Planning Applications in Hammersmith & Fulham (LBHF)

What homeowners need to know before submitting — and after approval

Planning permission in Hammersmith & Fulham (LBHF) is often seen as the main hurdle in a refurbishment project. In reality, it is only one part of a wider decision framework that includes structural design, Building Control, landlord consent (for flats), and cost sequencing.

Understanding how LBHF approaches residential planning applications can materially reduce delay, redesign and avoidable cost exposure.

How LBHF Typically Reviews Residential Applications

LBHF planning officers tend to focus on:

Scale and massing of extensions
Impact on neighbouring properties
Overlooking and privacy
Roofline alterations and dormer proportions
Materials and external appearance
Conservation area considerations

This is particularly relevant in: Fulham, Parsons Green, Brook Green, Imperial Wharf, Hammersmith, and Conservation areas along the Thames

Common Residential Planning Scenarios in LBHF

Loft Extensions and Roof Alterations

In LBHF, rear dormers are common, but ridge height increases and roof terraces often receive greater scrutiny.

Common issues:

Oversized dormers
Increased ridge height
Overlooking from roof terraces
Obscure glazing conditions

Even if planning is approved, conditions may alter design detail.

Rear Extensions

Single and double-storey rear extensions are typical across the borough.

Key sensitivities:

Depth of extension
Impact on neighbours
Materials in conservation areas
Basement and rear lightwell visibility

Basement Excavations

Basements require particular care due to:

Structural impact
Party wall implications
Drainage and flood considerations
Construction logistics

These projects often involve multiple layers of approval beyond planning.

Planning Approval, LBHF project sequence, & Conservation Areas

What Planning Approval Does Not Cover

This is where many homeowners misunderstand the process. Planning permission from LBHF does not:

Approve structural design
Confirm Building Regulation compliance
Override lease obligations
Remove the need for party wall agreements
Guarantee cost certainty

Planning is a design and policy approval, not a technical or commercial one.

The Typical Sequence in LBHF Projects

A structured sequence should look like:

Concept design
Pre-application discussion (if required)
Planning submission
Structural engineering development
Building Control submission
Contractor pricing based on mature scope
Formal appointments

In practice, many projects jump from step 3 to step 6 too quickly.

Conservation Areas in Hammersmith & Fulham

Large parts of LBHF fall within conservation areas. This affects:

Window replacements
Materials
Roof alterations
External façade changes

Homeowners often underestimate how conservation status alters design flexibility.

Leaseholder Properties and Typical risks in LBHF

Leasehold Properties in LBHF

If the property is leasehold:

Planning permission does not replace landlord consent
Additional drawings may be required
Surveyor review may be triggered
Structural warranties may be requested

This is particularly relevant for flats in mansion blocks and converted houses.

Typical Cost Risks in LBHF Refurbishments

In our experience, avoidable cost exposure often arises from:

Pricing before structural detail is final
Underestimating fire compliance upgrades
Ignoring drainage constraints
Assuming landlord consent is administrative
Treating planning approval as final clarity

These risks can amount to 15–30% of total project cost in some cases.

Where Independent Advisory Support Helps

We provide independent advice to help homeowners:

Structure decisions before committing
Understand planning vs compliance distinctions
Identify cost drivers early
Review scope maturity before procurement
Sequence design and pricing logically

We do not design or build — we help ensure decisions are properly structured.
