Two Rooms in One - Made for Family Life
A P-shaped conservatory gives your household room to breathe. Whether you want a dining area at one end and a relaxed lounge at the other, or a playroom alongside a dedicated workspace, the dual-zone layout adapts to how your family actually lives.
For larger and detached properties in particular, the extended footprint of a P-shaped design delivers impressive, proportionate results. You gain generous usable space without sacrificing your garden, and the finished extension enhances your home’s kerb appeal from every angle.

Malbern Windows has been installing quality glazed extensions since 1983. As a family-run business, we take every project personally – from the initial consultation right through to handover. Our experienced installation teams work to the highest standards, with minimal disruption to your day-to-day life.
No two homes are alike, which is why every P-shaped conservatory we build is designed around your specific requirements. We’ll guide you through every decision – size, frame material, roof style, glazing and colour – so the finished result is exactly what you envisioned.
Frequently Asked Questions
Find answers to some of our most commonly asked questions below. If your question isn’t answered below, feel free to get in touch with our friendly team!
A P-shaped conservatory combines a lean-to section and a Victorian bay into one large, versatile extension. This gives you a bigger footprint and the unique ability to create two separate living zones within a single structure.
In most cases, planning permission is not required, as P-shaped conservatories often fall under Permitted Development rights. However, size, location and whether your home is listed can affect this — we'll advise you fully during your consultation.
Timescales depend on size, complexity and groundwork requirements. Most installations are completed within a few weeks once your design is finalised and any necessary permits are in place. We'll give you a clear timeline from the outset.
Yes. With the right glazing specification, quality insulated frames and effective ventilation, your P-shaped conservatory can be a comfortable, usable space throughout every season -regardless of what the British weather brings.
A well-designed conservatory can add around 5–10% to your property's value. A P-shaped design, with its generous floor area and dual-purpose layout, is particularly attractive to prospective buyers looking for flexible family space.

We have had an outstanding service from Malbern, dating back to 2014 when they built my conservatory, over the intervening years when we needed a small bit of maintenance under the guarantee, and most recently when they have replaced the glass roof with a solid roof, transforming the original design. This has given us a brilliant new room in 2024 and made our house feel much more spacious and better insulated. The build team took care of the whole process, doing a very professional clean and tidy job. I can't recommend more highly!

Just completed a full conservatory build and all we can really say is that we are extremely amazed at the quality of the end result. Fantastic, brilliant, overjoyed, perfect, better than expected. After the initial meeting we had a picture in our mind of what we wanted but the end result is so much better than expected. We certainly can't complain, it is a job well done and money well spent. Now it's time to enjoy the final end result. A massive thank you to all involved.

Malbern recently built us a large conservatory and a garden room. This was a massive job involving levelling a terraced garden and putting in retaining walls in addition to the conservatory and garden room construction. They did a fantastic job, all the work was done to a high standard and any snags were quickly dealt with.
