What Affects the Cost?

Extension costs in Bishopbriggs are influenced by several key factors: the size and complexity of the design, choice of materials (brick, render, cladding), foundation type and ground conditions, whether the extension is single or two-storey, access to the site, local planning and building regulations requirements, and availability of skilled labour in the area. Ground preparation, existing structure condition, and proximity to utilities also impact final pricing. Single-storey extensions typically cost less per square metre than two-storey additions due to reduced structural complexity.

Money-Saving Tips

Plan your extension during quieter building seasons (autumn/winter) to negotiate better rates. Obtain multiple quotes from different local builders to compare pricing. Consider simpler designs with standard materials rather than bespoke features, and ensure you factor in building regulations and any required structural engineer fees upfront.

Frequently Asked Questions

What's included in an extension builder's quote?
A comprehensive quote should include labour, materials, groundworks, foundations, structural elements, roof, windows, doors, insulation, plastering, and basic decoration. Always clarify what's excluded—such as specialist finishes, landscaping, or electrical/plumbing upgrades—before committing.
How long does a typical extension take in Bishopbriggs?
A single-storey extension usually takes 12–16 weeks, whilst two-storey projects typically require 20–28 weeks. Weather, building control inspections, and material delays can extend timescales. Always ask your builder for a detailed project schedule.
Do I need planning permission and building regulations approval?
Most extensions require building regulations approval, though some permitted development rights apply in Scotland. Planning permission depends on size, location, and design. Your builder should advise, but it's wise to check with East Dunbartonshire Council or consult a surveyor beforehand.
What's the cost difference between single and two-storey extensions?
Two-storey extensions typically cost 40–60% more per square metre than single-storey due to additional structural requirements, foundations, and complexity. A 40m² single-storey might cost £48–72k, whilst a comparable two-storey could reach £108–150k depending on specification.
