Timber construction: compare quotes and prices

Which timber construction work do you need?

Tasks can include roof structures, dormers, timber floors, walls, facade cladding, extensions, additional storeys and smaller outdoor structures. Alterations and repairs to existing components may also be needed. Start with the component and the result you want.

Distinguish fabrication and delivery from installation and later finishing. A timber construction contract does not automatically provide a home ready to occupy. Furniture making, simple surface painting or pest treatment have different purposes and are not part of structural work without explicit agreement.

Describe the use and known geometry

The intended use influences the structure. An open plant support needs different coordination from a rainproof roof, an occupied extension or a loaded floor. State whether timber should remain visible and which neighbouring areas are affected.

Known length, width, height and area help with assessment. For several dormers or individual identical components, an exact count is useful. Different dimensions or several tasks can be described together. Unknown technical information can remain open initially.

Existing drawings or sketches can be provided later. Necessary dimensions, levels and connections need confirmation before manufacture. A rough measurement or a beam’s visible thickness does not establish its load-bearing capacity or a suitable connection.

Coordinate the construction system and prefabrication

Individual components can be assembled on site or delivered as prepared elements. Walls, floors and roof elements can be prefabricated in a workshop. The right approach depends on geometry, access, the intended assembly and connection works.

Prefabrication brings important decisions forward. Openings, service routes, connections and the supplied condition must be agreed in time. Changing a completed element can have different consequences from revising the design.

Quick erection of timber elements does not mean the whole project is finished in the same time. Design, preparation, foundations, roof covering, building services and fit-out have their own sequence. Ask for the promised completion condition to be clearly defined.

Plan structure, moisture and occupied use together

Responsible professionals determine the structure and connections for load-bearing or bracing components. Extensions and additional storeys also depend on existing bearings and the building fabric. A solution’s relatively low weight does not replace assessment of the existing structure.

Occupied timber buildings require consideration of winter and summer thermal comfort, airtightness, airborne sound and impact sound. These properties depend on the complete assembly and its connections. Timber species alone guarantees neither a particular indoor climate nor a universal energy or acoustic performance.

Fire protection also concerns components, connections and penetrations for services. Requirements and responsibilities depend on the project. Relevant checks belong to professional design.

Clarify timber protection and repairs to existing work

Timber needs to suit the intended exposure. Outdoors, drainage, protection from prolonged moisture, drying and connections matter. A fresh paint or stain does not replace suitable construction. Discuss future care and changes in appearance as well.

For repairs, visible damage, moisture marks or distortion help with the first description. The cause and affected load-bearing parts may need investigation. Replacing cladding does not automatically mean fully renovating everything behind it.

Transport, storage and installation need appropriate arrangements. Mention narrow access, the floor, setup space and continuing use. Agree who protects the building during open phases and who finishes roof, facade or window connections after the timber work.

Compare costs by services and finished condition

Area and timber quantity do not explain the price alone. Geometry, measurement, fabrication drawings, connections, visible surfaces and the assembly with insulation or linings affect the work. A single custom component is priced differently from a series of prefabricated elements.

Alterations can add dismantling, adaptation of the existing building and protection during the work. Delivery, lifting, installation and connections should be identifiable. Responsibilities for structural design, site preparation and other contractors also matter.

Compare the same completion condition. A price for a timber frame is not a complete price for an occupied room. Check quantity assumptions, unresolved existing conditions, material and surface specifications, and VAT. A general square-metre price without that scope provides little guidance.

Useful details for the initial enquiry

A short description is often more useful than choosing a technical method too early. Give the information you know and leave unresolved professional questions open.

• Services. State new construction, renewal, alteration, repair or delivery only.
• Structure and use. Describe the affected structure and its intended use.
• Dimensions and count. Add known dimensions and exact individual component counts.
• Existing parts and extras. Mention parts to retain and additional work you want included.
• Location and timing. Give the work location, floor, access and preferred timing.

Agree a coherent timber construction package

The necessary design depends on the project. Connections and responsibilities need clarification before components are fabricated or existing areas are opened.

1. Describe the task. Describe the task, use and known existing conditions.
2. Clarify the structure. Have dimensions, structure, assembly and connections clarified.
3. Compare quotes. Compare quotes for equivalent services and completion conditions.
4. Prepare erection. Agree fabrication approval, preparation, protection and erection sequence.
5. Check handover. Check the work, remaining connections, function and agreed documents at handover.
