Detailed plan
for the clubhouse
The club plans to build a clubhouse at the facility to improve amenities, including a toilet and shelter from the weather. The plan will be reviewed by the landowner and architect before construction begins.
Overall timeline
From groundwork to finished clubhouse, four months of structured progress.
Groundwork and foundation
Excavation of pillar holes to a depth of at least 80 to 100 cm. Pouring of 14 concrete pillars. Anchoring with threaded rods.
Walls and roof structure
Erection of wall framing, installation of top plates, and roof construction with the correct pitch for drainage.
Cladding, insulation, and interior panels
Exterior cladding (372 linear meters of boards), wind barrier, roofing, windows, and sliding doors installed.
Final completion and interior fit-out
Electrical connection from the garage. Water supply from the tennis court tap. Interior fit-out and final completion.
Foundation and pillars
14 concrete pillars in a strategic grid pattern ensure even load distribution and a stable base for the entire structure.
Excavation
- Depth: 80 to 100 cm depending on frost line
- Placement: 4×4 grid
- Purpose: Below frost depth
Concrete tubes
- Standard ground: 250 mm diameter
- Soft ground: 300 mm diameter
- Anchoring: Threaded rods
| Component | Weight (kg) |
|---|---|
| Walls | 3 240 |
| Roof | 1 800 |
| Floor | 1 800 |
| Total weight | 6 840 kg |
| Number of pillars | 14 pcs |
| Parameter | Value |
|---|---|
| Volume per pillar | 0.0707 m³ |
| Total concrete volume | 0.99 m³ |
| Number of bags (25 kg) | 77 pcs |
From sill to roof
Three connection points define the structure: floor to wall, wall to wall, and wall to roof.
Floor to walls
- Method: Sill beam and nails/screws
- Sill membrane between concrete and bottom plate
- Bottom plate 48×98 mm or 48×148 mm
- Threaded rods and washers for anchoring
- Long screws or nails 90 to 120 mm
Procedure
- Lay sill membrane between concrete and bottom plate
- Fasten the bottom plate with anchor bolts into the concrete
- Screw the bottom plate to the floor joists with long screws
- Use nail plates at joints for extra strength
Wall to wall
- Method: Overlapping corners
- Wall framing 48×98 mm or 48×148 mm
- Angle brackets, cheaper than long screws
- Galvanized nails 75 to 90 mm
- Nail plates for extra reinforcement
Procedure
- One wall runs continuously, the other butts against it
- Fasten corners securely with angle brackets
- Secure with long 90 mm screws
- Add cross battens at the transitions
Wall to roof
- Method: Top plate + angled screwing
- Top plate 48×98 mm or 48×148 mm
- Wood screws 120 mm or nails
- Slope: 20 to 30 cm per meter of roof width
- Roof joists approx. 60 cm spacing
Procedure
- Attach the top plate, with one long wall higher for slope
- Install roof joists with angle brackets
- Lay roof sheathing (plywood/OSB) + roofing
- Install gutters and downpipes on the lowest side
💡 Most cost-effective solutions
Use nails instead of screws where possible, as nails are cheaper. Buy angle brackets in bulk to reduce unit cost. Use offcuts and leftover materials for cross battens in corners and joints. Build with overlapping corners instead of using additional fastening hardware.
Cladding, boards and wind barrier fabric
Footprint 30 m² (6×5 m), wall height 3 m. Calculations include 10% waste.
| Parameter | Value |
|---|---|
| Total wall area | 66 m² (22 m × 3 m) |
| 3 windows (1.2×1.2 m) | − 4.32 m² |
| 2 sliding doors (3×2.1 m) | − 12.6 m² |
| Net cladding area | 49.08 m² |
| With 10% waste | 54 m² cladding |
| Calculation | Result |
|---|---|
| Board width | 16 cm = 0.16 m |
| Area per linear meter | 0.16 m² |
| Total linear meters | 337.5 lm |
| With 10% waste | 372 linear meters |
| Wind barrier fabric (6 rolls of 10 m²) | 60 m² |

Electrical work: Rustad will engage an electrician. The club’s preferred solution is to receive sponsorship for the electrical work from a local provider.
A clubhouse built
through voluntary effort and determination.
The plan will be reviewed by the landowner and architect before construction begins. Completion is planned for the end of July 2025, a new chapter for Konglungen Tennis Club.
