Three UK: Case Study

Moving House …

Drivers

1. New Baby.

2. Old house.

3. Not set up for the future

growth of our family.

The Future

1. New build.

2. Efficient, built on latest

standards.

3. Big enough for our growing

family.

Moving House …

Reality!

1. We needed to move furniture, clothes & valuables

room by room.

4. Move the kids to a new school.

3. Change address and payment info for gas, electricity,

water.

2. Change our address at the bank, driving license, IDs,

Passports … etc.

And I thought that this is all I needed to do ! Until …

1. My son had to make new friends

2. He needed to get used to the new school bus.

3. He needed to get used to the new house!

We have made great progress! But still in transition
