House Extensions in Norfolk Designed Around How You Live
Love where you live but feel like your home no longer works for you?
A well-designed house extension can give you the extra space you need without the cost and stress of moving. Whether you want a larger kitchen, another bedroom, better connection to the garden, or a full internal remodel, we can help.
At Ikonic Architecture, we design thoughtful house extensions across Norfolk and Suffolk that improve the way you live now and add long-term value to your home.
From first ideas to planning and building regulations, we guide you through the process in clear, plain English.

Frequently Asked Questions
Do I need planning permission for an extension?
Some extensions can be built under permitted development, but this depends on the property and location. We can advise early.
How much does a house extension cost?
Costs vary depending on size, specification, and complexity. We help you understand realistic budgets from the start.
How long does the process take?
Every project is different, but we can outline likely timescales for design, approvals, and construction.
Can I stay in my home during the build?
Often yes, depending on the type of work and how the project is phased.
Is a two-storey extension better value?
Often yes. Foundations and roof costs are spread across more floor area.
