Common building projects
Builders can take on anything from masonry repairs to major renovation and extension work. For larger projects, the most useful quote starts with a clear scope, drawings or specifications where available, and an understanding of which specialist trades, approvals and inspections may be needed.
Single- and two-storey extensions, porches and other additions, including foundations, walls, openings, structural elements and coordination with the wider project team.
Whole-room or whole-property improvement work, from stripping back and making good to reconfiguring spaces and coordinating several trades through a larger refurbishment.
Opening up rooms, forming new openings, removing or altering walls and installing structural supports where designed and specified by the appropriate professional.
New walls, repairs, repointing, garden walls, steps, blockwork and other masonry work where a general builder or brickwork specialist is appropriate.
Garage conversions, internal layout changes and other projects that turn existing space into something more useful, subject to the right design, permissions and Building Regulations.
Smaller building jobs such as damaged masonry, local structural repairs, making good after alterations, external repairs and other work that goes beyond a typical handyman task.
Building work varies too much for one price to cover every project. A straightforward day of general building work and a multi-week extension should not be compared in the same way. For a useful local labour benchmark, current Birmingham builder guidance gives:
Indicative guidance checked August 2026. MyJobQuote currently lists about £40 per hour for a builder in Birmingham and an average day rate of roughly £290–£350. Larger projects are normally priced from the scope, drawings, access, materials, structural requirements, specialist trades, waste, scaffolding and programme rather than by multiplying a day rate. For context only, MyJobQuote’s current UK single-storey extension guide puts a typical average around £35,000, but real extension costs can vary very widely.

Quotes are far easier to compare when each builder is pricing the same drawings, finish level and responsibilities. A low headline figure can be misleading if another quote includes waste, scaffolding, materials, specialist trades or making good that the cheaper quote excludes.
Local to Birmingham
Your postcode helps match the project with builders who cover your part of Birmingham, whether you are planning an extension in Harborne, a renovation in Edgbaston, structural alterations in Selly Oak or general building work elsewhere in the city.
“Builder near me” is a local search, but builders also choose work based on project type, size, timing and travel. A team that takes on large extensions may cover a wider area than someone focused on small building repairs, so the postcode and a clear project description both help.
How it works
You do not need to ring building firms one by one. Explain the project once, then compare the suitable local options that come back.
Enter your Birmingham postcode and describe the work, current stage, approximate size, drawings or plans you have, and when you would ideally like to start.
Your requirements can be matched through our partner network, and up to 3 local tradespeople can contact you about the project.
Compare relevant experience, feedback, proposed scope, timing and quotes. For larger jobs, make sure you are comparing like for like before deciding who to hire.
Choose with confidence
For substantial building work, the cheapest quote is rarely enough information on its own. Check relevant experience, exactly what is included, how the work will be managed and what happens if the scope changes.
Ask for recent examples and references for projects similar in scale and complexity to yours. Extension work, structural alterations and full renovations require different experience from small general building jobs.
For larger work, agree the scope, responsibilities, insurance, programme, variation process and staged payments in writing. Avoid vague quotes that make it difficult to tell what is included or when money becomes due.
Planning permission and Building Regulations are separate. Clarify who is responsible for drawings, structural design, applications, building-control inspections and completion paperwork before work starts.
Builder or specialist trade?
A builder may coordinate several parts of a renovation or extension, but specialist work still needs the right trade and, where relevant, the right qualifications. Electrical work, gas work, roofing, plumbing and finishing trades may be carried out by separate specialists or subcontractors. Ask who will do each part and who is responsible for coordinating it.
Useful answers
Quick answers to common questions before posting a building project in Birmingham.
Enter the postcode where the work will take place and describe the project as clearly as you can. Include the type of work, approximate scale, any drawings or approvals you already have and your preferred timing. Your request can then be matched with suitable local builders through our partner network, allowing you to compare up to 3 quotes before deciding who to hire.
Current MyJobQuote Birmingham guidance lists about £40 per hour and roughly £290–£350 per day as local builder benchmarks. Larger projects such as extensions and renovations are normally quoted as a project because materials, structural work, specialist trades, access, scaffolding, waste and the finish level can dominate the overall cost.
Not every house extension needs a full planning application because some work can fall within permitted development rights, but the rules depend on the property and proposal. Birmingham City Council advises checking before starting work, and larger extensions or properties with restrictions may require permission or prior approval. Planning permission is separate from Building Regulations.
Many extensions and structural alterations do. GOV.UK states that you must check whether approval is needed before constructing or changing a building in certain ways, and that Building Regulations approval is different from planning permission. Clarify the approval route and who is responsible for inspections and completion paperwork before work starts.
For larger or structural projects, clear drawings and specifications usually make quotes easier to compare because every builder is pricing the same work. If structural calculations, planning drawings or a detailed schedule of works are needed, getting those in place before final quotes can reduce assumptions and later changes.
For substantial work, ask for a written breakdown covering the agreed scope, materials and labour, exclusions, waste removal, scaffolding or plant where relevant, specialist trades, VAT if applicable, start timing, programme and payment stages. Also agree how changes or extra work will be priced and approved.
Tradespeople using our partner service are verified with official identification, email and phone details. Public liability insurance and qualifications are checked where provided. You should still review each profile, feedback, relevant project experience, insurance and the detail of the quote before deciding who to hire.
No. Posting a project does not oblige you to hire anyone. Compare the builders who respond and choose only if you are comfortable with their experience, proposed scope, communication, timing, contract terms and price.
Post the building project once, let suitable local builders come to you and compare your options before deciding who to hire.
