Loft Conversions in Lincolnshire

Looking for a loft conversion in Lincoln, Grantham, Grimsby, Scunthorpe, or anywhere else in Lincolnshire? CK Architectural can help.

CK Architectural provides loft conversion design plans across the whole of Lincolnshire, including the Lincoln, Boston, Grimsby and Grantham areas. They can be the simplest and the cheapest option for adding a room to your home, since you already have the space there, and there is a huge range of uses for them.

Bedrooms with en-suite and dressing rooms, cinema rooms, offices and even children’s play areas are all fantastic ways to utilise one, and with the right design, it’s incredible as to what they have to offer you. Each different type of conversion works in harmony with the requirements of your new space. With a dormer loft conversion, there’s more headroom for busier or more active rooms, and with more standardised conversions like rooflight or even hip to gable conversions, there is a more specific design, which needs careful evaluation.

This is all a part of the architectural design process, where we work with you on your loft conversion project to design the best fit for your own personal needs, using your ideas as well as our own.

The loft conversion process

Any kind of loft or roof conversion is an incredible way to maximise the space in your home using facilities you already have, boosting your property value and improving your quality of life all at the same time.

We offer specialised and tailored services designed to fit you and your unique needs perfectly, offering expert advice and guidance the whole way through the conversion process, starting from surveys, designs and concepts, and going through to planning, regs and even into the build itself.

We also offer a project management service to help you carry out your project with efficiency and accuracy to minimise stresses and complete to project with the utmost care. This ranges from us helping you to choose the builder and outlining contracts through to regular site checks and using us as your communication point where required to prevent any disputes.

Design considerations

Before beginning your loft conversion design, there are several aspects that should be considered. The design should be driven by what you want to incorporate, what you want to gain, what you can achieve, and what you are willing to compromise to get the end result.

The first thing to consider is the height that you need, as once you add floor joists and have insulated the rafters, the height soon starts to reduce. We recommend that you have a minimum of 2.4 meters (8 foot) from the top of the ceiling joist highest point to underside of the rafters.

The new flight of stairs will take room from the ascending floor and needs to land in the roof without encroaching too much of the usable floor space. Window options can be put in the roof using gable ends, velux’s, or by building a dormer.

We incorporate all of these things into every loft conversion design that we do to make sure that the remaining space is functional and can still fulfil your requirements without any issue.

We update you every step of the way through the entire project

Planning permission

Loft conversions can generally be done without the need for planning permission and the permitted development rights. When planning is required, the loft conversion will need to fit in with the street. If all the neighbouring houses have the same ridge height, you will not be able to raise yours. If the street does not have any dormers to the front, adding them would be considered abnormal.

Clear glazing can only be fitted a minimum of 7 meters from the boundary so typically you can only look out the front and rear. We will advise on the likelihood of gaining planning approval, prepare and submit this for you. The typical determination period is around 8 weeks for validation.

A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:

Planning permission guide

Loft conversion permitted development rules

  • A volume allowance of 40 cubic metres additional roof space for terraced houses.
  • A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses.
  • No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway
  • No extension to be higher than the highest part of the roof
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms.
  • Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
  • Roof extensions not to be permitted development in designated areas, i.e Greenbelt, areas of outstanding natural beauty, Conservation etc…
  • Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves.
  • The roof enlargement cannot overhang the outer face of the wall of the original house.

Building regulations

Legally, Building Control need to be involved when altering the structure of a roof and building certificate required for the resale or insuring of your property.

When creating habitable rooms like bedrooms, it is more than the structural integrity that will need upgrading. When designing a roof, your architect or architectural designer must consider the following:

  • Structure, the new floor joists and roof will need to be supported; this is generally done via steel beams designed by an engineer.
  • A protected fire route must be provided, this is 30 minutes all the way down to the final exit, existing doors will need upgrading to fire doors.
  • Detection and sounded alarms will be required and need to be interlinked.
  • The stairs will need sufficient headroom 2.0M and not be too steep (under 42 degrees).
  • Reasonable sound insulation between the conversion and the rooms below

All the designs we present to you will be with the intention of passing building regulations and construct able.

Loft Conversion Building & Project Management

Once you have your detailed drawing approved it is time to get some prices for the build and if required, we can recommend you, builders, we trust. There are specialist loft conversion companies out there, but with detailed drawings, most competent builders are more than capable. We advise that any quotation you consider will be written up clearly and well detailed, so both you and your builder know exactly what is included in the price or it can lead to disagreements at the end of the project.

We have extensive on-site knowledge and will always advise where we think areas need exploring or issues may arise during the build. We advise that you use our drawings in line with the quotation and any additional information we don’t provide such as plumbing and electrics is agreed upon in detail before the first fix goes in.

It is a costly exercise to change things once the initial preparations have been built. We offer help throughout for both you and the builder, we will happily come to the site if further help is required.
