‘The determination of the size of the building is based on the disposition of the furniture as it is needed for the liturgical use and therefore, above all, the place of the altar has a central place in it.

The height of the altar is precisely based on the average body length of a human being who is standing behind the altar. This height lies in between 95 and 100 cm. If this measurement is taken as the smallest measurement of the main block with its proportions of 3 : 4 : 5^{1/3}, then the measurements of the top surface are maximum 175 cm x 132 cm, which fits well with the liturgical use. In that connection the ‘planum’ is 7/4 times as wide, meaning + 3 metres.’

3 : 4 : 5^{1/3 }is the elementary block. Al sides relate as 3:4.

The height of the altar then is about 100 cm.

‘Between the choir benches and the ‘planum’ a zone of approximately 2 metres is required, so the distance between the choir benches becomes 7 metres. The double rows of the choir benches on both sides of the altar have to be 6 metres together. The unit then becomes 13 metres wide.’

The total width of the gallery is 2/9th of the total width of the church, which means that the galleries together occupy 3/7th and leave a part of 4/7th. The total width of the church becomes 7/4 x 14 = 24 1⁄2 metres.’

‘To end up with a surface area of 3 by 7 metres the church needs a total length of 54 metres, a length that has been maintained throughout the entire building.

The ordinance of the entire building can now be explained systematically through this largest measure.

According to a length of 54 metres, there is a width of 23,20 metres.’

‘Of that area of 54 to 23,20 metres a third part is being taken for the atrium with size 23,20 x 17,50 metres.’

17,50 m : 23,20 m = 3:4

‘The width of the gallery at the head receives a third of the width of the atrium, which is 5,70 metres.’

‘For the length of the actual hall 30,80 metres remains, that is 4/7 of the total length of the building.’

30,80 m : 54,00 m = 4:7

‘The galleries, which occupy a width of 2/9th of the total width of the building are thus 4,90 wide and leave up 13,40 for the width of the nave.

Because in length and width 3/7th of the total measure has been subtracted by the atrium and the galleries, the hall has a surface of the same proportion as the entire building: 3:7.’

13,40 m : 30,80 m = 3:7

‘On the short sides of the atrium the galleries are as wide as those of the church itself, which is 2/9 of the length of the atrium; but on the long sides the galleries are smaller, 1⁄4 of the width of the atrium, that is 4,30 metres.’

‘These galleries on the long side of the atrium leave a width of 8,90 metres between them, a little more than 8,60, the derived of 10,00 metres and 2/3rd of 13,20 metres.’
