At  AY Planning and Construction Consultants, we are a London-based planning, architectural design, and construction consultancy specialising in residential and commercial development projects across the UK capital and surrounding areas.

We provide expert guidance across all stages of the development process — from initial feasibility and planning strategy through to Building Regulations, technical design, and construction coordination.

Our approach is built on clear communication, practical design solutions, and a strong understanding of UK planning policy and Building Regulations.

Our practice is led by Ozge Tasyurdu, a qualified and experienced Architectural Technician with extensive knowledge of planning legislation, residential design, and technical construction detailing.

Under her leadership, the practice has achieved a high planning application success rate of approximately 90%, reflecting our strong understanding of planning policy, design quality expectations, and local authority decision-making across London boroughs.

Ozge brings a detail-focused and commercially aware approach to every project, ensuring that design proposals are not only creative and practical, but also strategically aligned with planning requirements and Building Regulations compliance

We are a small, highly focused consultancy with a combined team experience of over 30 years in planning, architectural design, and construction consultancy.

Our team brings together expertise in:

• Planning applications and appeals

• Building Regulations and technical design coordination

• Principal Designer services under Building Regulations

• Construction project management and site coordination

• Feasibility studies and development appraisals

This combined experience allows us to deliver a fully integrated service, ensuring continuity from concept to completion.
