A glazed extension should be more than just a bolt-on room; it should be an architectural enhancement that’s built around the way you live. But if you’re seriously considering adding a new space to your home, one of the first things you’ll ask is: What’s included in a bespoke conservatory build?
It’s a fair question, and one that sets the best providers apart. This guide walks you through what’s included in a full-service glazed extension from Hallmark Glazed Extensions, from foundations to final finishes.
What Makes a Conservatory or Orangery “Bespoke”?
A bespoke conservatory or orangery build isn’t simply a conservatory or orangery by another name. It means the entire design, construction and finishing process is tailored to your property, your layout, and your lifestyle.
It goes far beyond choosing a colour or frame style. A bespoke build takes into account:
- The architecture and age of your home
- Your preferred layout, heating, and door configurations
- Specific glazing needs (privacy, sun exposure, conservation restrictions)
- Full control over the materials, finishes and design flow
With Hallmark Glazed Extensions, every detail is handled in-house, ensuring a cohesive, consistent, and carefully managed experience from start to finish.
Our Process: From Design Consultation to Completion
Every custom-built orangery or conservatory begins with a clear, structured process designed to reduce risk, remove stress, and deliver a result that genuinely adds value to your home.
1. Free Design Consultation
This is where the journey starts. We visit your property, talk through your vision, and assess what’s architecturally feasible. At this stage, we’ll look at:
- Access and layout options
- Roof types and structural requirements
- Planning permission, if needed
- Your design preferences and budget
We’ll also advise on what’s possible based on your home’s age, materials, and setting — especially important if you live in a conservation area or listed building.
2. Bespoke Design and Planning
Once you’re happy to move forward, we begin the design phase. This includes:
- Tailored CAD drawings to visualise the space
- Frame and glazing specifications
- Matching roof pitch, brickwork or render
- Door configurations (French, bi-fold, sliding)
- Layout decisions based on how you’ll use the room
We also handle any planning applications or building control processes needed — no third parties, no surprises.
3. Construction and Groundworks
While we don’t undertake the groundwork and base construction in-house, we work closely with trusted builders or your chosen contractor to ensure this crucial phase is handled professionally and in line with the overall design.
This typically includes:
- Excavation and poured concrete foundations
- Drainage and service access where required
- Dwarf walls or full-height walls using matching materials
- Installation of insulation layers and damp-proof membranes
We provide clear guidance on what building work may be needed, and can recommend builders we’ve worked with successfully in the past. Alternatively, we’re happy to liaise with your own contractor.
Your builder will handle the groundwork and base phase, using the detailed base plan drawings we supply to ensure everything aligns perfectly with your bespoke glazed extension.
Once complete, our team returns to install the frame, glazing, roof, and weathering to integrate your new space with the existing property.

How Long Does a Bespoke Orangery or Conservatory Project Take?
The project timeline varies depending on complexity and planning requirements. Typically:
Stage | Estimated Timeframe |
|---|---|
Initial consultation | 1–2 weeks to schedule |
Design and approvals | 2–6 weeks |
Groundworks and base | 1 - 2 weeks |
Frame and glazing install | 2 – 4 weeks |
Heating, finishes, QC | 1–2 weeks |
Typical total | 6–8 weeks (depending on size and weather) |
If planning permission is required, this can add 10–12 weeks; however, we’ll advise you at the outset and manage the process on your behalf.
Why Not All Conservatory or Orangery Builds Are Equal
Templated or kit conservatories or orangeries may look similar on the surface, but they rarely match the quality, comfort or long-term performance of a true bespoke conservatory or orangery build.
Key differences include:
- Materials: Bespoke builds use higher-grade frames and glazing with thermal efficiency in mind
- Installation: Managed by skilled professionals, not third-party contractors
- Design integrity: Tailored to your home’s footprint and layout, not retrofitted
- Longevity: Built to last for decades, not just a few seasons
