Award-Winning Design & Build for Queens Park's Victorian Properties
Queens Park has established itself as one of North West London's most desirable family areas. The neighbourhood's Victorian terraces, independent shops along Salusbury Road, and the green expanse of Queens Park itself create a village atmosphere that attracts families willing to invest in their properties. With house prices in NW6 and NW10 now well above £1 million for a terraced house, extending makes considerably more sense than moving.

- HOUSE EXTENSIONS
House Extensions in Queens Park — Victorian Terraces, Modern Open-Plan Living
Queens Park's Victorian terraces follow the classic London pattern: narrow side return, separate reception rooms, compact kitchen. The most popular extension strategy combines a side return infill with a rear extension to create the open-plan kitchen-dining space that modern families need.
Extension Types for Queens Park Properties
Side Return Extensions — The signature Queens Park extension. Infilling the side passage widens the ground floor dramatically. Cost-effective and transformative. Typical costs: £42,000 to £65,000.
Rear Extensions — Single-storey rear additions with skylights and garden doors. PD allows 3 metres for terraces. Typical costs: £50,000 to £85,000.
Wraparound Extensions — Side return plus rear for maximum ground-floor transformation. The most popular comprehensive option. Typical costs: £65,000 to £110,000.
Double-Storey Extensions — For end-of-terrace and semi-detached properties. Adds living space and bedrooms. Typical costs: £95,000 to £175,000.
What Is Included
All prices include: architecture, structural engineering, planning applications to Brent Council, all construction, project management, building control via LABC, and 10-year LABC warranty. All-inclusive quote. Call 020 8037 7332.
- LOFT CONVERSIONS
Loft Conversions in Queens Park — Adding Bedrooms to Victorian Terraces
Queens Park's Victorian terraces have steeply pitched roofs with excellent conversion potential. A rear dormer or mansard conversion adds the fourth or fifth bedroom that growing families need. Most conversions outside the Queen's Park Estate Conservation Area qualify under permitted development.
Loft Conversion Types
Rear Dormer Conversions — The most popular choice. Flat-roofed rear dormers creating spacious bedrooms with en-suites. Costs: £48,000 to £70,000.
Mansard Conversions — Maximum space for mid-terrace properties. Near-full-height rooms. Requires planning permission. Costs: £65,000 to £90,000+.
L-Shaped Dormers — For end-of-terrace properties. Rear and side combined. Costs: £58,000 to £80,000.
Hip-to-Gable — For semi-detached properties with hipped roofs. Costs: £52,000 to £75,000.
What Is Included
All prices include: architecture, structural engineering, scaffolding, all construction, staircase, insulation, electrics, en-suite plumbing, building control via LABC, project management, and 10-year LABC warranty. Call 020 8037 7332.
- RENOVATIONS
Renovations in Queens Park — Unlocking Victorian Potential
Queens Park's Victorian terraces combine attractive period features with practical renovation opportunities. Ground-floor reconfiguration, modern kitchens and bathrooms, rewiring, replumbing, and complete interior refurbishment transform the separate-room Victorian layout into the open-plan living spaces that families want.
Typical costs: kitchen renovation £26,000 to £55,000, bathroom renovation £12,000 to £26,000, structural wall removal £6,000 to £12,000, whole-house refurbishment from £90,000 upward. Detailed quotes provided. Final costs confirmed once designs and structural requirements are agreed.
- ARCHITECTURE
In-House Architecture — Brent Council Planning Experience
Queens Park falls within the London Borough of Brent. Our architects submit applications to Brent Council and understand the borough's planning policies, including the Queen's Park Estate Conservation Area's specific design requirements. The estate's unified Victorian character means proposals must respect the consistent architectural language of the original 1870s and 1880s development — a challenge that requires genuine understanding of the area's significance.
The integrated design and build model ensures buildable, accurately costed designs from the outset. For Queens Park's terraced properties, this means understanding party wall implications, structural steel requirements for open-plan ground floors, and the sequencing challenges of mid-terrace construction. Every project includes: measured survey, concept designs, 3D visualisations, construction drawings, planning applications to Brent Council, structural engineering, and building regulations via LABC. All included in your quote — no separate architect fees.
- LOCA PLANNING EXPERTISE
Planning & Local Knowledge — Queens Park
Planning Authority
Queens Park falls within the London Borough of Brent. All planning applications for NW6 and NW10 properties in the Queens Park area are submitted to Brent Council.
Queen's Park Estate Conservation Area
The Queen's Park Estate Conservation Area covers the planned Victorian estate laid out in the 1870s and 1880s. The area has a consistent architectural character with uniform terraced housing, and permitted development rights are restricted. Extensions and loft conversions visible from public areas require planning permission. Proposals must respect the estate's unified character.
Permitted Development
Outside the conservation area, standard PD rights apply. Terraced properties can extend 3 metres to the rear under PD. Rear dormer conversions within volume limits qualify. LDCs recommended.
Party Walls
Almost all Queens Park extensions involve party walls. The Party Wall etc. Act 1996 requires formal notification. We manage this as part of the project.
Typical Planning Timescales
Householder application: 8-week target. LDC: approximately 8 weeks. Building control: inspections throughout construction.
Building Control
All LCCL projects are managed through LABC building control. Inspections at each key stage ensure compliance with Building Regulations. At completion, you receive a building control completion certificate and optional 10-year LABC warranty.
