Question 1

What do you need for a quotation?

Accepted Answer

We'll need the property address, architectural drawings, and structural calculations. We'll also arrange a free site visit to discuss your requirements and specifications in detail before providing a full written quotation.

Question 2

How long does a loft conversion take?

Accepted Answer

Loft conversions typically take 8-10 weeks from start to completion. More complex projects such as L-shaped or mansard conversions may take longer. We provide a clear programme of works before starting.

Question 3

How long does an extension take?

Accepted Answer

Rear extensions generally take 10-14 weeks. More complex projects such as wraparound or two-storey extensions may take longer.

Question 4

Do I need planning permission for a loft conversion or extension?

Accepted Answer

Most loft conversions and extensions fall under Permitted Development rights and do not require planning permission. However this depends on the size and scope of the work, your property type, and whether you are in a conservation area or listed building. Our architects will assess this as part of the design process.

Question 5

What insurance and warranty do you provide?

Accepted Answer

Every A-Z Builders project comes with a 10-year guarantee covering materials and workmanship. We carry Public and Products Liability insurance up to £1,000,000 and Employers Liability insurance up to £10,000,000.

Question 6

Can I live in my property during the work?

Accepted Answer

In most cases yes. Loft conversions can be carried out with minimal disruption. For extensions, structural work is undertaken from the outside first. The main consideration is the kitchen which may be temporarily out of use during interior works.

Question 7

How much does a loft conversion cost?

Accepted Answer

Loft conversions with A-Z Builders start from £45,000. The final cost depends on the type of conversion, size, and level of finish required.

How much does an extension cost?

Accepted Answer

Extensions with A-Z Builders start from £1,600 per square metre for a shell build, or from £2,500 per square metre fully finished.

Timber frame outbuildings start from £35,000. Thermalite block cavity wall outbuildings are available at a higher price point depending on size and specification.
