stone floors draw the most attention, displayed in quantities that let you properly imagine them in a real space. Façade bricks fill entire sections, ranging from handmade historic formats to regional varieties that are increasingly hard to source new. Smaller decorative elements appear throughout too — ironwork fittings, corbels, terracotta details and assorted fragments that suit restoration work or standalone display. For buyers who cannot visit in person, the inventory is also available online, which makes t'Achterhuis useful even before you arrive.

Restoration work is a serious part of what happens here. The team takes on chimney restoration, saws natural stone to specification, chips and cleans reclaimed bricks, repairs furniture and ironwork, and builds kitchen tables to measure. These services put t'Achterhuis in a different category from a standard salvage yard. It functions more like a specialist workshop and supplier combined, with the skills on site to match the materials on offer.

The staff are predominantly family members with deep knowledge of the stock and long experience advising on period restoration projects. Booking an appointment before visiting is a practical step worth considering. An appointment gives staff time to walk you through the relevant sections, discuss your project in detail and point you toward material you might otherwise miss among the sheer volume of stock.

T'Achterhuis suits architects, builders, renovation specialists and private buyers working on period properties. It also draws collectors with a genuine interest in architectural history and salvage as a discipline in its own right. Few places in the Netherlands combine this scale of stock with this level of practical expertise under one roof.
