How to Choose a Good Extension Builder in Halifax
- 1
Ask for references and photos from completed extensions — visit one if possible before appointing.
- 2
Ensure the builder handles building regulations throughout, not just the construction.
- 3
Agree a detailed programme with payment milestones before work starts — avoid large upfront payments.
- 4
Check they carry £5m+ public liability insurance for structural work.
- 5
Confirm who designs the structural elements — you may need an independent structural engineer for the design.
Frequently Asked Questions
What is the difference between permitted development and planning permission for extensions?
Permitted development allows certain extensions without a planning application, subject to limits: 3m rear extension for terraced/semi-detached, 4m for detached (or 6m/8m under the Neighbour Consultation Scheme). Anything larger, or in a conservation area, needs a planning application.
Do I need an architect for a house extension?
For straightforward extensions, an experienced builder can often manage basic design and building regulations drawings. For complex layouts, planning applications, or where you want design input on how to maximise the space, an architect or architectural designer adds real value.
How long does a house extension take?
A single-storey extension typically takes 12–16 weeks on site from start to completion. This excludes any pre-construction planning or building regulations approval, which can add several months. Double-storey and more complex projects take longer.
Will a house extension add value to my home?
In most parts of the UK, a well-executed extension adds more value than it costs to build. A kitchen-diner extension or an additional bedroom and bathroom tends to offer the strongest return on investment. Value uplift varies by location and quality of execution.
