Spoiler

    Area areapt = new Area(2955, 3226, 2950, 3221);
     private void doLarder() throws InterruptedException {
            RS2Object Larder = getObjects().closest("Larder space");
            RS2Object Portalf = getObjects().closest(15478);
            RS2Object Larder2 = getObjects().closest("Larder");
            RS2Widget Oak = getWidgets().getWidgetContainingText("Oak larder");
            if(!getMap().isInHouse() && areapt.contains(myPlayer().getPosition()) && Portalf.hasAction("Build mode") &&  Portalf.isVisible() && getInventory().getAmount("Oak plank") >= ? {
                Portalf.interact("Build mode");
                new ConditionalSleep (5000, 500) {
                    @Override
                    public boolean condition() {
                        return areapt.contains(myPlayer().getPosition());
                }
            }.sleep();
            }if(getMap().isInHouse() && !Larder.isVisible() && !myPlayer().isAnimating()) {
                getWalking().walk(Larder);
            } if (Larder.isVisible() && !myPlayer().isAnimating()) {
                Larder.interact("Build"); sleep(random(400,700));
                new ConditionalSleep (5000, 500) {
                    @Override
                    public boolean condition() {
                        return Oak.isVisible();
                }
            }.sleep();
             if(Oak.isVisible() || Oak != null  ) {
                getKeyboard().typeString("2"); log("building");
                new ConditionalSleep (5000, 500) {
                    @Override
                    public boolean condition() {
                        return !myPlayer().isAnimating();
                }
            }.sleep();
            }
     } if (Larder2.isVisible() && Larder2.hasAction("Remove")) {
         Larder2.interact("Remove"); sleep (random(600,700));
         getKeyboard().typeString("1");
     }
     }
        @Override
    public int onLoop() throws InterruptedException {
        if(skills.getStatic(Skill.CONSTRUCTION) > 33) {
            doLarder();
        }

when i build a new oak larder, this codes starts to send this logger notes and heavly lagging

You should learn some basic Java before attempting to script.

Null check the Larder 

if (Larder != null)

       // You're code

Exactly. You are first using methods on an object and are then nullchecking it for example.
