About Us

MTL Design specialises in architectural and design services for extensions and alterations of all sizes. We work across the West Midlands but mainly within; Solihull, South Birmingham, Warwickshire & Sutton Coldfield.

At the forefront of any works undertaken by MTL Design is the client’s needs and vision. We ensure that plans & associated documentation are personally presented and fully explained prior to any submission. MTL Design prides itself on delivering a high quality service and as a result the majority of our work comes through recommendation.


Every project is different and we tailor the extent of our work to suit your requirements. We will undertake projects from inception through to completion although the majority our work is typically planning and building regulation applications as outlined below.

1. Free Consultation and Quotation

Our initial visit to your home will allow us to discuss your ideas, provide advice on design solutions and answer any queries regarding planning, building regulations or any other statutory requirements. There is no charge for this initial consultation and normally only takes up to half an hour. We then follow it up with a written fee proposal based on the scheme and work required

2. Survey Stage

Following receipt of the quote, if you are happy to proceed we will arrange to survey the existing building and surrounding site. This can take some time depending on the property but it will give us a chance to discuss the proposals in more detail and highlight any potential alterations. Before leaving we will arrange a date to either re-visit with our initial proposals or send to you via email

3. Planning Drawings

Following our initial proposal you may want to tweak or amend certain features of your project. Our fee is fixed so you can revise the scheme as much as you like until you are happy. Once you have decided on a proposal and are happy we will submit your planning application for you via the on-line planning portal and keep you informed of progress. A hard copy of the planning application will be provided within the handover folder given to all clients at the end of our services

4. Building Regulations

During the planning process (as it can take up to 8 weeks) we start to prepare a more detailed set of drawings with structural calculations and details and this would also be the time where we would discuss other statutory requirements, for example Party Wall Notices or Building Over Sewer Applications. We will arrange to visit you soon after the planning decision to review the proposal and as long as you are still happy we will then submit the building regulations application to an Approved Inspector or the Local Authority

Obtaining Quotes

Unless previously instructed, you will then be responsible for obtaining quotes from Contractors. Following the approval of Building Regulations you will receive by hand a hard copy of all the approvals and documentation for your records together with two hard copies of the drawings for you to obtain quotes. We will also email a set of the approved drawings in PDF format should a contractor want them electronically. We would normally recommend at least three competent builders in writing when we personally hand over the documentation but you may already have someone in mind.


As every project is different we cannot give exact fee quotes here, but will price each project on an individual basis following an initial consultation. However as a guide our fees can start from as low as £750 for straight forward projects.

Our fees will always include all drawings, structural design, revisions and meetings as we believe offering one package makes life a little easier. Additional services such as Severn Trent Applications and Party Wall Notices will be discussed at the initial consultation and included within the quote if required.

Statutory fees such as the planning application or building control fee is not included within our fee but will be outlined separately on any quote.


1. What is planning permission?
Construction of new buildings, extensions and changes such as roof alterations to existing buildings usually requires consent from the local planning authority. The planning system is designed to control inappropriate development. Some extensions, alterations or outbuildings will however come under Permitted Development (PD) rights. The following link will open an interactive guide to see if you require planning permission https//www.planningportal.gov.uk/permission/

2. What are Building Regulations?
Regardless of whether planning permission is required building regulations is required on almost all domestic and commercial projects. The Building Regulations are minimum standards for design, construction and alterations to virtually every building. They are developed by the Government and approved by Parliament.
These regulations set national standards for building work, whether it be on a major new development or an extension or alterations to your home. They cover all aspects of construction, including foundations, damp-proofing, the overall stability of the building, insulation, ventilation, heating, fire protection and means of escape in case of fire.

3. Why are good quality, accurate plans so important?
There are a number of reasons why they are so important. Firstly, building plans are basically an instruction manual for your building work. They will indicate exactly what your finished project will look like and how it will work for you. Secondly clear and accurate plans will enable builders to quote on a like for like basis which will enable you to make a more informed decision when choosing a builder to use. Another reason is that they offer in a sense an insurance policy. We have all seen Cowboy Builders on TV but the reality is the plans which have been approved by Building Control officers are what should be built and you will have this proof if for any reason the builder is incompetent, protecting you from what could be a costly experience if you did not have approval.

4. Do I need any other permissions?
Achieving Planning Consent and Building Regulations approval does not necessarily mean that you have a legal right to carry out your building work. There may be covenants or easements restricting development on your site; if you are unsure you should check the deeds to your property or seek legal advice. If you are building over, or near to, a public sewer you will probably need to seek the consent of the owners of the sewer by entering into a ‘Building Over Sewer’ agreement. The Party Wall etc Act 1996 may also apply; this is not an approval or application but more like an agreement between neighbours to ensure there are no boundary or Party Wall disputes.

5. How long does the design process take?
There is a statutory eight-week period for the Local Authority to issue a Planning Decision. Building Regulations approval by the Local Authority can take up to 8 weeks but we often use Approved Inspectors which typically take 14-21days. Therefore from carrying out our initial survey you can expect the process to take a minimum of 2-3 months. This should be taken into account when you think about when you want your work to start.

6. Do I need someone to supervise my building work?
In short, no. Many home extensions do not need a separate project manager as long as a competent, professional builder is employed. The work will be checked periodically by the Building Inspector to ensure that the construction is being carried out in accordance with the plans and that it conforms to Building Regulations.

7. How do I find a good builder?
There are a lot of websites and information available but the best way is to ask. A good place to start would be if you have any friends, family or neighbours that have had building work done. Ask them for references and follow them up. As stated MTL Design will be able to suggest builders for your specific project, but it is important that you ask the right questions and find the builder that is right for you. Just remember the best builders will almost certainly not be the cheapest and don’t expect them to start tomorrow as good builders will normally have a queue!
