Home and Building Extensions in Wembley — Design, Plan and Build
Moving house is expensive and disruptive. Extending your current home is often the smarter option — adding the space you need without the stamp duty, legal fees and upheaval of a move. At HighPoint Roofing and Building, we design and build home extensions across Wembley, Harrow, Ealing and the wider area, managing the full process from initial concept through to handover.

Types of Extension We Build
We have been building extensions on Wembley properties since 2010, backed by over 50 years of combined trade experience across our team. Our builders, bricklayers and roofers work together daily, which means your project is coordinated efficiently without the delays and miscommunications that come from relying on separate subcontractors.
Kitchen Extensions
Kitchen extensions are the single most common project we undertake. Wembley homes — particularly the 1930s semis and post-war terraces — often have kitchens designed for a different era. We offer a complete service including kitchen design and fitting, plumbing and electrics, tiling and flooring installation.
Rear and Side Extensions
Rear extensions extend into the garden, while side extensions make use of the narrow passage alongside many semi-detached and detached homes. Side return extensions are particularly effective on terraced properties in Wembley, reclaiming dead space to widen the kitchen or living room.
Wrap-Around Extensions
A wrap-around extension combines a rear and side extension into a single L-shaped or U-shaped structure. This is the most ambitious extension type and delivers the greatest gain in floor area, well suited to detached and corner-plot properties in Wembley.
Planning Permission in Wembley
Many extensions in Wembley fall within permitted development rights, which means they do not require a formal planning application. This generally applies to single-storey rear extensions up to certain size limits, subject to conditions around height, proximity to boundaries and materials.
When Planning Permission Is Required
- Your property is a flat or maisonette
- Your home is a listed building
- Your property is in a conservation area
- The proposed extension exceeds permitted development size limits
- The extension significantly affects the appearance of your property
- Double-storey extensions (usually require planning permission)
We handle the entire planning process — from preparing drawings and design statements to submitting the application and liaising with the local authority. We will also tell you honestly at the outset whether your proposal is likely to gain approval.
Do I Need Planning Permission in Wembley?
Many single-storey rear extensions fall within permitted development rights, which means you may not need planning permission at all. However, this depends on your property type, location, and the extension’s size and design. Our experts will assess your specific situation during the initial consultation and guide you through any necessary planning applications.

Popular Extension Types in Wembley
We offer a range of extension options to suit different property types and homeowner needs in Wembley. Whether you need general building work or a complete extension, our experienced team will help you choose the perfect solution for your home.
Single-Storey Extensions
The most popular extension type in Wembley. A single-storey rear extension can transform a cramped kitchen into an open-plan kitchen-diner, add a utility room, create a ground-floor bedroom or provide a dedicated home office. Many fall within permitted development rights, so you may not need planning permission.
- Solid masonry structure with insulated cavity walls and concrete slab floor
- Pitched tiled roof or flat GRP fibreglass roof options
- Large-format bi-fold or sliding doors and roof lanterns for natural light
- We handle the new roof for your extension as part of the build
Double-Storey Extensions
If you need space on both floors — perhaps a larger kitchen downstairs and an additional bedroom or bathroom installation above — a double-storey extension delivers significantly more usable area for a relatively modest increase in cost. The foundations and roof structure are shared between both levels.
- More cost-effective per square metre than single-storey extensions
- Adds substantial value to your Wembley property
- Our in-house team manages structural design and Building Regulations submissions
- Usually requires planning permission — we handle the full application process
Wrap-Around Extensions
Combining side and rear extensions, wrap-around extensions maximise available space and are particularly popular in Wembley for creating open-plan living areas that transform how you use your home.
- Creates a dramatic transformation of your living space
- Perfect for open-plan kitchen-dining-living areas
- Maximises the potential of corner plots
- Can incorporate multiple design features like roof lanterns
Loft Conversions
While not strictly an extension, loft conversions are another effective way to add living space without reducing your garden. We carry out dormer, hip-to-gable, Velux and mansard loft conversions. Our roofing expertise is particularly valuable here — we understand roof structures intimately and can advise on the most suitable conversion type for your property.
- No garden space required
- Often doesn’t require planning permission
- Creates bedrooms, bathrooms, home offices and playrooms
- Can include dormer windows or skylights

Extension FAQs
Frequently Asked Questions About Building Extensions in Wembley
Get answers to common questions about our building extension services in Wembley.
How much does an extension cost?
Every extension is different. The cost is driven by the size, the specification of finishes, the structural complexity, ground conditions and whether services like general building work, plumbing or electrics need significant rerouting. We survey each project individually and provide a detailed, fixed-price quotation so you know exactly what you are committing to. All surveys are free and carry no obligation.
Do I need an architect?
We can arrange architectural drawings as part of our service, so you do not need to appoint a separate architect unless you have a preference for doing so. For more complex or architecturally ambitious projects, we work alongside independent architects and are happy to collaborate with a designer of your choice.
Can you handle the kitchen or bathroom fitting as part of the extension?
Yes. This is one of the main advantages of working with us. Because we handle all trades in-house, your bathroom installation or kitchen design and fitting is integrated into the extension build from the start, rather than being handed off to a separate contractor at the end.
Do I need planning permission for an extension in Wembley?
Many extensions in Wembley fall under permitted development rights, meaning planning permission isn’t required. However, this depends on various factors including your property type, location, and the extension’s size and design. Extensions that exceed certain dimensions, affect the appearance of your property significantly, or are in conservation areas typically require planning permission. Our team will assess your specific situation during the initial consultation and guide you through any necessary planning applications.
How long does an extension take to build?
The time it takes depends on the type, size and specification. Single-storey extensions are naturally quicker than double-storey or wrap-around projects. Weather conditions, planning approval timescales and the complexity of the internal fit-out (for example, a full kitchen design and fitting adds time compared to a simple living room) all play a part. We provide a realistic programme with every quotation so you know what to expect before work begins.
