Key questions

Here are some of the most common questions before getting Habattached.

Do I need planning permission?

No! All product options will fall into permitted development (subject to listed buildings).

Does it require a specific type of foundation?

We have developed a carbon neutral foundation and floor deck system with a tried and tested supplier. This will work on all ground types and accommodate sloping and uneven situations.

Will it match/complement my existing building?

There is a choice of cladding materials that can compliment your existing house or make a statement.

What if this options doesn't fit my space?

We are afraid a ‘Hab’ is not for you. We would recommend contacting Olive & Umber and they will be able to give you options that may be more fitting for your property.

How long does it take to prep and install?

Preparation is site specific but installation of 'Hab 2' is 14/18 days.

Is the cost of install included in the price?

Yes, this is included in the cost.

What pre-work is needed? Is this part of the job or a separate cost?

The level of preparation depends on the area in which your ‘Hab' will be located. The area will need to be cleared and levels reduced if needed. This can be done by us for an additional cost or completed by yourself/local contractor.

Why choose this over traditional brick build?

It is a quicker & cleaner option with more thermal efficiency.

How long will it last?

It will have a usable life of 50 + years with a warranty of 10yrs (subject to good maintenance).

What level is it finished to?

It will be plastered and painted with full electrics ready for hard landscaping on the outside and floor coverings on the inside.
