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.

Our Process

Type of loft conversion services

Dormer loft conversion
Mansard
Hip to gable
L-shaped loft
House extension

Dormer loft conversion

Our dormer loft conversion service creates additional headroom and floor space by extending your roof outward. Dormer loft designs maximise your usable space while maintaining your property’s character. We provide complete drawings and planning services for both front and rear dormer conversions.

Mansard loft conversion

Mansard loft conversion projects involve altering your roof slope to create maximum space. Mansard loft designs typically require planning permission but offer the greatest space increase. Our mansard specialists create plans that blend seamlessly with your existing architecture.

Hip to gable loft conversion

Hip to gable conversions transform sloping roof sections into vertical walls, significantly increasing floor area. Hip to gable loft designs are popular for semi-detached properties and require expert drawing and planning to ensure structural integrity.

L-shaped loft conversions

L-shaped loft conversions work perfectly for properties with complex roof layouts. Our architects in London specialize in creating innovative architectural designs that turn your ideas into practical, beautiful spaces.

House extension alternatives

When considering house extension options, loft conversion often provides better value than ground floor extensions. Extension or conversion decisions depend on your specific needs, but loft extension projects typically cost less and cause less disruption than traditional house extension plans.
