Bespoke Conservatory Design Services

Marston & Langinger’s reputation was founded upon high-quality wooden structures. Today we create the same beautiful designs using aluminium; a strong and durable material that offers flexibility in providing design solutions.

By nature, aluminium is incredibly light yet it has a high strength to weight ratio. This allows us to use more glass and make the most of the natural light available to your garden room, with less obstruction to the outside views. You may have noticed manufacturers of wooden conservatories are increasingly using aluminium to support their structures, which is a testament to the superiority of aluminium.

The Design Process

We have an in-house team of highly skilled Design Engineers who have experience in working across personal and professional home improvement projects. We’ve outlined the process of how we bring your structure to life below.

At the beginning, we will chat through what you are looking for, share some examples of previous projects and gain an understanding of your style and design preferences. This allows us to come up with some initial costs so we can align your dream structure with your budget.

  • We will visit you at home or the site where you want the structure to be situated.
  • We discuss how you want to use the space and your preferences on the style and type of structure. We can then identify whether you are looking for a traditional or contemporary structure and if you envisioned a conservatory, orangery or garden room.
  • You can browse our range of colours and we will leave you with a selection of powder-coated aluminium swatches so you can spend time making your decision.
  • During our visit, we will measure and photograph the space, carrying out a survey on the site. This will allow us to put together some initial design concepts and rough sketches.
  • We will then send you the sketches with a proposal for your garden room.
  • Once you have placed your order and paid your deposit, we will carry out a detailed survey to produce a 3D CAD* model of your structure, from which a detailed set of drawings or Ground Plan will be produced. We will talk you through these drawings so you to confidently sign off the specification. Once approved, your builder will be sent a laminted copy so the ground works can start, getting everything ready for the installation of the structure.

*Computer-aided design – we also use computer-aided analysis tools to identify local environment conditions. This means that your garden room is designed in accordance with British materials standards, relevant wind and snow loading regulations, and engineered to minimise heat loss.

Design & Engineering Service

For large scale and complex projects, we offer a design and engineering service – the cost for this will be tailored for delivering the exact requirements of your project and is often used in conjunction with your architect. This service involves three parts, the design preparation where a UK engineer will assess the local conditions regarding wind and snow loads. The second phase will be the initial design of the portal frame and basic loadings of the structure, identifying key aspects for the local engineer to consider the foundation and wall detail that will be required. Step three is where the full and final ground plan is produced and submitted to the client.
