The J.C. Schmidt/K.B. Blank organ (1813/1966) of the Gereformeerde Kerk in Boven-Hardinxveld was modified and enlarged during Spring 2012. The organ case is hereby expanded to include two additional fields to accommodate the enlarged pedal. The Positive received new pipe work in a better scaling as the existing pipe work made by Blank did not blend well with the original Smitdt pipe work.   

Just a few months after the restoration of the Flentrop organ (1976) was completed by Van den Heuvel,  the contract was awarded to construct the Fagot 32'. The resonators and the booths are made from mahogany.  
The photo shows the test setup in the workshop. The inaugural concert took place on the traditional Queensbirthday organ recital 2012. Arjen Leistra, the main organist of the Great- or St. Janskerk performed the opening concert.

The Leeflang organ (18IIP, 1963) recieved a re-voicing. In the original configuration a major part of the stops were not used because their sound experience was unpleasant. Besides the re-voicing some stops were changed (Hoofdwerk chamade Trumpet and Mixture composition) or replaced (Sharp and Rugwerk Tertiaan). A more carrying and milder sound was achieved, special attention was given to the aggressive speech of the principals and mixture. Acting consultant was Wietse Meinardi. January 27 at 20:00 as the organ will be officially taken into (re)use.

In 2010 a number of renowned organbuilders were asked to bid for a major overhaul, restoration and expansion of this Flentrop organ (1976). After examination and comparison, the contract was awarded to J.L. van den Heuvel Orgelbouw.
In the period January-April 2011, the following works were executed:

• cleaning and restoration of all pipes,
• partial re-voicing,
• installation of new wind concucts for display pipes and offset pipes,
• installation of additional walkboards,
• checking of the key- and stop action,
• stabilization of the historic display pipes
• installation of an additional (independent) wind supply for the pedal, consisting of two folding bellows and two windmotors, placed under the wind chests of the pedal.
• extension of the pedal division with a Prestant 16', aRoerquint 12' (from mahogany wood) and a reservation for a Fagot 32'. Two new slider wind chests were installed behind the excisting organ case.

For the Fagot 32' a fundraising action started and a few months after the inaugural concert on April 30th 2011 by Arjen Leistra the contract for this additional stop was awarded to Van den Heuvel.
