MAMMOTH BUILDING MATERIALS, THE STORY BEHIND IT.

MAMMOTH OLD BUILDING MATERIALS, PASSION AND PLEASURE IN AUTHENTIC PRODUCTS AND ELEMENTS

Mammoth Old Building Materials has over 30 years of experience selling and purchasing old building materials. We started as a hobby, with our work as contractors we often found beautiful old elements that customers wanted to part with. Throwing them away was not an option for us, so we started our hobby to give these useful elements a new life with a new owner.

Because the hobby was getting out of hand, we purchased a building in 2007 in which everything could be stored and from there could go on to a new owner. From this point on, the demand for old building materials kept increasing and the building became too small.

Since 2013, we have a large inventory and beautiful showroom on Lavender Street. Father and son now run the business together. A real family business that has grown into one of the best-known specialists in selling old building materials in The Hague and surrounding areas.

Because the demand was not only high in The Hague we launched a web store in 2013, this made it possible to supply the whole of the Netherlands with old building materials! Should you be looking for something that is not found on our website? Not to worry, our offer is huge therefore it is not feasible to present everything online but you can visit our showroom in The Hague.

The large inventory on Lavender Street lives up to the name Mammoet. Mammoth specializes in old doors and stained glass. The collection includes more than 6,000. From stained glass, panel doors and sliding doors to antique fireplaces, stained glass windows and small or large building materials.

In short, a special case!

Bought room and suite doors. Very good help. We had no idea ourselves what doors were suitable and how to fix it. Received good advice and bought the perfect doors. Lots of knowledge and very helpful. We will definitely be back once we start our next project.

Top notch case! The best man knows how to find everything among incredible doors and other materials. He also has batches of the same old doors which is perfect for renovation work! If you are looking for an old door this is the place to be!

Bought panel doors from this company, huge selection and very neatly sorted. Great that they helped us on site to find the right doors plus very good advice. We also very much appreciated the help with loading. Thank you we are very happy with the beautiful panel doors! Highly recommended for everyone.
