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

What Makes Our Drawings Different

Precise Property Surveys First

We start every project with detailed measured surveys using professional equipment. Many services rely on rough measurements or existing plans – we ensure every dimension is survey-accurate before any design work begins..

Victorian & Edwardian Property Specialists

London’s period properties have unique challenges – irregular room shapes, non-standard ceiling heights, and heritage considerations. Our drawings account for these complexities that generic services often miss.

Technical Detail That Works

Our drawings show exact joist positions, beam specifications, and construction sequences. Builders get clear, unambiguous instructions that prevent costly interpretation errors during construction.

Loft Conversion FAQ

Do I need an architect for my project?

NO. Our qualified architectural technicians can handle all loft conversion projects at a fraction of traditional architect costs while maintaining professional standards and regulatory compliance for any type of conversion.

Do I need planning permission for a loft conversion?

Many planning applications aren’t needed as most loft conversion projects fall under Permitted Development rights. We assess your specific situation and advise on requirements during our initial survey, whether you’re planning a loft conversion or considering extension or conversion options.

What if my project needs building regulations approval?

Every loft conversion requires regulation drawings. We prepare these and coordinate with your building control officer until sign-off.

What will my loft conversion cost?

Your loft conversion cost depends on the property size, type of conversion, and whether it needs council approval.

Can I combine my loft conversion with an extension?

Yes. We often design loft conversions and extensions together to create larger, continuous living areas.

Is my project covered by permitted development rights?

Many are. We’ll verify if your project falls under permitted development and provide the right documents for proof.

Is my project covered by permitted development rights?

Your neighbour can’t usually stop a compliant loft conversion. If work affects a shared wall, you must serve a Party Wall Notice under the Party Wall etc. Act 1996. If they dissent, surveyors agree a Party Wall Award this doesn’t block your project but ensures it’s carried out legally and safely.
