I appointed AC Design Solutions for a challenging new build project - demolishing an existing house and replacing it with 7 new flats in Isleworth. The team provided a comprehensive service including architectural design, structural engineering calculations, building regulations drawings, and preparation of all the technical reports required for planning (drainage, energy, daylight/sunlight, arboricultural, etc.). The project was taken to Hounslow Planning Committee and we achieved unanimous approval on the first attempt. AC Design Solutions were very responsive throughout, handled all the pre-application consultations, and prepared a strong case that addressed all the planning concerns. Their knowledge of local planning policies and building regulations was excellent, and they coordinated all the specialist consultants we needed. The building regulations drawings were detailed and compliant, ready for submission. I would highly recommend AC Design Solutions for residential development projects in West London. Really pleased to have these guys on my team - they are absolutely on the ball, and I look forward to doing many more projects with them in expansion of my portfolio.

Had a great experience with AC Design, the customer service was great and they responded to our questions promptly. Turnaround for designs were quick too. I especially appreciated having a call with the engineer as it helped us understand why the designs were constructed in a certain way. Highly recommend this company if you require structural drawings done

STRUCTURAL STEEL DESIGN - RESIDENTIAL STRUCTURAL ENGINEER FOR A NEW BUILD

ARCHITECTURAL SERVICES & DESIGN

Architectural Design Services From Brief to Planning Permission

Our approach to design starts with listening. We take time to understand each client's needs before we draw a single line. Whether you want to create your dream home, convert a commercial building into flats, or develop a new-build scheme, we provide design solutions that balance your vision with planning policy, structural reality, and build cost.

We design buildings and spaces that work efficiently, look right in their setting, and perform to modern standards. Every scheme goes through rigorous review against local planning policy before submission so the design lands well with the authority — not just on screen.

Feasibility Studies and Concept Design

Before committing to a full architectural project, a feasibility study tells you what is realistically achievable on your site. We assess planning constraints, permitted development rights, structural implications, and indicative build costs so you can make an informed decision.

This early-stage advice saves homeowners and developers significant time and money before any design fees are committed.

Home Extension Architecture

A home extension project is one of the most effective home improvement investments in the London domestic market. We design single-storey rear extensions, double-storey side returns, and wrap-around layouts, creating new space that improves everyday living while adding measurable property value.

Every design respects the existing character of the building and the streetscape requirements of the local authority.

Initial Consultation and Site Survey

Every project starts with a free consultation. We discuss goals, budget, and timescale. Next, we carry out a laser-measured site survey to record every detail. This accurate base ensures smooth design and planning and precise construction drawings later.

FAQ

Do I need an architectural designer or can I draw plans myself?

You can submit your own plans. However, most councils expect professional architectural drawings showing compliance with current standards.

Working with an experienced London design consultancy improves accuracy and approval rates significantly — and reduces the risk of costly amendments after submission.

How long does the architectural process take?

Concept design: 2–3 weeks

Planning drawings: 1–2 weeks

Planning determination: 8–13 weeks

Building Regulation drawings: 2–3 weeks

Building Control approval: 5–10 days

Fast-track services are available for time-sensitive projects.

What is the difference between planning permission and building regulations?

Planning permission looks at design, size, and neighbourhood impact. Building regulations cover structure, safety, and insulation.

Our architectural services manage both so your building work stays compliant at every stage from initial concept through to completion on site.

Can you work with my builder?

Yes. We work with your chosen builder or recommend trusted construction specialists who understand our drawings and can price accurately from our detailed set of documents.

What information do you need to start?

Property address and ownership details
Outline of requirements and budget
Existing drawings or surveys
Photos of current conditions
We can arrange missing information through our architectural consultancy services.

When are building regulations required for my project?

Building regulations are required for most building projects, including extensions and loft conversions, structural alterations, new builds and major renovations, installing new windows or doors, electrical work and plumbing installations, garage conversions, and any work affecting fire safety or structural integrity.

Some minor works may be exempt  our team can assess your specific project and advise whether obtaining building regulations approval is needed.
