Our Process

Professional Loft Plans Specialists | Complete Loft Plans Packages

Our entire process is designed to make things as quick and simple as possible for you. We take on all of the stress, leaving you to just approve the designs and look forwards to a new living space inside your home.

After the survey we will draw up plans of existing layouts and elevations so that we can progress to the design stage of your new loft conversion.

We will submit the relevant application to the local authority, whether that be an application for a certificate of lawfulness (Permitted development) or a full planning application, and we will monitor this application for you, dealing with any queries the local authority may have.

Standard householder planning approval usually takes around 8 weeks for the local authority to determine. If we already know that your loft conversion application falls under permitted development, as most do, there will be nothing to worry about as we will have created your plans to keep within the permitted development requirements.

Why Us?

We know the business of loft conversions inside out.  We have years of experience designing loft conversions but what makes us different from the rest is our in house building experience, having built hundreds of loft conversions over the years.

Having this experience means that we understand what works, we understand how to get the most from your space, and with our in-depth knowledge will work this around your budget should you have a more complex project.

We can talk you through your options for stairs and work out the position and design of your stairs there and then on the survey. So you will know what expect even from the initial survey rather than your first drawings being sent and realising the stairs have taken up more space than you expected leading to lots of unnecessary revisions.

Unlike architects who have no building experience, and no idea how much materials and labour will cost, we can create your drawings and build your loft conversion taking all these factors into account, saving you a lot of stress, time and money.

Most loft conversions fall under permitted development, so as long as your drawings fit with the requirements, you are guaranteed approval. Where planning permission is required, we will liaise with local authorities and ensure that your planning application is stress free.

  • No Hidden Fees

    Many architectural design companies lure you in with cheap initial drawings, then surprise you with very expensive Building Regulations Drawings and Structural calculations. We provide a complete package that provides everything you need to move onto the build stage, with no surprise costs.

  • Fast Turnaround

    We aim to complete the survey of your property within a day or two of your initial enquiry. We will then create your plans within 1 week of your survey, and your structural drawings and calculations a few days later. Planning applications will be made and managed in a timely manner.

  • Building Experience

    We've built hundreds of loft conversions over the years so we not only understand structural design and planning regulations, we also understand the building process, the materials and the labour costs. Having this experience allows us you help you get the most from your space and the most from your money.

Frequently Asked Questions

What is a Permitted development?

Under new regulations that came into effect from 1 October 2008 a loft conversion for your house is considered to be permitted development, not requiring a full planning application, subject to the following limits and conditions:

  • A volume allowance of 40 cubic metres additional roof space (above existing roof line) for terraced houses.
  • A volume allowance of 50 cubic metres additional roof space (above existing roof line) 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 part of the front roof can protrude more than 0.15m above front roof slope.
  • 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.
  • Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the eaves.

Permitted Development Rights are a more relaxed version of Planning. This is not granted by the local authority but by parliament.

Permitted Development allows homeowners to make alterations to their properties quickly without having to go through full planning.

Although they're not mandatory there is an important document that you should get called a Lawful Development Certificate, LoftPlans always advise clients to get this, so we will fill out the necessary application for you as part of our service.

Homes in conservation areas, or buildings which have a listed status, have had their Permitted Development Rights removed.  It is also not uncommon for a building to have had its Permitted Development Rights removed under a condition attached to the original planning approval at the time at which it was built, if it was built since the permitted devlopment started.

If you are unsure as to whether your house has Permitted Development Rights, you are often able to check by calling your Local Planning Authority and ask to speak to a duty planning officer, who should be able to advise. We will carry out this process should you instruct to carry out your Loft plans.

What is a Certificate of Lawfulness?

A Lawful Development Certificate is a legal document stating the lawfulness of the development. By applying for a Certificate of Lawfulness (Proposed), you are seeking formal confirmation that planning permission is not required and that you can undertake the work lawfully. A Certificate of Lawfulness (Proposed) is a formal and legal document confirming this. This can be beneficial when you come to sell your property.

Do I need a Certificate of Lawfulness for a loft conversion?

A Certificate of Lawfulness is neither mandatory or a legal requirement for a loft conversion. However, we always advise our clients to obtain one because of the benefit and future assurance they offer.

Certificates of Lawful Use or Development for a loft conversion can be particularly beneficial when it comes to either buying or selling a house. Solicitors who represent the buyer will almost always require documentary evidence that proves that the loft extension is completely lawful. The evidence provided by the Certificate of Lawfulness can therefore often help with the sale of the house by proving this to the buyer.

As Certificates of Lawful Use or Development provide the necessary evidence that any work carried out has been done legally, they can also help in the event that a neighbour queries the work or has a complaint to make.

How do I get a Certificate of Lawfulness?

To obtain a Certificate of Lawfulness for your loft conversion, we will need to submit an application to your local planning authority through the Planning Portal or council website. Alongside your application, copies of drawings of the existing and/or the proposed development and a site location plan will need to be submitted online.

After the application has been submitted to the local authority, one of their officers will be assigned to assess your application, arrange an inspection of the building site and check any plans from the property’s development history.

How much does a Certificate of Lawfulness cost?

We include the drawings and structural calculations and will make applications for your LDC and building control but certificate fees and inspection fees are to payable by client, the LDC fees are £135 you will receive an email from the planning portal directly once we have made application, building control fees will vary from borough to borough.

Can the loft conversion be started before the Certificate of Lawfulness has been approved?

We always advise our clients to wait for the work to be started until the Certificate has been properly issued. It usually takes 8 weeks for the certificate to be approved once it has been submitted to the local authority.

Do I need to notify my neighbours? (Party Wall Act)

If your home is semi-detached or terraced, then you will need to notify your neighbours of your planned work if it falls under the requirements of the Party Wall Act.

Unless your property is detached there will be a party wall separating you from your neighbour's house. Most loft conversions involve alterations to party walls, usually to support steel beams. Under the terms of the Party Wall Act, it's a legal requirement that adjoining neighbours are formally notified before alteration work commences. This may require the appointment of a Party Wall surveyor.

What building regulations do I need to consider?

When it comes to loft conversion building regulations there is one rule you need to know – loft conversions always need building regulations approval, irrespective of whether planning permission is required. We will prepare building regulations plans, structural specifications and calculations and, ultimately, ensure the project complies with building regulations to ensure you get approval.

Inspections will be carried out In order to gain your building regulation approval, your loft conversion will need to be inspected, either by your local authority or a approved building control officer. You can expect it to cost around £500-£800+VAT for this service, we will do the application for this on your behalf if required, some builders have there preferred approved inspector so it’s best to get your builder in place before we make application.
