What to Expect: The Architectural Process from Concept to Completion

Embarking on a home extension, loft conversion, or new build in London is an exciting journey—but understanding the architectural process is essential for a smooth, successful project. At NFA Architecture, we guide clients through every stage, from initial ideas to the moment you step into your transformed space. Here’s what you can expect at each step of the architectural process, tailored for London homeowners seeking clarity, value, and peace of mind.

1. Initial Consultation & Brief Development

Every project starts with a conversation
We listen to your vision, goals, budget, and timeline. This is your opportunity to share your Wishlist, ask questions, and discuss any site-specific challenges. We’ll explain our process, outline potential services, and help you understand what’s achievable within planning and budgetary constraints.

Key outcomes:

• Clarified project goals and requirements

• Site visit and feasibility assessment

• Early advice on planning permission and regulations

2. Feasibility Study & Strategic Brief

Before diving into design, we conduct a feasibility study. This includes:

• Reviewing site conditions and local planning policies

• Identifying potential constraints or opportunities

• Outlining project scope and assembling the right team (e.g., structural engineers)

The result is a strategic brief—your project’s roadmap, ensuring everyone is aligned before design begins.

3. Concept Design

Here, your ideas start to take shape. We develop initial design concepts, often using:

• 2D and 3D drawings

• Mood boards and precedent images

• Early sketches and layout options

You’ll see how your new space could look and function. We’ll discuss materials, sustainability, and how to maximise light, space, and value. This stage is highly collaborative, with feedback shaping the evolving design.

4. Developed Design

Once a concept is agreed, we refine it into a detailed, coordinated design:

• Floor plans, elevations, and sections

• Integration of structural and mechanical elements

• Virtual walkthroughs or visualisations

We ensure the design meets building regulations and is ready for planning submission. At this point, we may seek pre-application advice from the local authority to smooth the planning process.

5. Planning Permission & Regulatory Approvals

Securing planning permission is a crucial milestone for most London projects. NFA Architecture manages:

• Preparation and submission of all planning documents

• Liaison with planning officers and local authorities

• Amendments or negotiations as required

We also advise on party wall matters, build-over agreements, and any conservation area or listed building considerations.

6. Technical Design & Building Regulations

With planning approval in hand, we prepare a technical design package:

• Detailed construction drawings and specifications

• Structural calculations (often in-house)

• Building regulations compliance documentation

These documents are essential for accurate contractor pricing and for building control sign-off—crucial for property value and future sales.

7. Tendering & Contractor Selection

We help you find the right builder by:

• Issuing tender packages to vetted contractors

• Comparing quotes and clarifying inclusions

• Advising on contract terms and timelines

Our goal is to secure competitive pricing and ensure your chosen contractor can deliver to our standards.

8. Construction & Contract Administration

With contracts signed, construction begins. NFA Architecture remains involved to:

• Conduct regular site visits and monitor progress

• Answer builder queries and resolve issues

• Certify payments and ensure work aligns with drawings

We act as your advocate, ensuring quality, safety, and compliance throughout the build.

9. Handover & Project Completion

As construction concludes, we:

• Inspect the finished work and compile a snagging list

• Ensure all building control certificates and warranties are provided

• Guide you through the handover process

We’re available for post-completion support and to address any final concerns, ensuring you’re delighted with your new space.
