Lets start with the lounge. Click on the 'Furniture' button.
Scroll down to the bottom of the following dialog, click on the 'TV' symbol icon at the end of the 'Misc' group.
Now select the 'Furniture' button again. You will notice that the dialog is automatically scrolled to the position when the last symbol was selected. Now scroll to the 'Sofas' group and click on 'Sofa 1' as shown below and then 'Insert'.
Continue to insert the various furniture items as shown in the ground floor layout. All of the 'Lounge' and 'Dining' items used are found in the Furniture library.
All of the 'W.C.' items used are found in the Sanitary library. All of the 'Kitchen' and 'Utility' items used are found in the Kitchen library.
Sometimes depending upon the insertion point it is not possible to achieve the desired position first time. You may have to place the symbol approximately and use the Move command to position the symbol.
The Kitchen work surfaces were added simply using the Line command.
