We are architectural designers and installation specialists, not general builders. Our singular focus guarantees a structure that is perfectly engineered and aesthetically uncompromising.
Concealed or Exposed Fixings
We offer both concealed fixings for a clean, monolithic appearance, and exposed structural hardware for traditional or rustic aesthetics. All fixings use stainless steel or hot-dip galvanized components for maximum durability.
Guaranteed Timber Grade
Sustainably sourced, kiln-dried timber, specifically treated to handle the high moisture and temperature fluctuations of the UK climate.
Cheshire Focus
Deep understanding of local architectural styles and planning constraints across the entire region, from Macclesfield to Chester.
In most cases, yes – you can build a pergola in England without planning permission under Permitted Development rights. Specific size, height, and location criteria must be met to qualify.
Pergolas must not exceed 2.5 metres in height if located within 2 metres of a boundary. Structures further from boundaries can be taller but should remain under 4 metres for single-storey outbuildings.
Total coverage of all outbuildings and structures (including your pergola) must not exceed 50% of the total area of land around the original house.
Pergolas should not be built forward of the principal elevation (front) of your house facing the road, unless you have planning permission.
Professional Recommendation:
We review your design against Permitted Development criteria during our initial consultation and advise when formal planning submission is necessary. For complex or boundary-sensitive projects in Cheshire, we recommend early engagement with your local planning authority.
In most circumstances, yes – portable outdoor kitchens and temporary structures can be built without planning permission under Permitted Development rights. However, permanent fixed installations with utilities and substantial built elements often require formal consent.
Professional Recommendation:
Timber Garden Studio reviews all outdoor kitchen designs against Permitted Development criteria and Building Regulations during initial consultation. We coordinate with Gas Safe engineers, electricians, and Building Control to ensure full compliance across utility installations and structural elements.
Visualizing your future outdoor space eliminates uncertainty, allowing you to approve every detail before construction starts. Over 90% of UK timber pergola and outdoor kitchen designers do not provide visualization services, leaving customers with worry about the final result. We offer a sharp, high-definition 3D design service for both pergolas and outdoor kitchens to guarantee clarity and eliminate costly revisions.
The exclusive no-visit rate is £99 for residents of the entire Cheshire and Wirral postal regions, including the Chester City Council district. The standard fee for all other UK residents is £179. This service is available nationwide regardless of who builds your final structure.

We offer engineering analysis for large, complex, or non-standard timber structures. This service provides peace of mind and formal documentation for ambitious projects.
£300 up to £1,697
The cost depends directly on the complexity of the structure (e.g., span, height, roof loading, anchorage to existing buildings). We provide formalized calculations verifying structural integrity.
Skipping engineering review for large or unconventional timber pergolas commonly leads to structural failure. Without proper calculations for beam sizing and foundation anchorage, situations like rafter sag, post shifting, and catastrophic collapse during severe UK weather (strong winds, snow loading) can occur. Structural failure of this type always results in significant repair costs, which often exceed the original construction budget.
Permitting is typically required for larger or more permanent structures in specific circumstances. A pergola will usually require planning permission if the height exceeds 2.5 metres within 2 metres of a boundary, or if the structure covers more than 50% of the land around the original house. Attached structures that impact access to fire escapes or encroach significantly on a boundary line also often trigger Building Control interest. We review your design against Permitted Development rights to advise when professional submission is necessary.
Do I need planning permission?
Most freestanding pergolas under 2.5m high and covering less than 50% of the garden fall under Permitted Development. Taller, attached, or conservation-area projects often require planning; ask us to review early.
How do you handle drainage and snow/wind loads?
We specify footing depth and anchor systems for uplift and lateral loads, and add guttering or integrated drainage where surface water is a risk. Snow load and wind exposure are factored into beam sizing on engineered builds.
Can you anchor on patios or composite decking?
Yes. We core through slabs/decking to reach structural concrete footings or install ground screws where appropriate. Surface-only fixings are avoided to prevent movement.
Do you attach to houses?
We can wall-attach with proper flashing, fire separation, and load checks. Where walls are unsuitable, we design freestanding frames tight to the facade.
What about power for lighting or heaters?
Qualified electricians handle feeds, isolation switches, and cable routing inside the structure. We can pre-run conduit for future upgrades.
What warranties do you offer?
Workmanship warranty is standard; finish and material warranties vary by timber species or aluminium supplier. Documentation is provided at handover.
Is a timber pergola cheaper than an aluminium one?
Initial material cost for pressure-treated softwood timber is typically lower (£30-£75/m²) compared to powder-coated aluminium (£80-£200/m²). Total lifecycle costs favour aluminium: timber requires biennial sealing (£200-£400/year), while aluminium needs minimal maintenance (£0-£50/year). Over 20 years, a timber pergola can cost £6,000-£10,000 including upkeep, while aluminium totals £4,000-£4,500. Premium hardwood (£60-£150/m²) offers longevity between the two, requiring less frequent treatment than softwood but more initial investment than standard aluminium.
Compare materials, roof styles, and add-ons to understand how design choices influence total investment for a permanent structure.

💡 How to use this result:
If your pergola is 4.0m wide and you want a 10° slope, one side needs to be 0.70m taller than the other. For example, if the low side is 2.5m tall, the high side should be 3.2m tall.
Costs typically start around £10,000 to £12,000 and often range between £18,000 to £30,000. High-end setups, such as those with large cooking runs, integrated premium appliances, and louvred roof systems, can exceed £40,000. In areas like Cheshire or the Wirral, a bespoke, design-led outdoor kitchen that includes both the kitchen build and a high-quality pergola or roof structure is generally priced between £25,000 and £60,000. This aligns with the premium segment of the UK market, which values customisation, material quality, and full garden integration.
A permanent roof or pavilion improves all-weather usability, which UK buyers value, and can make the installation read as a more "architectural", semi-permanent feature rather than a movable BBQ and furniture set. In many mid- to high-value UK areas, such as Cheshire, Surrey, or Greater London, a well-designed outdoor kitchen with a permanent roof or freestanding pavilion can enhance both buyer appeal and home valuation.
Real estate agents and home improvement analysts often report that outdoor upgrades like kitchens with covered structures can recoup a substantial portion of their investment, sometimes adding 5-10% to the property's resale value, depending on design quality and location. Be careful, as oversized or poorly sited pavilions that dominate a small garden, feel "too personal", or look like DIY bolt-ons can turn buyers off or limit uplift.
Basic outdoor kitchen (minimal or no cover): From £3,000 to £5,000 for a small setup that includes a standard BBQ, a simple countertop, and limited storage. More complete setups with better finishes and components usually range from £8,000 to £15,000. Bespoke kitchen with appliances and storage: Many UK outdoor kitchen specialists quote custom-built packages at £10,000 to £20,000, with high-spec or luxury installations frequently reaching £30,000 to £40,000, depending on design complexity and material choices.
Simple timber pergolas or budget aluminium canopies may be listed in general pricing guides at £500 to £5,000, but these are basic options with little or no integration.
Modern aluminium or louvred pergolas, such as those by Renson or Brustor, typically start at £8,000 to £9,000 for a 3×5 metre system. Custom configurations, premium finishes, and motorised roofs can increase pricing to £20,000 or more. Some well-known brands list their typical installed range as £5,000 to £25,000, depending on features and scale.
The core kitchen setup includes a built-in grill or BBQ, quality countertops, outdoor-rated cabinets, and utility connections (power, and often gas and water). These components alone generally account for £8,000 to £20,000, depending on the brand, materials, and kitchen length.
In the roof or pergola structure (pavilion) this includes posts, foundations, drainage, and options for integrated lighting or heating. Good-quality roof systems typically add £5,000 to £15,000, and more if the design is oversized, motorised, or highly customised.
UK companies offering full-service outdoor kitchen design and installation often start at £10,000 to £12,000 for an entry-level custom kitchen. When paired with a mid-to-high-end pergola or roof system, a £25,000 to £60,000 range is typical for premium, design-focused projects. This pricing reflects the needs of clients seeking more than just a BBQ area such as integrated layouts, luxury materials, and a permanent garden feature.
Close-up details that show footing integrity, drainage, joinery, and lighting integration.
Bespoke builds deliver larger spans, concealed anchors, engineered footings, and premium materials that live 20–30+ years with lower long-term maintenance; kits stay budget-friendly and fast but cap around 4.2m × 3.6m, rely on lighter fixings, and typically need more upkeep or replacement.
These kits offer a fast, cost-effective initial solution, typically mass-produced and sold by companies like Rowlinson, Rutland County, or large retailers.
Verdict: Kits excel in low upfront cost and immediate availability. They fall short dramatically on structural rigidity, size flexibility, and long-term durability, often requiring replacement within 5-10 years.
We provide permanently installed structures using architectural design principles, built to outlast the property itself.
Verdict: Our service excels in longevity, structural integrity, and perfect design integration. The initial cost is higher, but the lifecycle value and reduction in long-term maintenance make it the superior permanent solution.
Understanding the trade-offs between construction type, material investment, and long-term durability is essential for permanent outdoor structures.
⚠️ Important Warranty Information
These warranty periods and lifespan estimates assume timber is left unpainted and unmaintained. Regular treatment, sealing, and proper maintenance can significantly extend the life of your pergola. Pressure-treated softwood requires biennial re-sealing (£200-£400/year), while hardwoods need treatment every 2-3 years (£150-£300). Without maintenance, natural weathering and decay will reduce structural integrity over time.

A pergola is a garden structure made of vertical posts that support crossbeams and an open lattice roof. It provides partial shade and is often used to create defined spaces like walkways or seating areas.
Pergolas became popular during the Italian Renaissance and are now used in both residential backyards and commercial outdoor areas. Modern pergolas can include slatted or louvered roofs, or support climbing plants, offering both shade and airflow while allowing natural light to pass through.
Features an open lattice roof supported by vertical posts. Offers partial shade while maintaining airflow and natural light. Ideal for walkways, seating areas, and supporting climbing plants.
Freestanding structure with a solid roof and open sides, typically octagonal or round. Provides complete overhead protection from sun and rain. Often used as a focal point in gardens.
Larger structure with a solid roof and typically rectangular design. Offers full weather protection for outdoor entertaining. Common for dining areas, outdoor kitchens, and event spaces.
An outdoor kitchen with a roof is a covered cooking and dining space that includes built-in appliances, countertops, storage, and utilities. Unlike simple grill setups, it provides full kitchen functionality along with overhead protection from sun, rain, and snow. The roof structure can take several forms, including pergolas, solid covers, or pavilions.
Often, the outdoor kitchen is under a roof, making the space feel like a pavilion. A pavilion can be with or without a kitchen setup, and it's a freestanding structure with a fully covered roof, typically supported by four or more posts. It offers complete weather protection and is ideal for larger outdoor kitchens that require more enclosed shelter.
Common roof types include adjustable louvered systems for flexible shade, solid roofs for total coverage, and slatted pergola designs that allow filtered sunlight. Professional installations often include gas lines, electrical wiring, plumbing, and drainage systems. These setups must meet Building Regulations and outdoor safety standards for appliances.
