Understanding the Extension Process
Initial Consultation & Free Design Offer
We begin with a home or video visit to understand goals, budget, and timeline. Choose KT5 Constructions as your builder and we’ll include free architectural/structural design to get your scheme moving from day one.
Planning & Permission
We handle permitted development checks, planning applications, party wall coordination, and building control approvals—streamlining the paperwork so you don’t have to. (Many Brent homes can benefit from permitted development, though conservation or Article 4 areas may require full planning—our team will advise.)
Construction & Project Management
Your dedicated site manager coordinates trades, inspections, and quality checks—from foundations and structure to electrics, plumbing, and finishes—so your extension is delivered safely, neatly, and to the highest standard.

Frequently Asked Questions
How much does a Brent house extension cost?
Costs vary by size, design, access, and specification. As a guide:
-
£1,800–£2,500 per m² for standard builds
-
£2,800+ per m² for high-spec finishes
We provide fixed pricing and can phase works to suit your budget.
Do I need planning permission for an extension in Brent?
Many single-storey rear or side extensions fall under permitted development if they meet specific limits. Homes in conservation areas or with previous alterations may require full planning. We’ll confirm the route and manage the application where needed.
How long does an extension take?
A typical single-storey extension takes ~10–16 weeks on site once approvals are in place; double-storey or complex schemes can take longer. We’ll set a clear programme with milestones before work begins.
