Frequently Asked Questions//
1. What services do Archico provide?
We offer a full range of residential and commercial architectural services, including measured surveys, concept design, planning applications, building regulations drawings, 3D visualisations, project coordination, and support through construction to completion.
2. Do I need planning permission for my project?
This depends on the type and scale of your proposal. Many home extensions and alterations fall under Permitted Development not requiring a planning application. There are also other PD options such as agricultural to residential conversions under Class Q, though all new builds require formal planning approval. We can assess your property and advise the most suitable route before starting the design.
3. How long does the planning process take?
Local authorities typically take 8–10 weeks to decide on a planning application, though times can vary depending on your council and the complexity of your project.
4. What is the difference between Planning Permission and Building Regulations?
Planning Permission deals with the appearance, size, and impact of your project on the surrounding area.
Building Regulations ensure the build meets safety, structural, energy-efficiency, fire, and accessibility standards. Most projects require both.
5. How much do your architectural services cost?
Costs vary depending on the size and complexity of the project. We provide transparent, fixed-fee quotations after an initial consultation so you know exactly what to expect before proceeding.
6. Can you help if my planning application has been refused?
Yes. We can review the refusal, advise on how to address the council’s concerns, and prepare a revised application or appeal if appropriate.
7. Do you offer site visits and measured surveys?
Absolutely. we offer a free initial consultation, and every proceeding project begins with a detailed measured survey so that all drawings are accurate and compliant with planning and building requirements.
8. Can Archico manage the entire project from start to finish?
Yes. We can provide support from early concept design through planning, building regulations, tendering, and coordination with builders and engineers during construction all the way to completion.
9. Do you provide 3D visuals or virtual walkthroughs?
Yes. We offer 3D renders and models to help you visualise the design before any work begins. This is especially helpful for homeowners making layout or interior decisions. All our works are developed via a 3D software platform.
10. How do I get started?
Simply contact us through our contact form or directly via telephone or our design@archico.co.uk email address to book a free initial consultation. We’ll discuss your ideas, outline the process, and provide a tailored proposal for your project.
