London Residential Project Advisory
Residential Projects, Properly Defined and Controlled
Extensions, conversions and major refurbishments often become difficult because the scope is incomplete, responsibilities are unclear or important decisions are delayed until construction has started. LeanApex helps clients establish a controlled route through feasibility, design coordination, contractor selection, delivery monitoring and handover.
Rear, Side and Wraparound Extensions
Coordination support for additional residential space, structural alterations and associated internal remodelling.
Internal Reconfiguration
Support for projects involving new layouts, structural openings, circulation changes and coordinated building-services requirements.
Selected Heritage and Complex Residential Work
Considered individually and undertaken only where the required specialist expertise and professional appointments are available.
Our service is structured around the project’s complexity, current stage, available information and the professional appointments already in place.
Projects We Support
Loft Conversions
Project-definition, design-coordination and delivery support for dormer, hip-to-gable and other suitable loft-conversion projects.
Kitchen and Ground-Floor Remodelling
Coordination of design information, contractor scope, sequencing and key decisions for integrated ground-floor projects.
Garage Conversions
Structured coordination for converting existing garage space into functional residential accommodation.
Major House Refurbishment
Structured support for extensive refurbishment involving multiple trades, technical information and staged decision-making.

Designers and Specialists

- Engineering
- Statutory and specialist advice
- Professional calculations and certifications
Contractors
- Construction methods
- Labour and materials
- Site supervision
- Health and safety duties
- Workmanship

Projects Requiring Additional Assessment
Some projects carry increased technical, statutory, financial or delivery risk. LeanApex will review these carefully before confirming whether it can accept an appointment.
- Basements and underpinning
- Listed buildings
- Higher-risk residential buildings
- Flat conversions and HMOs
- Projects with incomplete structural information
- Projects without confirmed funding
- Projects affected by active disputes
- Work that has started without adequate approvals or information
- Fixed-price construction requests based on incomplete drawings
Where a matter exceeds LeanApex’s defined competence or appointment, the appropriate response is to refer or escalate it to a suitably qualified specialist.
Preparing for the First Discussion
- Property address and project description
- Existing drawings or surveys
- Planning or Building Control information
- Indicative budget
- Intended start date
- Existing consultant appointments
- Contractor quotations already received
- Known technical, neighbour or access constraints
Complete information is not required for the first conversation. Identifying what is missing is often an important part of establishing the correct next step.
