exemplary in their workmanship
Dear Paul and Kevin,
We are very pleased with the appearance. The design, angles, guttering and profile of windows with mouldings all work well in our opinion. Thank you both for your input and steer to achieve the result.
Peter and Marcus were exemplary in their workmanship and helping me to understand and satisfy my curiosity. They battled against very high temperatures and a June which had over 200% of the average rainfall in our area. Very grateful to them.
Kind regards,
Mr & Mrs Armstrong

Most Asked Questions
Is planning approval required for a conservatory, orangery or oak extension?
Usually not, since you are permitted to expand up to 6 metres for semi-detached/terraced houses and 8 metres for detached residences. If you reside in AONB or a National Park, you will usually require Planning Approval before constructing a glazed extension. The process of getting planning approval can be complex as well as time-consuming due to the quantity of documents required. At Hallmark, we believe that developing your new living space need not be so demanding. That is why our planning permission specialist will gladly deal with all on your behalf.
Will the conservatory or orangery get too warm in summer as well chilly in the wintertime?
Your new space will certainly be usable throughout the year as a result of the highest specification of solar regulated glass available. This means using reliable glass that gives as much as 86% warm deflection on a hot day as well as maximum warm retention on a chilly day. Ensuring your new living space is comfortable despite the time of year. We also advise using roof vents that help manage the temperature environment by releasing hot air when called for.

These include why you want to use your new living space as this will dictate the appropriate size. The design style is based either on personnel preference or what suits the property. The aesthetics of the design choice will reflect the frame material options i.e. upvc, aluminum or painted hardwood.
Along with associated building work such as base and brick work, electrical requirements, underfloor heating as well as flooring options.
